Annex D: Form of Contract

Helen Keller Intl supports the supplementation with high dose of Vitamin A of up to 40 million children every year in 14 countries of sub-Saharan Africa. When delivered twice a year to at least 80% of children aged 6 to 59 months in countries with high under five mortality and high rates of vitamin A deficiency, Vitamin A supplementation (VAS), can contribute to a reduction of child mortality by up to 24%.

VAS is delivered to children twice a year through multiple delivery mechanisms. Some countries are organizing mass distribution campaigns in which teams of distributors visit every household to administer vitamin A to children. Others have integrated VAS into their facility-based delivery systems alongside routine immunization or growth monitoring. A third group of countries are using a hybrid system that combines campaigns and facility-based delivery.

The campaign strategy is organized twice a year in all health districts. It includes mass awareness activities and outreach by administrative mobile teams. These campaigns can be combined with other interventions such as deworming, azithromycin administration, pediatric praziquantel administration, or nutritional assessment.

In Nigeria, Helen Keller International supports the delivery of VAS in Adamawa, Benue, Ebonyi Nasarawa and Taraba states through a combination of outreach campaigns and facility-based delivery. Campaigns are organized twice a year, typically around May/June and November/December, and are implemented by the Ministry of Health with financial and technical support from Helen Keller International. In addition to VAS, campaigns may be integrated with other child health and nutrition interventions, depending on national policy.

To ensure high-quality campaign implementation and generate timely, objective, and independent evidence of performance, Helen Keller International conducts independent monitoring during each campaign. This monitoring follows World Health Organization (WHO) guidance originally developed for polio campaigns and applies to a two-stage, risk-based sampling approach. Communities are purposively selected based on their likelihood of being missed, taking into account factors such as remoteness, accessibility, urban or peri-urban characteristics, and historical VAS coverage.

Independent monitors visit selected communities after the passage of distribution teams and survey a minimum of ten (10) households per community. Where gaps are identified, the sample is expanded to fifteen (15) households to confirm coverage levels. If three or more households are found to have eligible children who did not receive vitamin A, the locality is classified as insufficiently covered and the information is immediately shared with health authorities to trigger corrective actions, including rapid mop-up. This approach enables real-time identification of missed populations and supports prompt improvements in campaign performance.

In 2026 in Nigeria, Helen Keller Intl will support the distribution of VAS in 5 states of the country Adamawa, Benue, Ebonyi, Nasarawa and Taraba through campaigns where distributors visit households in the community to administer VAS to target children. These campaigns, which last between 4 and 5 days, are organized twice a year, during the months of May/June and November/December of each year, and are implemented by the Ministry of Public Health with financial and technical support from Helen Keller Intl. Other services provided during the campaigns include deworming children aged 12-59 months with Albendazole or Mebendazole by distributors, screening for vaccine-preventable diseases, and routine vaccination catch-up in health facilities.

To this end, Helen Keller International seeks to recruit a consulting firm to conduct, in close collaboration with the country team and implementing partners:

two (2) independent monitoring exercises of VAS campaigns (first and second semesters 2026);
one (1) independent monitoring exercise dedicated to ORS + Zinc distribution during first round of MNCH Week Campaign in Bali Local Government Area of Taraba State; and
one (1) independent monitoring exercise dedicated to quality control of the postevent coverage survey (PECS) for VAS and ORS + Zinc.

The first campaign monitoring is planned for May-June 2026, and the second for November– December 2026. Independent quality control monitoring of the PECS will be conducted in May-June 2026, depending on the survey implementation timeline.

Description of independent monitoring of the campaign and the PECS survey

Independent monitoring of vitamin A supplementation (VAS) campaigns will be implemented in Adamawa, Benue, Ebonyi, Nasarawa and Taraba states while independent quality control monitoring of the post-event coverage survey (PECS) will be implemented in Adamawa, Nasarawa and Taraba States supported by Helen Keller International. In Benue and Ebonyi states, some Wards will be excluded from independent monitoring of Vitamin A Supplementation campaign because they are implementing routine Vitamin A Supplementation as such, campaigns will not happen in those Wards

In Bali LGA of Taraba State, there will be a pilot distribution of ORS + Zinc, and it is expected that independent monitoring will be conducted in that LGA specifically to monitor the distribution of ORS + Zinc. The age group for this distribution is for children under 5 years (0-59 months).

Independent monitoring of the campaign will be conducted simultaneously with the implementation of VAS campaigns and ORS + Zinc distribution to observe in real time the quality-of-service organization and delivery, the availability and management of inputs, compliance with operational procedures, and the identification of localities and households not covered by vitamin A capsule distribution agents.

Independent monitoring of the PECS survey will be implemented concurrently with the conduct of the PECS survey, within a maximum of four (4) weeks after one of the two campaigns, to ensure continuous quality control of enumeration, household data collection, and supervision processes, while limiting recall bias.

The overall monitoring system aims, on the one hand, to evaluate the performance of vitamin A supplementation (VAS) campaigns and ORS + Zinc distribution and to verify the quality and compliance of the implementation of activities during the campaign, and, on the other hand, to ensure the quality control of the post-event coverage survey (PECS) data in order to guarantee their reliability, consistency, and quality. This system also aims to ensure that all processes comply with World Health Organization (WHO) standards and Helen Keller International requirements, particularly regarding campaign implementation and data quality.

We are looking for an NGO or consulting firm to support Helen Keller’s teams in the country in carrying out independent monitoring activities during the campaigns and subsequent coverage surveys.

The two campaigns are likely to take place in May and November 2026. Once the contracting organization has completed the independent monitoring of the May 2026 campaign, its performance will be evaluated and based on this performance, a second monitoring assignment may or may not be awarded to this consulting firm for the second half of the year.

The firm will be responsible for preparing independent monitoring, including adapting tools, recruiting, training, and supervising field monitors, collecting data, analyzing data, conducting the independent monitoring itself, preparing a general narrative report on the independent monitoring, and preparing a PowerPoint presentation for the 5 states.

The purpose of this consultation is to independently monitor Vitamin A distribution activities across all regions supported by Helen Keller Intl: (Adamawa, Benue, Ebonyi, Nasarawa & Taraba). And conduct data-collection quality control for the coverage survey.

The selected consulting firm(s) will work closely with the Helen Keller International team and the Technical Steering Committee.

Applications must include independent monitoring of two campaigns and independent quality control monitoring of a coverage survey.

Methodology and sampling for independent monitoring (VAS campaign and PECS survey)

1. Independent monitoring of campaigns (first and second rounds in 2026)

The objective of independent monitoring of vitamin A supplementation (VAS) campaigns and ORS + Zinc distribution is to provide an objective, independent, and real-time assessment of campaign implementation to evaluate the quality of organization and service delivery, quickly identify coverage gaps, and support operational decision-making for continuous improvement of campaign performance.

This system aims in particular to verify whether the targeted households and children have actually been reached by the distribution teams, to document the factors that influenced coverage (accessibility, availability of inputs, social mobilization, organization of teams), and to ensure that activities comply with national standards and procedures, as well as with World Health Organization (WHO) standards and Helen Keller International requirements.

Methodology for implementing independent monitoring of the campaign

Independent monitoring of vitamin A supplementation (VAS) campaigns is conducted simultaneously in 5 states (Adamawa, Benue, Ebonyi, Nasarawa and Taraba) and ORS + Zinc in Bali LGA of Taraba State during the campaign to provide an objective, real-time assessment of household coverage and the quality of implementation. It begins on the second day of the campaign and continues until the last day, which generally spans four (4) to five (5) days. As highlighted above, some Wards in Benue and Ebonyi are excluded from the VAS campaign because of routine implementation happening in those Wards.

The supervisors of the independent monitors must be present in the field the day before the campaign begins to participate in preparatory meetings, distributor training sessions, and coordination meetings with health district officials. On the first day of the campaign, they will support operational planning, ensure activities get off to a good start, and prepare for the effective implementation of independent monitoring, which will begin on the second day.

From the second day of the campaign, corresponding to the first day of independent monitoring, the consultant will implement both household-level and non-household independent monitoring.

a) Household monitoring

Independent monitoring at the household level aims to objectively verify the effective coverage of eligible children by vitamin A distribution teams, quickly identify households and localities that are not covered or are only partially covered, and provide operational information to enable immediate corrective action during the campaign.

The monitoring system is part of the outreaches distribution strategy implemented during vitamin A supplementation campaigns, relying on teams of two (2) distributors responsible for visiting all targeted households. However, experience has shown that, despite rigorous advance planning, operational constraints can arise, including stockouts of inputs, scorecards, or other essential supplies; discrepancies between the population data used for planning and the reality on the ground; and the omission of hard-to-reach communities. In this context, independent household-level monitoring is an essential mechanism for quickly detecting these malfunctions, triggering timely corrective action, and enhancing the effectiveness, quality, and equity of the campaign.

To this end, a standardized field-monitoring methodology will be implemented, enabling rapid, structured collection of information at the household level in accordance with WHO recommendations for independent campaign monitoring.

During the three (3) to four (4) days of independent monitoring, each monitor will be required to cover four (4) localities per day, at a rate of two (2) localities per health facility (health area), for a total of 12 localities and at least 120 households visited per monitor over three days. In each locality visited, the monitor will survey at least ten (10) households, with the option to extend the sample to fifteen (15) households based on the results observed.

If, among the first ten (10) households visited, the monitor identifies at least three (3) households with at least one eligible child who has not received vitamin A, the locality will be immediately declared insufficiently covered.

If the monitor identifies one (1) or two (2) uncovered households among the first ten households, he or she must complete the sample by visiting five (5) additional households, bringing the total to fifteen (15) households. If, after visiting fifteen households, at least three (3) households have children who have not received vitamin A, the locality will also be declared insufficiently covered.

Any locality identified as having insufficient coverage must be immediately reported to the relevant health officials so that corrective action can be taken quickly, including targeted re-visits or the return of distribution teams to the area concerned.

Independent household monitoring will be implemented in 5 states of the country, covering selected health districts and selected localities, selected in accordance with the defined monitoring methodology and the country’s program priorities.

b) Non-household monitoring

As part of independent non-household monitoring, monitors deployed at the health district level will select at least two localities in each district where children have been suspected of receiving vitamin A supplementation outside the strict outreaches framework, particularly during activities carried out in markets, mosques, streets, or other public places frequented by children accompanied by their parents or guardians.

In these localities, the monitor will conduct rapid monitoring of at least ten (10) caregivers encountered opportunistically in the relevant public spaces (markets, places of worship, streets, etc.), checking whether eligible children have received vitamin A during the campaign. Depending on the results, the sample may be expanded to fifteen (15) caregivers.

If, among the first ten (10) caregivers interviewed, the monitor identifies at least three (3) caregivers with at least one eligible child who did not receive vitamin A, the locality will be immediately considered insufficiently covered. If one (1) or two (2) uncovered caregivers are identified among the first ten caregivers, the monitor will complete the survey by interviewing five (5) additional caregivers, bringing the total to fifteen (15) caregivers. If, after surveying fifteen (15) caregivers, at least three (3) caregivers with children who have not received vitamin A, the locality will also be declared insufficiently covered.

Any locality identified as having insufficient coverage must be reported to the relevant health officials immediately so that corrective action can be taken quickly, including targeted outreach or redeployment of distribution teams to affected areas.

In summary, each monitor will carry out the following activities:

The monitor will cover four (4) localities per day as part of the independent monitoring activities.
In each of the four localities, the monitor will conduct a household survey, for a total of four (4) household surveys.
Among these four localities, the monitor will also conduct non-household monitoring in two

(2) localities, resulting in two (2) non-household surveys.

踱踰踲踳 Overall, each monitor will therefore conduct:

4 household surveys, and  2 non-household surveys.

The methodology for household and non-household monitoring applies also to ORS + Zinc distribution in Bali LGA of Taraba State.

 Criteria for selecting sites for monitoring

The selection of health districts, health areas, and localities for monitoring will be based on a risk- and representativeness-based approach, in line with World Health Organization (WHO) recommendations for independent campaign monitoring. The selection criteria will include, but are not limited to, geographical remoteness and accessibility, urban, peri-urban or rural context, historical performance of previous campaigns, reported coverage levels, population density and mobility, and the existence of known operational constraints (areas that are difficult to access, security contexts, border areas, or areas with high mobility). The consulting structure must clearly and justifiably describe the approach used to select the sites to be monitored, ensuring balanced coverage of the different contexts and operational added value for real-time decision-making.

2. Independent monitoring for quality control of the post-campaign coverage survey of vitamin A supplementation in the second half of 2026

As part of efforts to improve the quality, reliability, and credibility of data from the post-event coverage survey (PECS), independent monitors will be mobilized to ensure quality control of the post-campaign coverage survey on vitamin A supplementation. The PECS survey will be conducted in a total of two hundred and four (204) clusters selected using a size-proportional sampling (SPS) method. The quality control of the post-campaign coverage will not happen in Benue and Ebonyi states; however, it will happen for ORS + Zinc distribution in Bali LGA of Taraba State. PECS will happen in Benue and Ebonyi after the second round of the campaign, and the consultant should also cost for quality control.

Eligibility Criteria and Intervention-Specific QC

Quality control will be carried out in Adamawa, Nasarawa and Taraba (Stratum 1) and Bali LGA of Taraba State (Stratum 2)

For PECS quality control, the consultant must ensure clear distinction between:

Vitamin A Supplementation (VAS): children aged 6–59 months
ORS + Zinc distribution: children aged 0–59 months QC verification must ensure that:
The census includes all children 0–59 months in Bali LGA.
VAS coverage is assessed only among 6–59 months.
Zinc coverage analysis reflects the full under-five population (0–59 months).

Household enumeration

For quality control purposes, approximately twenty percent (20%) of the clusters, or forty-one (41) clusters, will be selected at random from among the clusters surveyed, ensuring that the regions covered and the types of residence (urban and rural) are representative. This independent monitoring system aims to objectively verify the quality of the enumeration, household data collection, and supervision, and to ensure that the data produced complies with the methodological standards of the World Health Organization (WHO) and the requirements of Helen Keller International.

Audio listening interviews conducted by the PECS consultant

In addition, the independent monitoring team will be responsible for conducting a systematic audio audit of the household interviews conducted by the teams of the consultants in charge of the PECS survey, to strengthen the quality control of data collection. To this end, at least two (2) household interviews per PECS consultant interviewer will be re-listened to in each of the eighty-six (86) clusters surveyed. As a guide, when two (2) interviewers are deployed per cluster by the PECS consultant, the quality control system must cover at least four (4) audio recordings per cluster, i.e., an estimated total of three hundred and forty-four (344) audited household interviews.

c) Data Quality Audit (DQA)

To ensure the quality, reliability, and credibility of the post-event coverage survey (PECS) results, a structured data quality control and assurance system will be implemented throughout the collection and analysis process. This section describes the minimum requirements and guiding principles for quality control that consultants must incorporate and follow in their technical proposal, in accordance with PECS standards and Helen Keller International requirements.

During the enumeration, the consulting firm is invited to propose and implement a methodological and operational approach appropriate for data collection, including, but not limited to, mechanisms to ensure the completeness, reliability, and quality of the data collected:

A methodological and technical approach adapted for the use of GPS coordinates of clusters and/or shapefiles for the delimitation and mapping of clusters. The proposed approach should enable the development of accurate and usable maps, facilitating comparisons with the PECS team’s data. The consulting firm is encouraged to propose innovative technical solutions to enhance the accuracy, reliability, and traceability of cluster delineation and data comparability.
An approach to monitoring the enumeration of households by cluster, allowing the number of households enumerated to be compared with the estimates of the relevant national statistical institution. The proposed approach should enable the identification of any discrepancies (underestimates or overestimates), improve the quality of enumerators’ and supervisors’ work, and contribute to proper cluster delimitation and a comprehensive household count.
An approach that allows, at the end of the enumeration, the production of maps by enumeration area (EA), illustrating the spatial distribution of the households counted, for validation by the Helen Keller International coordination team before the start of the household survey. The proposed approach should ensure the consistency, completeness, and quality of the census, a progressive validation approach to the census, based on the projection and analysis of the GPS coordinates of the households counted as the survey progresses, in order to enable continuous verification of the spatial coverage of the clusters, to identify early on any areas with insufficient coverage or anomalies in the count, and to validate the completeness of the count before the final selection of households to be surveyed.

The quality control consultant is invited to propose and implement an innovative and appropriate approach to enhance the quality, reliability, and real-time monitoring of the data collected during the household survey by the PECS consultant. As such, the proposed approach may include, but is not limited to:

Quality control integration must include systematic audio monitoring of at least two (2) interviews per interviewer and per cluster, i.e., a minimum of four (4) audio recordings per cluster.
The integration of interview verification mechanisms, such as recording interview sequences or any other equivalent mechanism, assessing the quality of household data collection.
Daily monitoring of data quality indicators, with regular sharing of results with the Helen Keller International team and the survey steering committee during debriefing sessions.
The implementation of a daily monitoring dashboard covering the main targets of the survey (census, household survey, district levels, health workers, and community health workers), enabling operational management of data collection.
Production of daily collection reports, including discrepancies observed during quality control activities and corrective measures implemented.
Proposing an analytical approach compatible with the tools used by Helen Keller International, particularly for monitoring data collection, quality control, data cleaning, weighting, and analysis, and providing all the scripts or analytical programs used.

In addition, the consultant in charge of quality control will be required to propose and implement a structured approach to data triangulation to strengthen the robustness, consistency, and credibility of the PECS survey results. This approach should include, but not be limited to:

Triangulation of the data from the census conducted by the quality control consultant with that produced by the PECS consultant, in order to verify the completeness of the household listings, the consistency of the numbers counted, and the conformity of the sampling frames used.
Triangulation of household data collected by the PECS consultant with secondary data available from the relevant national statistical institution (population estimates, demographic structures, average household sizes), with a view to identifying any discrepancies, biases, or inconsistencies.

The results of these triangulation exercises should be clearly documented, analyzed, and included in quality control reports, along with operational recommendations to improve data quality, correctly interpret coverage results, and align estimates with official national sources.

Consultants must describe in detail their technical and methodological approach, as well as any innovative solutions proposed to improve efficiency, traceability, and overall quality of data collection and analysis.

General responsibilities of the consultant

The consulting firm will be responsible for preparing, implementing, analyzing, and reporting on the independent monitoring of vitamin A supplementation (VAS) campaigns, ORS + Zinc Distribution and the independent quality control monitoring of the post-event coverage survey (PECS), based on data collected in the monitored localities and in the PECS survey clusters.

i) Preparation phase

The consulting firm will be responsible for the complete methodological design of the independent monitoring of the vitamin A supplementation campaign and the quality control of the PECS survey, including the development of the protocol, the selection of health areas and localities to be monitored during the campaign, and the development of the data collection and training tools necessary for the implementation of campaign monitoring and PECS survey quality control.

Development of the protocol and tools

Drafting and finalization of the study protocol covering all aspects (households, health area, monitor, distributor, enumeration). Development of quantitative questionnaires in French (and translation into local languages if necessary). Validation of these documents by Helen Keller Intl prior to fieldwork.

Sampling and survey plan

The consultant will work closely with Helen Keller International to select the health areas and localities to be monitored as part of the independent monitoring of vitamin A supplementation campaigns.

As part of the PECS survey quality control, the consultant will assist in the selection of eighteen (18) to twenty (20) clusters for enumeration quality control, as well as the selection of households whose interviews will be subject to an audio audit, at a rate of at least four (4) households per cluster. The consultant will obtain GPS coordinates and/or shapefiles for the clusters from Helen Keller International and use this data to develop operational mapping tools to ensure precise delineation of the intervention areas and effectively guide field teams. Provide a forecast file of the expected number of households per cluster (based on available census data) and compare these forecasts with the number of households counted by the interviewers to identify any under- or overestimates and remedy them promptly.

ii) Training and collection phase

The consulting firm will be responsible for training and deploying the field teams necessary to carry out independent monitoring of the campaign and quality control of PECS, including monitors, supervisors, quality controllers, and, where applicable, drivers.

Training data collection teams

It will organize and conduct comprehensive training for all collection staff, covering in particular:

The objectives of the study and the approved protocol.
Mastery of questionnaires and interview guides (quantitative and qualitative) ;  Interview and observation techniques in the field.
Use of mobile devices and the SurveyCTO platform.
Ethical principles of research, including informed consent, confidentiality, and data protection.  Data supervision and quality control procedures.

To ensure the methodological robustness and operational effectiveness of the independent monitoring mechanisms for the vitamin A supplementation campaign and the quality control of the post-event coverage survey (PECS), pilot phases will be implemented before data collection begins in the field.

Independent monitoring of the vitamin A supplementation campaign and ORS + Zinc distribution: a pilot phase of independent monitoring of the campaign will be carried out on a limited sample of localities to test the operational field system, including data collection tools, supervision procedures, data transmission mechanisms, and the results reporting system. The lessons learned from this pilot phase will enable adjustments to be made, if necessary, to the tools, procedures, and operational organization before the full deployment of independent monitoring during the campaign.
Post-event coverage survey (PECS) quality control: A pilot survey specifically for PECS quality control will also be conducted on a limited number of clusters to test the entire quality control system, including enumeration, household data collection, audio audits of interviews, supervision, and data transmission. ‘s results from this pilot phase will be used to refine the tools, quality control protocols, and implementation procedures before the actual start of PECS survey quality control activities.

The consulting firm will also be responsible for all training activities for interviewers and supervisors, which must be organized in person. The Helen Keller International team may participate in certain key activities, including training and supervision sessions.

Data collection phase
1. The consultant will be responsible for planning and supervising field activities for the independent monitoring of AVS campaigns and quality control of the PECS survey. This includes developing itineraries and schedules for covering selected health areas, localities, and clusters; mobilizing transportation appropriate to the context; managing field teams; and providing the necessary equipment (smartphones/tablets configured with validated SurveyCTO forms, external batteries, support materials). The consultant will be responsible for ensuring that the data collected is synchronized daily with Helen Keller International’s SurveyCTO server.
1. During the independent monitoring of vitamin A supplementation (VAS) campaigns and ORS + Zinc distribution, the consultant will be responsible for planning, deploying, and supervising teams of independent monitors to assess in real time the quality of campaign implementation, effective household coverage, availability and use of inputs, and compliance with operational procedures. The consultant will be responsible for collecting and analyzing field data on a daily basis, quickly identifying localities or households that are not covered or are insufficiently covered, documenting operational difficulties (stockouts, mobilization or accessibility issues), and promptly sharing this information with health authorities and the Helen Keller International team to enable corrective actions to be taken, including targeted re-raiding. The consultant will also provide ongoing supervision of monitors, monitor data quality, produce daily reports, and prepare a consolidated independent monitoring report presenting the main results, corrective actions taken, and operational recommendations for improving future campaigns, in accordance with WHO standards and Helen Keller International requirements.
1. The consultant will be required to set up a real-time supervision and quality control system, including regular field visits by the head of mission and/or coordinators to supervise teams, anticipate operational difficulties, and provide rapid solutions. This system must ensure the effective implementation of the planned quality control measures, in particular the recounting of approximately 20% of the selected clusters (i.e., as an indication, 18 clusters) to verify the completeness and consistency of the household list, as well as the performance of a systematic audio audit of household interviews, covering at least four (4) interviews per cluster, selected from the recordings made by the PECS consultant’s teams. All anomalies and discrepancies found must be documented in a quality control log, accompanied by the corrective actions implemented. The consultant must also set up a daily monitoring dashboard of the main collection and quality indicators for all parts of the survey, accessible to the steering team to enable continuous, real-time monitoring.
1. The consultant will be responsible for rigorous data management throughout the collection process. As such, they will be required to extract raw data daily from Helen Keller International’s SurveyCTO server and import it into Stata to perform automated quality checks. They will ensure the completeness and regularity of synchronizations performed by field teams, quickly identify any anomalous, inconsistent, or missing data, and promptly communicate these findings to the relevant supervisors for correction. The consultant will also be responsible for ensuring data security and confidentiality at all stages of the process, including storage on secure media, controlled access management, and anonymization of sensitive data in files transmitted for analysis.
Analysis phase

The consulting firm will be responsible for cleaning, processing, and analyzing the collected data.

Conduct a comprehensive analysis of the data collected, in accordance with the validated analysis plan. Generate results for each component (coverage statistics, data quality indicators, logistical findings, etc.) and interpret these results in a cross-referenced manner to answer the study questions. Draft the expected deliverables, including:

A report on the training of interviewers and the pilot study (describing the training process, adjustments made after the pilot study, and the teams’ level of preparedness).
Interim reports or briefings during data collection, including a quantitative data collection completion report summarizing the difficulties encountered and solutions implemented.
Independent monitoring report on the vitamin A supplementation campaign: For each campaign phase, the consultant will produce an independent monitoring report presenting the results of field observations in a structured manner. The report will document the quality of the campaign’s implementation, including household coverage, the organization of distribution teams, the availability and management of inputs, compliance with operational procedures, and the localities with insufficient coverage and the corrective actions implemented (mopping up, targeted returns). It will include an executive summary, a quantitative analysis of key indicators, a summary of daily feedback provided to health authorities, and operational recommendations aimed at improving the performance and equity of future campaigns. The same applies to ORS + Zinc Distribution. It is expected that a separate monitoring report is generated for ORS + Zinc Distribution in Bali LGA of Taraba State.
Independent quality control monitoring report for the PECS survey

The consultant will produce a specific quality control report on the PECS survey, consolidating the results of the recount and audio audits of household interviews conducted by the PECS consultant’s teams. This report will analyze the quality, consistency, and reliability of the data collected at each stage of the survey, highlight discrepancies between different data sources (count, household survey, audio audits, secondary data), and document the corrective measures taken. It will include an executive summary, a detailed analysis of the quality control system’s results, and technical recommendations to strengthen procedures, supervision, and data quality for future PECS surveys. Independent quality control will be conducted for ORS + Zinc distribution in the implementing LGA.

Technical appendices, including cleaned and consolidated databases in Stata (.dta) format covering all components, all analysis scripts (do files) used, data dictionaries (codebooks), and any other relevant documents (e.g., finalized interview guides, checklists used). Transcripts of qualitative interviews will be made available to Helen Keller Intl if required for further consultation.

In carrying out these tasks, the consultant will need to demonstrate excellent coordination with Helen Keller Intl’s technical research team and local district health authorities. Regular status updates will be provided to ensure the survey is conducted in accordance with the protocol and to facilitate local stakeholders’ ownership of the results and recommendations.

v) Feedback and reporting phase

The consulting firm will be responsible for producing all expected deliverables, including the training report, data collection report, and final survey report. The final report will include a clear executive summary and operational recommendations that stakeholders can use directly. The consulting firm will also support the organization in conducting a workshop to present the results to the institutional actors and partners involved.

All data collection tools will be provided by Helen Keller International in French. The consulting firm will ensure its translation into the languages of the local communities concerned, in close collaboration with Helen Keller International. It will be responsible for contextualizing and finalizing the tools, ensuring their consistency with the study objectives and strict compliance with validated methodological and ethical protocols.

Note

All questionnaires will be digitized using the SurveyCTO platform. The selected consultants must have their own SurveyCTO account to carry out all the preparatory steps for the actual data collection, including setting up and testing the tools, conducting the pilot survey, and testing between the end of the training and the start of the collection. Once the tools have been finalized and validated, they must be sent to Helen Keller International for uploading to the organization’s centralized server, which will be used for both the pilot survey and the main survey.

During the collection phase, the consultant will have “External Viewer” access to Helen Keller International’s SurveyCTO server. This access will allow for daily database downloads and real-time monitoring of data quality. The consultant must demonstrate proficiency in using the server, labeling tools, and data export procedures for analysis using Stata software.

The consultant must designate a technical expert specifically responsible for configuring SurveyCTO forms and monitoring data quality via the server. The consulting firm is expected to have at least two proven experiences combined and joint use of SurveyCTO and Stata for coverage surveys or similar studies.

The consulting firm will also be responsible for providing data collection equipment, including smartphones or tablets for each field team. This equipment must be suitable for intensive use, function effectively in a variety of field contexts, and have been tested during the pilot survey to ensure the reliability and quality of the data collected.

Throughout the data collection process, the consultant will be required to implement a daily data quality monitoring system based on a set of key indicators to quickly identify any anomalies or inconsistencies. The results of this monitoring will be communicated daily to the Helen Keller International team to ensure ongoing transparency of the data collection process.

Finally, regular debriefing meetings must be organized between the consultant, the Helen Keller International team, and the technical committee that will be set up by Helen Keller to monitor the survey in order to review the progress of activities, discuss any difficulties encountered, and, if necessary, adjust data collection strategies with the aim of ensuring compliance with data quality, reliability, and accuracy requirements
