Congratulations to IFPRI-Bangladesh on showcasing Bangladesh's experience in evidence-based nutrition research during the recent roundtable with the visiting delegation from the Government of Canada.
Research has the greatest impact when it informs policy and practice, and studies such as the Transfer Modality Research Initiative (TMRI), Agriculture, Gender and Nutrition Linkages (ANGeL), and the ongoing JIBON study continue to generate valuable evidence on improving maternal and child nutrition through integrated, scalable interventions.

At DATA, we are proud to have partnered in the design and implementation of all these landmark studies. JIBON was the latest addition to DATA’s portfolio of surveys studying conditional cash transfers and one of many collaborations between research bodies and DATA funded by Gates Foundation.

JIBON was a very complex survey designed to track pregnancy in target locations from conception to child delivery. It followed a more rigorous listing process where we targeted women of select ages with one or less children for recruitment. Then these women were detected for their natural conception using full time assigned detection workers in the sampled areas assigned by DATA. Once child is conceived these mothers were recruited for surveys in every trimester. The interviewers were assigned by DATA, and after delivery the baby’s birth weight and head-circumference were measured with-in 72 hours, by another specialized anthropometry team also trained and managed by DATA. This was a complex survey because of the varying nature each pregnancy and timeline of each pregnancy. So these were 4000+ unique cases that was surveyed in four rounds from conception to delivery, and even more were listed during census. This is truly one of DATA’s proudest accomplishments.

For DATA, a consultancy firm supporting research, it truly adds motivation and purpose when we see our data reach conversations of policy level impact. Supporting rigorous field operations, high-quality data collection, and robust data management for nationally significant research has been both a privilege and a responsibility. Seeing these collaborative efforts contribute to discussions with development partners and policymakers reinforces the importance of investing in quality evidence.

Congratulations to IFPRI and all collaborating partners for advancing research that helps shape a healthier and more food-secure Bangladesh. We look forward to continuing our collaboration in producing evidence that drives meaningful development outcomes.

Congratulations to IFPRI-Bangladesh on its continued contribution to evidence-based policymaking in Bangladesh and its participation in the 10th CGIAR Advisory Committee (CAC) Meeting.

Over the decades, IFPRI's research has played an important role in shaping national conversations around food security, nutrition, agricultural transformation, and rural development. The policy impact of landmark initiatives such as the Bangladesh Integrated Household Survey (BIHS), the Transfer Modality Research Initiative (TMRI), and the Agriculture, Gender and Nutrition Linkages (ANGeL) project demonstrates the value of sustained investments in high-quality research and strong partnerships.

At DATA, we are proud to have facilitated the implementation of all three of these important studies alongside IFPRI and other partners. From survey design and field operations to data collection, data management and quality assurance, it has been a privilege to contribute to the evidence base that informs policies and programs affecting millions of Bangladeshis.

The success of the survey projects mentioned above is an example of DATA’s collaborations beyond the contract. Even today DATA clarifies queries from these projects to new researchers and analysts because we at DATA believe research is not confined within boundaries of a contract. It requires long term collaboration and a shared enthusiasm for development.

We congratulate IFPRI-Bangladesh on its achievements and look forward to continued collaboration in generating rigorous evidence for a more resilient, productive, and sustainable future for Bangladesh.

We are pleased to announce the successful completion of Round 0 (R0) and Round 1 (R1) of the World Bank's Mode Effects and Climate Adaptation Survey in Bangladesh.

What began as an ambitious study examining differences in data quality between phone and face-to-face surveys evolved into a highly sophisticated experimental research design. As the project progressed, multiple layers of randomization and experimental procedures were introduced to better understand how survey mode, timing, and field implementation affect data quality and measurement outcomes.

The R0 survey consisted of comprehensive face-to-face interviews with 1,500 households across 50 Primary Sampling Units (PSUs), with two respondents interviewed from each household. In R1, the sample was split equally between phone surveys (750 households) and face-to-face surveys (750 households). To further strengthen the experimental design, interview timing was also randomized, allowing researchers to examine whether the time of day influences survey responses and data quality.

The greatest challenge of the study was not simply conducting two consecutive survey rounds—it was conducting them simultaneously. DATA implemented an innovative rolling field strategy, completing the R0 survey in three PSUs while simultaneously conducting the R1 survey in those same PSUs within a nine-day window before moving on to the next batch of locations. Through this process, DATA successfully completed both R0 and R1 across all 50 PSUs.

The survey was conducted across diverse geographical settings in Sunamganj, Satkhira, Sirajganj, and Dhaka. A dedicated team of 36 field officers carried out the data collection effort, supported by specialized monitoring and audio-auditing teams to ensure the highest standards of data quality and research integrity.

Before deployment, every member of the field team underwent an intensive month-long training program, preparing them for the complex protocols and rigorous quality assurance procedures required by this groundbreaking study.

This achievement reflects the dedication, professionalism, and resilience of our field staff, supervisors, monitors, data management team, and project leadership. We are proud to have partnered with the World Bank on a study that is expected to contribute important evidence to the growing global literature on survey methodologies, climate adaptation research, and the future of data collection in developing countries.

As we celebrate this milestone, DATA is already gearing up for Round 2 (R2) of the survey. The next phase will continue to build on the innovative research design and generate valuable insights into survey methodologies and climate adaptation measurement. We look forward to sharing more updates on R2 and the progress of this exciting project in the coming weeks.

Congratulations to the entire DATA team for another successful milestone in advancing high-quality development research.

We are pleased to share the successful completion of the household listing exercise for the World Bank’s Mode Effects and Climate Adaptation Study, conducted in collaboration with World Bank.

Over the course of this operation, our dedicated field team of 36 members covered more than 60 Primary Sampling Units across four districts—Sirajganj, Satkhira, Dhaka, and Sunamganj. Originally planned as a 15-day census activity for participant recruitment, the exercise was strategically extended in urban areas to account for potential attrition in upcoming survey rounds.

Using digital mapping tools to accurately identify enumeration boundaries, our teams conducted a comprehensive listing of 6,000+ households. From this listing frame, approximately 1,500 participants will be randomly selected for the main quantitative survey phases.

The entire process was efficiently managed using the Survey Solutions platform, ensuring high-quality data collection, real-time monitoring, and seamless coordination between field and central teams. The listing exercise started on 26 March 2026 and ended on 13 April 2026

This milestone reflects the strength of DATA’s field operations and its continued commitment to delivering rigorous, large-scale survey solutions in partnership with global institutions.

We are pleased to share the successful completion of a qualitative research project in collaboration with the World Bank .
The survey name is "Bangladesh Survey Mode Effects and Climate Adaptation Methodological Study".

The study has two components : Survey Mode Effects and Climate Adaptation. The qualitative component of the study will comprise four types of interviews : Focus Group Discussions (FGDs), two types of Cognitive Interviews (Mode Effects & Climate Adaptation), Mental Model Interviews (MMIs).

Each interview types serves a distinct purpose and covers different themes. In particular, Mental Model Interview will explore how households and individuals perceive and think about climate risk - especially flood risk. Focus Group Discussions will be used to understand how individuals perceive different interview modes - specifically face-to-face versus phone interviews. Cognitive Interviews are used to assess the adequacy and clarity of survey questions and to refine the questions as needed as preparation to a quantitative round. The cognitive interviews will cover both the questions designed to disentangle survey mode effects and those related to climate risk perceptions, impacts and adaptation which will later be incorporated into the quantitative survey.

The training commenced on 18 January 2026. After pilot testing the qualitative questionnaires in rural and urban contexts in Dhaka on the 24th and the 28th of January, the main fieldwork was set in motion in the first week of February. The main qualitative field study was conducted in Satkhira, Sirajganj, Sunamganj and Dhaka; successfully concluding this round on 8 February, 2026.

DATA is pleased to share an ex*****on update from the field under TMRI-2026, following the completion of our intensive training and CAPI preparation sessions. Since 2 December, 2025 our field operation has been running actively in Kurigram and Rangpur, and the follow-up survey will continue for approximately 1.5 months with full adherence to the protocols established during training.

A total of 75 team field officials have been deployed to the assigned locations (five upazilas)—the team has now transitioned smoothly into full-scale ex*****on.

From the first day of deployment, male and female enumerators have been conducting interviews professionally within their targeted areas, completing the assigned quantitative modules with accuracy and care. The survey includes the household questionnaires for male, female, and adolescents, and each module is being administered exactly as designed maintaining checks emphasized during training. The Identification and Household Roster components are being handled with particular attention, ensuring every household member is listed properly before proceeding into the respective questionnaires, and that the data structure remains consistent across cases.

Enumerators are confidently navigating the CAPI system module-by-module, while supervisors provide. Daily supervision mechanisms are in place to confirm that field procedures match the standard operating protocols practiced in training, and that any issues are resolved immediately through guidance and correction. The supervisors are also in charge of conducting community surveys with local community experts.
Supervisors and monitors are maintaining daily observation and monitoring routines, supporting enumerators with spot-checks, review discussions, and real-time feedback to safeguard the overall reliability of the follow-up survey.

The team is working with strong enthusiasm, professionalism, and coordination. We are on track to reach 2000+ follow up households, and complete 250 communities. We remain committed to maintaining high-quality survey standards throughout the TMRI-2026 operation and will continue to share progress updates as we reach the conclusion of TMRI 2026 survey.

DATA is pleased to share a comprehensive update on the completion of our intensive enumerator training program for the TMRI 2026 – 12-Year Follow-Up Survey. Over the last month, our team conducted one of the most extensive and structured training cycles in DATA’s history—spanning 28 days, involving 85 enumerators.

The training began with combined male–female sessions covering foundational modules such on household identification and formation, along with an overview of the project’s background dating back to TMRI’s inception in 2012.

Recognizing the depth and complexity of the questionnaires, male and female enumerators were later separated to focus on modules specific to their respective household questionnaires. During this period, the male team covered modules only in the male questionnaire while the female team completed modules specific to the female questionnaire.

The team transitioned to CAPI-based training, following detailed paper explanations to build mastery of the questionnaire flow. This hybrid approach was aimed to strengthen both conceptual understanding and technical precision. The early days also included trial assessments focused on the household roster to identify common challenges and prepare enumerators for formal ranking assessments.

There were days dedicated to structured peer-to-peer mock practices, where enumerators acted both as interviewers and respondents using the full CAPI system. Their delivery skills were assessed to prepare them for later evaluations. The following days were used to complete all common modules and introduce the Adolescent Questionnaire, including a detailed orientation on cognitive testing procedures.

A major milestone came when enumerators administered cognitive tests on 42 adolescents, followed by analytical feedback sessions. These exercises continued with even greater intensity later in the training. On Day 18, DATA set a new internal record by bringing in 81 adolescents for full-scale cognitive test standardization. This ensured strict adherence to SOPs and improved consistency across interviewers.

Anthropometry was a major focus throughout the training. Daily practice sessions led to the selection of Gold Standard enumerators. All team members were required to match measurements within 0.4 cm accuracy. This was reinforced again during correction and refresher exercises.

The last phase of training focused on detailed feedback from pretests, CAPI follow-through, refresher modules, supervisor/monitor assignments, logistics, equipment checks, and field protocol briefings.

On 30 November 2025, the full field team departed for their designated sites. Supervisors have already connected with local authorities, and DATA’s core monitoring team is on-site to oversee early operations.

This marks the successful transition from the training phase to full-scale field implementation for TMRI 2026. We are proud of our team’s dedication, professionalism, and resilience throughout this process.

Today DATA completed their 7th day of training for the 12 year follow-up survey: TMRI 2026. We started on the 28th of October. We have 85 field interviewers as participants for the enumerators’ training.

We are conducting weekly assessments to rank these 85 field officers. Till today we have conducted 2 assessments.

The Training started with combined male and female sessions for the first two days. There were brief short sessions on the general purpose of this survey and background of TMRI (starting from 2012) conducted by Zihad Bhai.

Identification Module and Household Roster needs to be completed by each enumerator; hence it was scheduled in the joint training sessions for male and female both. Even though modules on anthropometric measurements are only in the female questionnaire, it has to be implemented as a pair for each household. So both male and female enumerators need to be present during Anthropometric Training sessions. We are conducting practice Anthropometric Measurements every day for select enumerators on a rolling basis. We also have a practice and standardization sessions particularly scheduled for anthropometric measurement with mothers and 0-18 year old children.

On the 3rd day of training male and female enumerators were sent for separate training sessions. This will continue till the 9th day of training.

On the 5th day we started with CAPI training. Up until then the training sessions were covered in hardcopy (paper format) for enumerators understanding of the questionnaire. Day 5 and Day 6 were scheduled for a complete CAPI follow through of the entire questionnaire so far. This acts as a questionnaire recap as well. From the 6th day onwards the questionnaire is being explained on paper during the first half of the day and it will end with a follow-through on CAPI, where the trainer demonstrates how to complete the CAPI survey module by module.

Today we are continuing with separate training sessions for male and female enumerators. The day ended with a CAPI review of the questionnaire material covered today.
