Scope of work
GTS seeks the services of a data collection organisation to conduct perception surveys with community members. The perception survey will be designed by Ground Truth Solutions following a co-design phase with community members (August 2026) and consultations with key actors. The coding and design of the survey will be done by GTS, with the selected data collection partner reviewing and providing suggestions and contextual inputs.

The findings from the survey will be used to generate insights and recommendations for civil society, humanitarian actors and donors to turn community insight into a more effective, coherent and relevant humanitarian response.

For our work in Sudan, the collaboration with the selected data collection partner will include a research scoping and design phase and a data collection phase.

In particular, we are looking for partners that can conduct the following activities.

1. Short research scoping & design phase

The selected data collection partner will contribute to defining the geographic scope of the research based on their presence and network, as well as provide insight on the accessibility and feasibility of conducting the research in specific locations across Sudan. The selected data collection partner is responsible for obtaining the necessary approvals for data collection and ensuring all appropriate measures are taken to ensure the safety of both enumerators and participants in the process.

The partner will conduct a short scoping phase, which is intended to provide insight and evidence to guide the selection of the most relevant target groups in selected locations and support in identifying a diverse cross section of the population. Along with GTS, the partner will contribute to the scoping phase through informal calls with relevant community actors and local NGO staff to help validate assumptions and contribute to the design of the survey.

2. Data collection phase

2.1. Quantitative Data Collection

The selected data collection partner will work with GTS on the design of a quantitative survey, support with sample design (see paragraph 2.3), conduct enhanced questionnaire testing, data collection (face-to-face surveys), and translation of any open-ended responses into English. The partner will:

a. Collaborate with GTS as requested in designing the survey tools (including translation of survey questions from English into relevant Sudanese Arabic and any relevant dialects).

b. Appoint, train (with GTS support), and manage a team of capable enumerators in different states in Sudan with appropriate education levels and experience in collecting quantitative data.

c. Ensure that enumerators have or are provided with materials and training they need to enable them to complete the assignment within the timeframe, including training on collecting data with SurveyCTO and the survey provided by GTS. GTS will provide a ‘Training of Trainers’ which will elaborate on the survey purpose, as well as remote data quality checks GTS will conduct.

d. Ensure a robust mechanism is in place for participants to file complaints or reports of enumerator misconduct and that enumerators understand and sign the GTS code of conduct.

e. Test the survey through both cognitive testing, in which a small number of interviews are carried out to test the understanding of certain questions in the survey, and pilot phase, in which all enumerators will be expected to record a small number of surveys. Training and interviews guides for the cognitive interviewing will be provided by GTS.

f. Ensure enumerators submit data in a timely manner and share with us brief daily updates where necessary on progress and/or challenges experienced in the field. This includes engaging with GTS’ feedback from daily quality checks and addressing any issues promptly.

g. Demonstrate that they can work safely and ensure the wellbeing of the enumeration team based on precedents and have a security protocol in place for any potential security incidents.

h. After data collection, ensure enumerators complete the enumerator feedback form to provide their feedback and experiences with the data collection process (anonymous).

i. After data collection, participate in a joint analysis session with GTS to discuss and validate the preliminary findings from the quantitative data.

Potentially (based on enumerator experience):

j. Conduct dialogue sessions with community members to share the findings of the research and ask for their reflections and input.

2.2. Quality Assurance for Quantitative Data Collection

We expect that quality assurance measures will be taken by our data collection partner to ensure that the data quality is of a high standard and accurately captures the opinions of people. In addition, GTS undertakes detailed data quality checks each evening of data collection, providing feedback in writing by the end of the day. These checks include evaluation of GPS data as well as evaluation of the time each interview takes and the content of responses to ensure adequate time and care is being taken for each interview. Additionally, we review the open-ended question responses and response patterns. We expect the selected partner to engage with feedback and deal with any issues that arise, which may include retraining of individual enumerators, and in some cases removal of enumerators who underperform.

In addition to co-developing enumerator training materials that reflect the enhanced questionnaire testing, the data collection partner will submit around 4 data points per enumerator for quality assurance prior the start of the data collection in each district according to the GTS format guidelines, which will not be part of the final data set. This entails the pilot testing.

2.3. Survey methodology and sample design

The selected data collection partner should be able to provide input and support on designing a sampling methodology and strategy based on available sources of information and mitigating any operating constraints in the different locations. The data collection partner will use the sampling approach defined by GTS to ensure randomisation, which will include requiring enumerators to visit specific GPS coordinates, and interviewing people at these coordinates within a given geographic boundary.

There will usually be around 30-35 questions, including some demographic questions. Questions will include multiple choice, binary/Likert scale and open-ended questions.

Sample size: 500 in each state, 6 states in total (3,000 interviews total). Interviews should be conducted with men and women above the age of 18, using a random sampling approach.

Target group

People in need living in Sudan, both people who receive aid (including recipients of aid and support from mutual aid initiatives) and those who don’t/haven’t, in selected district, 18+ years old (general population)

Geographic scope

To be defined with research partner

Survey mode and size

Face to face survey, 500 per state, 6 states total

Questionnaire length

30-35 questions

Deliverables

Verification and translation of survey tool.
Completion of cognitive testing and pilot stage – sharing feedback with GTS.
Completion of face-face data collection.
Submission of translated open-ended questions.
Participation in co-analysis session with GTS.
Participation in an end of data collection debrief, to discuss challenges faced and any research limitations to be included in the report.

Timeline

Data collection must be completed by 30 November 2026, and all deliverables submitted by 15 December 2026. A detailed work plan will be agreed upon at the beginning of the consultancy.

Do no harm and risk mitigation

The data collection partner must clearly indicate how the data will be collected in a responsible manner. It must ensure that all risks for respondents have been carefully identified along with mitigation measures to prevent any harm is caused to people directly or indirectly involved.
