A survey is only as good as the people who ask the questions. Even a well-designed questionnaire produces poor data if enumerators read questions differently, skip consent or guess answers. Structured training is the cheapest way to improve data quality before the first household is visited.

Plan the training

Allow enough days for the length of the questionnaire, usually with classroom sessions followed by field practice. Keep groups small so every trainee gets practice and feedback. Prepare a training manual with every question, its purpose, definitions and examples. Questionnaires designed with our survey questionnaire design guide are easier to train.

What the training should cover

Purpose of the survey and how the data will be used
Informed consent, privacy and respectful behaviour
Question-by-question walk-through with definitions
Mock interviews in pairs, including difficult respondents
Using the tablet or app, saving and syncing data
Sampling rules, replacement rules and household listing

Test before the field

Run a short pilot in a village outside the sample. Compare answers from different enumerators for the same household and discuss differences. Use a written or practical test to select the final team; not everyone who attends training should go to the field.

Supervise and refresh

Supervisors should sit in on interviews, back-check a sample of households and review data daily. Share common errors with the whole team and hold short refresher sessions. Digital checks described in our CAPI data quality guide catch many errors early, and baseline studies benefit from the same team in the endline; see our baseline and endline survey guide.

Support for survey projects

ATTPL EMS designs surveys and trains and manages field teams. Staff onboarding and attendance can be handled in ATTPL HRMS, and programme design support is available from ATTPL Consultancy.

Frequently asked questions

How long should enumerator training be?

It depends on questionnaire length and complexity; plan classroom sessions plus at least one day of field practice and a pilot.

Should enumerators be tested after training?

Yes. A test and observed mock interview help select the most reliable enumerators.

What is a back-check?

A supervisor revisits a sample of households and repeats key questions to verify that interviews were done correctly.
