1) Training of Fieldworkers:

Training is planned and executed at the centre ie at Vadu HDSS every six months before the data collection round begins. Five days training session is conducted and every training session is evaluated by both the trainees and trainers. Trainers complete daily evaluation by asking questions in order to identify problems that trainees had experienced during that particular day’s training. Areas that needed re- training are revisited the following day. At the end of the training moc interviews are conducted by the trainees.

Survey:

The data collection approach revolves around the use of a team of Field Research Assistants and Field Research Supervisors. The team is assigned a fixed number of EAs to enumerate. The team works together in each sampled EA and moves to the next one, once the targeted EA had been completed. The advantage of this method is that the supervisor is in daily in contact with the team, which improves the quality of the data collection during fieldwork.

Supervisors go to the FRA who have completed the interview and immediately check the questionnaire for errors, consistency and completeness. Where errors are found, the FRA is sent back to the household to correct the information that had been recorded previously. If the supervisors are satisfied, they sign off the questionnaire and store it in a safe place. Supervisors do the same for all the members of their team until the EA had been completed. The team then moves to another selected EA.

The interview is conducted face - to -face which takes approximately 15 - 30 minutes each and this entire process takes around 5 months for every round.
