Training and Briefings:
Thorough briefing of methodology and questionnaire is followed up by mock interviews and trial calls
15% of interviews are accompanied by the supervisor, i.e. conducted under his/her supervision for both CAPI and PAPI
Both supervisors and back-checkers will back-check 15% of the interviews
Fraudulent interviewers will be dismissed and reported to the project manager; all their interviews will be pulled out and discarded
At the end of each day, for PAPI supervisors will edit all interviews conducted that day; incomplete questionnaires will be returned to the interviewer for completion and if the interviewer repeats the same mistake after being corrected by the supervisor, they will be dismissed.
At the end of fieldwork, editors of the Data Punching team will carry out plausibility checks on all questionnaires; questionnaires found wanting will not be captured and such questionnaires will be redone immediately.
