Responsibility to minimize errors during the actual collection of data and ensuring that the sample and all related issues are properly executed

Pre-field……
• Interviewer Training before initiating any study
• Mock Calls / Pilot Tests conducted before start of fieldwork
During-field……
• Field Supervision / Spot Checks / Field Accompaniments
• Back Checks
Post-field……
• Logic Checks
• Random re-punch

• Supervisors who best understand the clients category are assigned to project
• Prior to fieldwork, a central briefing session is conducted for all interviewers and supervisors to explain Survey objectives & sampling procedure
• Pilot interviews are done with real respondents to ensure that they have achieved a thorough understanding of how the questionnaire should be administered. Pilot interviews are then eliminated from the sample.

• On a first assignment, each interviewer is accompanied by one of the fieldwork supervisors.
• A portion of each interviewer’s work is selected for checking. These quality checks are conducted to ensure that:
     ● Interviews were carried out with properly selected respondents and in accordance with the project’s instructions.
     ● Show cards and other materials to be shown to respondents were used correctly (face-to-face interviews).
     ● A number of questions, normally questions of fact rather than opinion, are re-asked to establish consistency of response.

• Through Editing process, a consistency & logic check is carried out on all the questionnaires to ensure that the questionnaires had been administered correctly
• After ensuring that the fieldwork is error free the date is punched into the computers.
• At this stage we ensure quality assurance by two methods:
     ● Validation Checks – Our punching program contains logical checks.
     ● 10% of the punched questionnaires from each fieldworker are randomly checked for possible punching errors. If any error spotted, a much lager proportion of questionnaires are then checked
