TNS NIPO is a Dutch survey agency. Together with Synovate (formerly Interview-NSS) and Surveys from Maurice de Hond (Peil.nl) it is one of the top three (political) survey agencies in the Netherlands.
TNS NIPO has a database of thousands of screened respondents. For each survey a selection is made from the database and submitted to the respondents. TNS NIPO's goal is to have the respondents surveyed once every six weeks.
TNS NIPO uses software from NIPO Software for its research surveys. The five following methods of research are used:
- CATI: Computer-assisted telephone interviewing
- CAPI: computer-assisted personal interviewing (by interviewer)
- CASI: computer-assisted self interviewing (respondent receives questions via modem)
- CAWI: computer-assisted web interviewing (respondent visit site)
- Qualitative research
The appropriate research form depends on the subject and target group.
