Quality certification of research services

Confidence in market and opinion studies

The objective of the Standard ISO 20252 is to provide customers with a guarantee that the market, social or opinion study that they have contracted is carried out by a trusted organisation that implements the best control and follow-up practices to ensure compliance with this international standard.

The audit includes comprehensive monitoring of each phase of the research process: in managing technical work, gathering field data (in-person, over the telephone, online) or in managing and processing data.

This standard was developed through the active participation of the National Association of Market Research and Public Opinion Companies (ANEIMO), which endorses the sector's firm commitment to demonstrating the high-quality level in its service provision.
