We follow the international Code of Marketing Research Practice which was developed by ESOMAR (European Society for Opinion and Marketing Research). CEM's founder, prof. Jan Jerschina, was an ESOMAR member for many years.



We belong to the Polish Association of Public Opinion and Marketing Research Firms (actually we are one of ten founders of the organization). One of the aims of this organization is to establish research standards and provide the means for the assessment of compliance with standards. For many years we have been subjected to a quality audit by OFBOR and each year we have received the Certificate of the Interviewer Quality Control Programme for CATI research.
