All Priority Research interviewers work to the MRS (Market Research Society) Code of Conduct and IQCS standards.

10% of any interviews will be followed up by telephone validation in order to maintain quality control. In the rare event that problems are found with an interviewer’s work, a 100% validation is carried out and interviews repeated where necessary.

Priority Research has developed specialised software which probes the quality of interviewers' data and immediately detects lax or poor quality work.
