The science

Rigorous psychometrics you can defend to any stakeholder.

Every IIOP career instrument is developed in line with the Standards for Educational and Psychological Testing (AERA · APA · NCME, 2014). Items are generated by expert panels, refined through cognitive interviewing, pilot-tested, factor-analysed, and continuously monitored for measurement invariance across gender, country and language.
