Scientific background

Psychometric test publishing since 1991

Criterion was founded in 1991 by Richard Hunter who prior to this co-built the OPQ at SHL.

Psycruit's personality and ability assessments are based on rational model which means our assessments have the highest predictive validity of different psychometric tests.

  • Measuring distinct elements of personality (traits), not broad domains. Shows "strength of preference" on a scale, rather than categorizing people on one side or another.
  • Find our scale library here.
  • Candidates' responses are always compared to a norm group.
  • High levels of reliability and validity. Accredited by The British Psychological Society.

 

See below for further description on technical terms.

  • Rational model

    Born from desire to use personality assessments in the workplace. Assessments are specific to occupational settings. The rational model has the highest predictability of job performance.

  • Normative

    A type of scoring system which compares the performance of a candidate with a norm group of people who have taken the test before. The score is expressed as a percentile or standard score. Assessments on Psycruit are normative. 

  • Validity

    Does the test measure what it sets out to? Are the questionnaire items representative of the attribute being measured?

  • Reliability

    Does the test accurately measure what it sets out to? Would someone get the same results if they completed an assessment for a second time?
