The Psychometric Lab
Good assessments are measured, not claimed. The Lab analyses every test on Match.hr as data comes in, and helps organisations and test developers research their own instruments.

Validation that keeps going
Classic validation happens once and ages. On Match.hr, item statistics, norms and fairness checks are recalculated on an anonymised dataset as administrations grow, so the evidence stays current.
Every test gets a psychometric label
One page that shows what a test is for and how much evidence stands behind it.
Reliability
Internal consistency (α, ω), test–retest and item–total correlations.
Validity
Factor structure, convergent and criterion validity against real outcomes.
Norming
Norm groups per country, language and role, updated as samples grow.
Fairness
Differential item functioning and measurement invariance across groups, where lawful.
Adaptive testing
Item response theory so strong candidates answer fewer, harder questions.
