Computerized adaptive testing (CAT1) refers to the procedures underlying a test/assessment/whatevs that is generated “on the fly” by a computer, using a person’s previous answers to determine what question the person will see next. My amazing, trade-mark infringing, artwork notwithstanding, CAT is not magic – it is, in fact, SCIENCE! A reader-friendly conceptual overview of CAT was recently published here: https://www.ispor.org/ValueOutcomesSpotlight (paywall warning!). I’ll wait while you go read that… Finished? Great! OK – so now we know that … Read More
