The present research investigated if an item response theory ( IRT )‐scored forced‐choice personality questionnaire has the same normative data structures as a similar version that uses a 5‐point L ikert scale instead. The study was conducted using a sample of 349 training delegates who completed both an IRT ‐scored forced‐choice and a normative single‐stimulus version of the questionnaire. Results largely supported the scaling properties, measurement precision, and equivalence of the data structures of the two scoring methods.
