Abstract Creative-thinking judgments in large-scale assessments often combine multiple evaluative criteria into one score, which can blur interpretation and measurement precision. This article focuses on PISA creative-thinking judgments and introduces a generalized item response tree approach to separate appropriateness and originality into distinct latent components.
