This study aims to develop a score equating application for computer-based school exams using parallel test kits that have 25% anchor items, the items are arranged according HOTS (High Order Thinking Skill) category and use scientific approach characteristics of physics lessons. So questions made stimulus, options, logical systematic. The research method used is Research Development (R&D), ...

BACKGROUND Item response theory (IRT) has been increasingly applied to patient-reported outcome (PRO) measures. The purpose of this study is to apply IRT to examine item properties (discrimination and severity of depressive symptoms), measurement precision and score comparability across five depression measures, which is the first study of its kind in the Chinese context.
