Many current instruments are designed to provide a bevy of scores to appeal to a variety of school psychologists. These scores are not all grounded in the attribute's theory or developed from sound measurement or psychometric theory. Thus,…

This study presents new models for item response functions (IRFs) in the framework of the D-scoring method (DSM) that is gaining attention in the field of educational and psychological measurement and largescale assessments. In a previous work on DSM, the IRFs of binary items were estimated using a logistic regression model (LRM). However, the LRM…
