Abstract
- A procedure to detect differential item functioning (DIF) is introduced that is suitable for tests with a cutoff score. DIF is assessed on a limited closed interval of thetas in which a cutoff score falls. How this approach affects the identification of DIF items is demonstrated with real data sets. (SLD)
