An Exploratory Study of the Applicability of Item Response Theory Models to Construct Teacher Made Achievement Test

Abstract

This study aimed at investigating the applicability of item response theory (IRT) models to construct a teacher made achievement test. A test consisting of 23-multiple choice items measuring 23 intended goals was constructed and applied to (284) pupils. Item responses were analyzed according to IRT. Results of the study revealed non-applicability of the IRT to construct tests consisting of few numbers of items.
