The usefulness of item response theory for the construction and evaluation of noncognitive tests in personnel selection and assessment

In this article we discuss the use of IRT for the development and application of noncognitive measures in personnel selection and career development. We introduce the basic principles of IRT and we discuss the usefulness of IRT to evaluate the quality of items and tests to assess the measurement precision of a candidate’s trait level, and to investigate item and test bias. Furthermore, we describe several applications of IRT, including computerized adaptive testing and the development of item banks in an automated testing system. Finally, a list of software programs is provided to stimulate the use of IRT models.
