摘要：Assessment of competency including the knowledge, skills, and abilities of an employee is vital to provide good information for an employer to enhance employees’ future performances as well as maintaining organization performances. To measure the current level of employee competencies, tools such as an instrument for competency measurement that is valid and reliable should be used. To provide the validity and reliability evidence, instead of using the classical test theory (CTT), another measurement model that can be utilized to conduct a more precise measurement is the Rasch Measurement Model (RMM). This paper describes the application of the Rasch Measurement Model toward a study on competency measurement instrument development and validation. A discussion of several RMM diagnoses such as Person and Item Separation Index, Item Polarity, Fit Statistics, Item Dimensionality, Standardized Residual Correlation, and Differential Item Functioning (DIF) can be used to guide social science researchers in developing an instrument to measure employee competencies.
