Analyzing the Construct Validity of Work Readiness Instruments for Indonesian Law Faculty Students Using the Rasch Model

Abstract

Objective: The issue of undergraduate law students tends not to have clear work readiness, the data is obtained from several research results, the research findings have an indication of concern in interpreting the data which has an impact on inaccuracies in analyzing the data, the unclear construct of the instrument items studied, the measurements obtained depend on the characteristics of the test used, the item parameters depend on individual abilities, and measurement errors can only know for groups not individuals. Measuring instruments need to be tested for validity and reliability before being used on individuals to achieve valid and reliable goals. This study aims to test the validity and reliability of work readiness instruments based on the Work-Readiness Integrated Competence Model (WRICM) theory. Method: This research was conducted on 720 participants from several universities in Indonesia with a Cross Sectional Survey research design. The results of data collection were then analyzed through the Rasch model using the Winstep version 3.73 application. Results: The results showed a unidimensionality value of 36.1%, item reliability of 0.99. Of the 23 items created, there are 14 instrument items that have met the requirements of objective measurement. Conclusion: The Indonesian work readiness instrument obtained can be used to obtain data on work readiness needs as a foothold for determining the education strategy for law faculty students in Indonesia in terms of content, methods, and comprehensive evaluation.
