Analisis Aitem Subtes Figural UGRT pada Seleksi Masuk Pendidikan Profesi Psikologi Universitas Sumatera Utara

Abstract

The selection process for the Professional Psychology Education Program requires valid and reliable assessment tools to evaluate the cognitive potential of prospective students. The UGRT (USU General Reasoning Test) serves as one such instrument, with its figural subtest designed to measure visual-spatial reasoning abilities. This study aims to analyze the item quality of the figural subtest of UGRT, focusing on reliability, discrimination index, and difficulty level. The study employed a descriptive quantitative method using secondary data from 67 respondents. Reliability was assessed using Cronbach's Alpha, item discrimination was measured through item-total correlation, and difficulty level was analyzed based on the proportion of correct answers. The results showed that the figural subtest's reliability, indicated by Cronbach's Alpha, was 0.488, suggesting a low level of reliability. Most items demonstrated low to negative discrimination indices, and the majority were categorized as difficult based on their difficulty indices. These findings highlight the need to revise the test items to enhance the validity and reliability of UGRT as a selection tool.
