UJI VALIDITAS DAN RELIABILITAS INSTRUMEN KOMPETENSI KERJA MAHASISWA

Abstract

This study examines the validity and reliability of a student work competency instrument
designed to measure underlying individual characteristics causally related to effective and
superior performance. The instrument is developed based on the Spencer and Spencer
competency model, which includes five dimensions: motive, trait, self-concept, knowledge,
and skill. Measurement uses behavioral indicators distinguishing superior and threshold
performance as indicators of students’ readiness to meet workplace demands. This study
employed a descriptive quantitative approach involving 209 undergraduate students from
higher education institutions as participants in an instrument try-out. Item validity was
assessed using corrected item–total correlation, while reliability was examined using
Cronbach’s Alpha. Results indicated that 48 of 60 tested items were valid. Reliability
analysis produced a Cronbach’s Alpha coefficient of 0.945, indicating very high internal
consistency. Overall, the findings demonstrate that the instrument is reliable and suitable
for assessing student work competencies and supporting students’ readiness for career
transition.
