Validation of Psychomotor Skills Assessment Instrument For Electrical Installation And Maintenance Work In Technical Colleges In Lagos State

This study aims to validate a psychomotor skills assessment instrument to assess technical students' competence in electrical installation and maintenance work in Technical Colleges in Lagos State, Nigeria. The psychomotor skills assessment instrument was developed and validated through a three-stage process: the development of the survey instrument, pilot testing of the survey instrument, and validation of the psychomotor skills assessment instrument. The instrument was validated using a cross-sectional survey of 183 technical students from five Technical Colleges in the state. The psychomotor skills assessment instrument was validated using descriptive statistics, reliability analysis, and factor analysis. The results of the study showed that the psychomotor skills assessment instrument is valid and reliable, with a reliability index of 0.87 and a total variance explained of 65.20%. The findings of this study are important for the development of psychomotor skills assessment instruments that can be used to assess the competency of technical students in electrical installation and maintenance work.
