Training Assessment as Determinant of Senior Secondary School Principals Job Performance in Lagos State

In recent years, it appears that the job performance of principals in public senior secondary schools in Lagos State seems to be deteriorating. Despite the efforts of educational stakeholders, the situation appeared to remain unchanged. Previous studies had identified various factors contributing to principals’ poor job performance in other states, but limited research had specifically addressed this issue within the context of public senior secondary schools in Lagos State. To address this gap, the studyinvestigated training assessment as a determinant of principals’ job performance in Lagos State. A descriptive research design, using a survey approach, guided the study. The population consisted of all 323 principals in public senior secondary schools in Lagos State. A total enumeration sampling technique was employed, and a self-developed questionnaire for principals, with a reliability coefficient of ? = 0.821, was used. The findings indicated that the job performance level of principals in Lagos State was high (x?=3.19), the level of training assessment was also high (x?=3.07), and training assessment had a significant influence on principals' job performance (? = 0.403, t = 7.674, p < 0.05). The study concluded that effective training assessment was crucial for enhancing principals’ leadership functions and improving overall school performance. Based on these findings, the study recommended strengthening post-training evaluations, institutionalising comprehensive professional development programs, and ensuring consistent training quality across all schools.
