JOINT PREDICTION OF MANPOWER DEVELOPMENT DIMENSIONS ON TEACHERS’ JOB PERFORMANCE IN PUBLIC SECONDARY SCHOOLS IN ANAMBRA STATE, NIGERIA

Abstract

Teachers’ job performance is central to the effective attainment of educational goals, yet concerns persist regarding the quality and effectiveness of teachers’ performance in public secondary schools in Nigeria. This study examined the predictive relationship between manpower development and teachers’ job performance in public secondary schools in Anambra State, with particular attention to in-service training, mentorship, research collaboration and conference participation. A correlational research design was adopted. The population comprised 5,949 teachers in 268 public secondary schools in Anambra State, from which a sample of 1,187 teachers was selected using proportionate simple random sampling across the six education zones. Data were collected using the Manpower Development Questionnaire (MDQ), Delegation of Authority Questionnaire (DAQ), and Teachers’ Job Performance Questionnaire (TJPQ). The instruments were validated by three experts, while reliability coefficients of 0.81, 0.79 and 0.85 were obtained respectively. Multiple regression analysis was used to analyse the data at the 0.05 significance level. The reported regression model produced a moderate multiple correlation of \(R=.48\) and explained 23% of the variance in teachers’ job performance (\(R^2=.23\)). The overall regression model was statistically significant, \ (F (4,970) =72.56, p<.05\). In-service training made the strongest relative contribution (\(\beta=.37\)), followed by conference participation (\(\beta=.27\)), research collaboration (\(\beta=.14\)), and mentorship (\(\beta=.08\)); all four predictors made statistically significant positive contributions. The findings indicate that systematic professional development constitutes an important organisational factor associated with teachers’ job performance. The study recommends sustained investment in relevant in-service training, professional conferences, collaborative research and structured mentorship. However, the supplied regression output contains only the four manpower-development variables and therefore does not provide statistical evidence for the combined eight-variable model of manpower development and authority delegation.
