Abstract
Education is a consumption good that provides both financial and pecuniary benefits, contributing to a nation's growth and development. The study examined the relationship between investment in graduate teachers' education programmes and job satisfaction. A descriptive correlational survey design was used in the study. The population comprised 92,469 teachers from Southwest Nigeria. The target population consisted of 35,616 individuals, from which 432 were randomly selected. Three validated instruments were used for data collection. The reliability was established using Cronbach's alpha with coefficients of 0.78, 0.82 and 0.80. Means, frequencies, and charts were used to answer the research questions, and the Pearson Product-Moment Correlation Coefficient (r) was used to test the hypothesis at a .05 alpha level. The study found that job satisfaction is not directly and significantly related to investment in graduate teachers' education. The findings imply that investment in teacher education programmes may not directly correlate with teachers' satisfaction after training. Thus, the teaching profession should be attractive to teachers-in-training to encourage them to stay in the job after completing their teacher training programme. It was recommended that teachers’ service conditions improve job satisfaction and make the teaching profession more attractive.
