Results achieved in this study showed poor motivation for teachers, a situation which had a domino effect on academic and job performance, hence the study is expected to contribute on awareness to the government and other educational stakeholders about the importance of teachers‟ motivation towards job performance.

Based on these findings, the study concludes that, in order to obtain quality education, the issue of teachers‟ motivation is inevitable, and should be a central agendum that needs to be prioritized by the government as one of its pre conditions to make it realize its aspiration of having an industrialized country as part of middle income countries.
