This study aimed to investigate the factors affecting teacher motivation and job performance/productivity at senior high schools in the Greater Accra region, Ghana. The study is quantitative in nature and survey approach was employed to gather data from 676 respondents out of sample size of 700. Descriptive statistical test as well as Exploratory Factor Analysis (EFA) and Confirmation Factor Analysis were used to analyze the data obtained from the respondents. In addition, tools such as mean, standard deviation, frequency and Ordinary Least Squares (OLS) were employed. The study found that motivations of teachers are low due to the lack of such variables as medical allowance, accommodation allowance, pension scheme, career advancement, recognition and low level of salary compare to their colleagues with the same qualifications in other government’s institutions and this is impacting negatively on their job performance. It was suggested by the teachers that major paradigm shift in Ghana education policies in connection to factors such as school governance, remuneration, safety and security, as well as assessments and evaluations needed to be revised for an improved performance.
