Though a substantial number of researches for finding the factors responsible for job satisfaction and its impact on employee performance in organisations can be found, an inclusive identification of the dynamics of job satisfaction that arises due to the academic compatibility of the employees is yet to be undertaken in the context of Bangladesh. It is argued that a comprehensive study to explore the effects of the compatibility of the educational background of the employees on their job satisfaction is relevant and necessary. It is also argued that this effect may not be similar in different types of organisations, so, the inter service comparison among them is also important. This study has included different types of organisations. Data was collected from 288 employees having a minimum number of 30 from each type of organisation by using stratified random sampling technique. This study has used Structural Equation Modeling (SEM) to address the simultaneous behaviours of the selected variables. It is seen that educational compatibility has significant influence on the job satisfaction as well as job performances of the employees. But the effect and its significance are not same in the organisations of different nature. Based on the responses from the faculties of the universities, it is found that educational compatibility has significant effect on job satisfaction of the employees which is positive. In case of private bank employees, it is found that the educational background has no significant effect on their job satisfaction. It is also seen that those who had aim and plan to join in this profession are more satisfied.  The findings of this paper give some guidelines to the policy makers to understand the current scenario and the expectation of the employees working in different organisations about their job satisfaction in reference to academic compatibility. Findings of the study and the experiences from the interviews with employees recommend that the government should devise an effective long run plan from the tertiary level of education by calculating the needs of subject specific employment for the organisations of the country which may improve the job satisfaction of the employees and in turn their performance and productivity which in the bigger picture helps the growth of national economy.
