By using the administrated questionnaire, data were collected and analyzed by SPSS. The results of the study were as follows: the average score of organizational commitment was about 59/8 and there was a significant relationship between index of employees' organizational commitment and their education; it was an adverse relationship with a weak intensity. This relationship has been observed only in employees' organizational commitment. Also, there has been a significant relationship between the average index of employees' organizational commitment and their employment status. According to the results, the average of contractual employees' commitment was more than other groups [official and etc].
