The present study  attemted to investigate the correlates of graduate enrollment behavior of  the Thai government officials. There were three major research  objectives : 1) to compare the graduate students with their counterparts on attitudes towards continued education and some important personality traits. 2) to examine the 
differences in psychological traits of the students  and nonstudents who were in the same or different situation, in relation to the favorableness for continued education 3) to search for important predictors and to compare their degree of predictability of graduate enrollment behavior in various types of respondents. 
           The sample in this study consisted of 120 graduate students of Srinakharinwirot 
University Prasarnmitr and 120 government officials which totaled 240 respondents. The two groups of respondents were matched on the following criteria; 1) same sex 2) holding Bachelor' s degree 3) length of the periods after graduation differed no more than 3 years. 4) holding similar work position. 
           The questionaires consisted of five parts; 1) Graduate enrollment behavior and 
other related information 2) Three assessments of  personality traits which Type A personality, Fear of failure and Fear of success 3) Four measures of State Characteristics including Social support, Work stress, Attitudes towards continued  education and Subjective norms (in Fishbein' s Theory). These measures composed of 14-25  items accompanied 
with six-unit scale.  4) An assessment of family responsibility and a work security report and 5) The assessment 
of the bio-social characteristics of the respondents. There were  the total of 14  variables in this study. 
            In this study, the statistical analyses of the data were carried out by computer. The Discriminant  Analysis with stepwise  and Three-way Analysis of  Variance were performed on the data of the whole sample as well as from the subsamples categoried by the levels of each of the 6 bio-social characteristics of the respondents. There were the total of 12 subsamples. 
          There were 5 major research findings as follows: 
          First, it was found that the 13 variables could account for 87 % of the enrollment 
behavior. It could be said that graduate students were younger, single, and better off but were more stressful at work, but reporting higher work security, showing higher positive attitudes towards continued education and were more fearful of success than their counterparts. 
           Secondly, the nonstudents were mostly older but according to the results from the Analysis of Variance, it could be said that, these older respondents if they possessed more favorable attitudes towards continued  education and become a stronger A typed, they showed stronger probability to continue their education. 
           Thirdly, the respondents who percieved lower work security would not continue their education. But another part of the research result showed that, these people, if they percieved less family responsibility on their shoulder and have favorable attitudes, they were more likely  to continue their education. 
             Forthly, it was found that, the respondents with lower socioeconomic status would not continue their education. But the poorer but younger respondents were more among the graduate students than their counterparts. 
             Finally, less favorable attitude holders with strong encouragement from the people around them (high in subjective norm)  were more among the graduate students than their counterparts. 
              Therefore, it could be recommended from the results in this study that, the important factors which can induce the Thai government officials to continue their higher education are favorable attitudes towards this education, strong social encouragement and high work security.
