The target of this study is to measure the satisfaction of graduate and Ph.D. students with some of the educational and technical aspects of universities and their services to them by using the theory of TAM3. Conversely, the Technology Acceptance Model 3 (TAM3) technicality was employed with the (Xl STAT) program to explain the adoption process to measure user behavior. The total number of students is 261 male and female students in different universities in Turkey. (TAM3) was adopted in the present study to construct study tools and to evaluate user behavior. Seventeen factors were tested which are (“Perceived Usefulness (PU), Perceived Ease Of Use (PEOU), Self-Efficacy (SE), Perceptions of External Control (PEC), Playfulness (PLAY), Perceived Enjoyment (ENJ), Objective Usability (OU), Anxiety (ANX), Subjective Norm (SN), Voluntariness (VOL), Image (IMG), Job Relevance (REL), Output Quality (OUT), Result Demonstrability (RES), Behavioral Intention (BI), and Actual Use (AU)”) [20]. The results showed that the TAM3 model was fit for this kind of problem. Moreover, the results of the statistical analysis show that the magnitude or volume relationships of variables by the model were significant and precise except for the subjective norm from Result demonstrability that was not supported, and users are satisfied with the performance of the technology tools that are used in their universities.
