In a competitive, cost-effective situation where managers need continuous improvement, attending training courses is the best option. Training, as a suitable tool for acquiring knowledge, makes it possible for managers to apply scientific methods in the management of tasks. The current research is done to evaluate the service quality of the education center of Mellat Bank in providing the educational service to the managers of the Mellat Bank Branches in Gilan province based on the SERVQUAL model. This research is of survey-descriptive and the statistical population consists of 60 of managers of Mellat Bank branches in Gilan Province that were under expertise training in 2018. Since the population size of the study is not much, therefore, the whole research population was studied. Data collection was conducted using the SERVQUAL questionnaire in 2019. Cronbach’s alpha was used to determine the reliability that is obtained by 91%. To determine the validity of the questionnaire, experts’ opinions were used. Data analysis was conducted using a two-sample t-test to understand the difference between each one of the aspects of the model. The results showed that there is no significant difference between the expectations of the managers of the Mellat Bank Branches of Gilan Province and the services received from the education center of this Bank, indicating the relative satisfaction with the quality of services provided in this center.
