The purpose of this study was to manage total quality management (TQM) to increase the standard of management policy and contribute to achieve the standards for health promotion hospitals (HPHs). This was a quasi-experimental intervention study. A total of 35 managers participated in this study were selected in the census. Based on the TQM components, educational items were provided as lectures, posters and pamphlets. The TQM questionnaire and HPHs checklist used to collect data in three different periods: before the interventions, immediately after the interventions and 3 months after the interventions (follow-up). The data analysis was done by means of SPSS software (version 23). The results showed that the average difference of the components of the qualitative groups (p < 0.001), education (p = 0.004), evaluation and feedback (p < 0.001), customer-orientation (p < 0.001), suggestion system (p = 0.024), leadership commitment (p < 0.001) was significant over the three periods. Excluding the employment status before the educational intervention (p = 0.002), there was no significant relationship between the demographic characteristics and mean score of TQM (p > 0.05). Based on the findings of this study, the educational interventions had a positive effect on quality management and management policy. Therefore, educational interventions should be accompanied by changes in the culture and management policies of the hospital to meet HPH standards.
