This paper presents an empirical investigation to study the relationship between employee performance and TQM. The proposed study of this paper designs two questionnaires for TQM and performance measurement and distributes them among some employees who worked for one of Iranian banks in city of Semnan, Iran. The result of Kolmogorov–Smirnov test confirms that all data are normally distributed and the study uses Pearson correlation to investigate the relationship between various components of the survey. The result of the implementation of Pearson correlation ratio indicates that there was a positive and meaningful relationship between employee performance and TQM components (r=4.6223, P-value=0.000). In addition, there are some positive and meaningful relationships between TQM components and employee performance. The highest correlation belongs to relationship between employee performance and feedback (r=4.6223, P-value=0.000) followed by training and development (r = 0.441, P-value = 0.000) and communication (r = 4.2861, P-value = 0.000).
