The main goal of the present research has been to predict the job performance of female high school teachers in Sirjan based on knowledge management components, and correlation research has been used in order to achieve this goal. The statistical population of the study consisted of all female high school teachers in Sirjan, 209 of whom were selected by means of random cluster sampling and then tested. Lawson’s knowledge management questionnaire (2003) and Paterson’s job performance questionnaire (1922) were used for data collection. Cronbach's alpha, calculated for the reliability of the questionnaires, was shown to be 0.95 for the knowledge management questionnaire and 0.82 for the job performance questionnaire. Based on the results obtained, the level of the components being applied by high school teachers was lower than average. Moreover, regarding the level of use of knowledge management and the level of job performance based on teachers' education and major, there was a significant difference among teachers, while based on age and experience, no significant difference between them was identified. Furthermore, the results indicated a positive, significant correlation between all knowledge management components and job performance. The results obtained from regression analysis pointed out teachers' job performances to be predictable based on knowledge management components. The component of dissemination of knowledge showed to have the highest share in predicting teachers' job performances, while the component of absorption of knowledge had the lowest.
