To analyze the relationship between teachers’ work values and job performance, 645 primary and secondary school teachers were tested by the Teachers’ Work Values Questionnaire (TWVQ) and Teachers’ Job Performance Scale (TJPS). Data were analyzed by SPSS17.0 program. The results indicated that teachers’ work values were significantly related to their job performance, but the correlation coefficient was lower; and altruism & devotion, security & stability and prestigious status were the predictors of task performance, job dedication and overall performance; and altruism & dedication, security & stability and interpersonal relationship dimensions were the predictors of interpersonal promotion. Teachers’ work values can predict their job performance to some extent.
