The Present research aim is to study the effect of training strategy of cognitive – behavioral on test anxiety reduction among female high school students. The present study is a semi-experimental study. The statistical population of 70 female students of Tehran high school was selected by the multi stage randomized method and assigned into 2 groups as experimental and control (each group 35 people). Instrument of data collection in this study was Ahvaz test anxiety scale (ATAS). The questionnaire was completed in two stages before, and a week after the intervention by both groups, and then the data analyzed. Results showed that the average of test anxiety has significantly decreased in the experimental group (p<0/05). Training cognitive-behavioral strategies can be effective on the reduction of test anxiety of students. With regard to this paper we suggest that using training cognitive-behavioral strategies can be useful for test anxiety reduction of students and increase their performance in exams.
