Introduction: Today evaluations of psychological indicators have a non new found role on the process of psychological evolution. One of these important indicators is memory. Purpose: the current research has the purpose of indicating the right norm from the Wechsler\'s school memory sub-test software on girl and boy students studying at pre-university level in the city of Tehran in the 87-88 school year. Procedure: this research by nature is a descriptive study and of a survey and normalization type which has applicative aspects. For this purpose a sample of 370 people (N=370) consisting of 170 men and 200 women from between students at the pre-university level of the province of Tehran were selected by using multistage cluster sampling. To evaluate constructive validity and factorial structure of this test, factorial test was used and to compare the averages of the two groups (girl and boy) an independence t test was used. Also to calculate the final test coefficient from the internal consistency method calculation of Cronbach\'s alpha coefficient has been used and from the retest method calculation of Pearson\'s correlation coefficient between the scores obtained from two times performing the test has been used. Findings: the results obtained from the research showed between all of the 8 dimensions of Wechsler\'s memory in the space of two performance in the frame of retest a positive meaningful relation exists (p<0/0001). Also the highest rate of correlation belonged to the reverse visual memory component (r=0/83) and the lowest index of correlation belonged to the auditory memory span component (r=0/40). Validation by using the retest method showed that between all the dimensions in the frame of two computer performance and a monthly retest a meaningful correlation exists among which the sum of the auditory memory (r=0/82) had the highest correlation and the sum of the visual memory (r=0/53) showed the lowest correlation. By using the independent t test comparison of the average score of boys and girls in the multiple memory dimensions showed that between the two groups considering the dimensions no meaningful difference exists (p>0/05). Conclusion: the current research findings can be considered in the application areas and in the area of psychometrics it can open the path.
