Background & Objectives: In order to improve the quality of teaching attention to the students academic progress is important In the present study the internal consistency of students scores has been used as an index for the evaluation of the validity of course exams Methods: All scores of Pharmacy students graduated in 2007 and 2008 were collected from the of Kerman University of Medical Sciences We computed the Pearson correlation coefficient (r) between course scores and grade point average (GPA) In addition coefficients between the mean score in subgroups of courses with GPA were computed Results : In most courses the correlation coefficient between the course score and GPA was in the range of 04 to 06 The lowest correlation coefficients belonged to sport course (004) and thesis (033) while the highest were for theoretical biochemistry (078) and practical chemistry (076) The correlation coefficient of male students scores was 049 and that of female students was 040 that shows significant difference (p < 001) In whole the scores of basic courses showed higher correlation compared to general and special courses The correlations in theoretical and practical courses were equal Conclusion: It seems that this convenient method for investigating the internal consistency of course scores can be used as an index for validity of corse scores Significant difference in correlation coefficients among different courses requires special attention to some courses for investigating the probable testing errors even though in most courses the coefficients were in the acceptable range

Background & Objective : Assessing students grades in their courses and in national comprehensive exams may help us in the assessment of educational status of different departments indirectly In this study the internal consistency of medical students scores in Kerman University of Medical Sciences was assessed Methods : In a historical cohort study students grades and other information for entrance years between 1995 and 2003 were extracted from the central admission office and 10 indicators for educational achievement were defined for each student Having used Cronbachs alpha and linear regression we checked the internal consistency of scores Also we used factorial analysis and related graphs (Dendrogram) to evaluate the consistency between factors of students educational achievement Results : Females were more successful in all series of students except for national comprehensive exams Although internal consistency in males scores was more than females males scores in specific courses of basic sciences were more related to the scores of their basic sciences comprehensive exams In addition internal consistency in males scores was more than females especially in clinical courses Higher age at entering university could cause a decrease in educational success Students grades in various courses had slight consistency with national comprehensive exams Moreover the internal consistency of scores during clerkship and internship were significantly lower than the other phases Conclusion : Lower consistency of scores in clinical courses may imply lower validity of these scores Unlike higher educational success in females it seems that stability in males scores was greater in most indicators
