Reliability estimate for university Scores in a sample of courses in Princess Norah Bint Abdulrahman University in light of some of the variables. The study aimed to estimate the relaiability of the university Scores in the sample of the courses at the University of Princess Noura Abdul Rahman for girl. The sample of the study consisted of scores in (96) of the courses presented in the first semester of the academic year 2014/2015. The Courses were selected randomly cluster which comprises in the three sections in the Colleges of Education, Science, Computer and information, and business and management. To estimate the relaiability the researcher applied Raju equation. The results of the analysis indicated the low reliability coefficients in general were the average for the consistency estimates (0.67). The results indicated that (47.92%) of the courses acceptable reliability which are increases reliability coefficient for her (0.70). The scores in College of Education tends to be less reliability in the average compared to other colleges. The results of the chi - square test of independence were existence of a relationship between the degree of reliability of the Courses and the level of Courses, and there is no relationship between the degree of reliability of the Courses and the college to which they belong. The study recommended the need to reduce the negative effects of the problem of apparent disparity in the practices of faculty members in the grades awarded to students at various colleges in the university departments, which reflected negatively on the reliability.
Key words: Reliability, Internal Consistency ,Raju equation, Scores courses, Grade inflation.
