Grading standards in departments and school divisions at Stanford University were analyzed, along with grading trends, and the classroom performance of students with different majors. From 1975-1976 to 1981-1982, the proportion of A grades decreased, while B and C grades increased. In 1976, D grades were reinstituted. Considerable variation in grading standards of the various school divisions was found. Grading was highest in the humanities, with nearly half of all grades reported as A's, while it was lowest in the School of Engineering. Even more variation in grading standards was found for individual departments. Generally, the level of grades varied inversely with the degree of technical content of the subject area, with the national sciences and engineering having the lowest grade distributions and the humanities and social sciences the highest. Grades were inversely related to class size in all of the school divisions. Humanities classes had greater enrollments in smaller classes, while the natural sciences had greater enrollments in large classes. Natural science majors did better in nearly all fields and were more likely than other students to earn awards at graduation. Information is also provided on the relationship of grades and Scholastic Aptitude Test scores. (SW)
