An analysis of 10453 enrollments in freshman chemistry was made. Of these 3648 had the same instructor in recitation and laboratory, and 6805 had different instructors; 5.4% of those having the same instructor failed; 8.3% of those having different instructors failed. 3.1 % of those having the same instructor received a grade of 95% or above; only 1.9% of those having different instructors received a grade of 95% or above. Taking 80% as the dividing point, of those having the same instructor 41.6% were below and 58.4% above. Of those having different instructors 48.9% were below 80% and 51.1 % above. The test and final examination grades are not so uniform as these final grades but in general the better grades are received by those who have the same instructor in recitation and laboratory.
