This study investigated the effects of the college attended and the length of the educational program on ASCP Board of Registry Examination Scores. Registry scores were statistically analyzed for all graduates of Butterworth Hospital's (Grand Rapids, Michigan) Medical Technology program for the years 1970-80. Results indicated college differences in student academic preparation, as measured by the certification examination given by the ASCP Board of Registry. There were no statistical differences in average Registry examination scores for students who complete three versus four year educational programs. Other analyses considered sex differences in college grades and Registry exam performance, and the "grade inflation" phenomenon during the period of this study.
