A study was conducted at Catonsville Community College to investigate the relationship between grade received and attendance during the fall 1971 semester. No attempt was made to establish a cause-effect relationship. Analyses were based upon a sample of individual grades and percentage of attendance as reported by faculty. Grades analyzed totaled 9,322 (5,525 freshman and 3,797 sophomore grades), 56% of the total number of grades. Data were analyzed for these subgroups: freshmen, sophomores, new students, returning students, transfer students, full-time, part-time, numbers of credits completed, and composite profiles. "Beyond toleration" levels were established for percentage of absences beyond which the level of absence group's mean grade was below 2.0. The data clearly establish the existence of a strong relationship between attendance and grade awarded for the population as a whole and within each group. The degree of the relationship is highest for students completing 0-10 credits. Mean QPA's for each of the other groups rise as the degree of the relationship lessens. Thirty-eight percent of all F grades in the sample occurred within the absence level that could be tolerated. Grade distribution and academic action data do not support a hypothesis that the present attendance policy has had an adverse effect upon grades or withdrawals. (KM)
