Between Fall 1976 and Spring 1978, a study was conducted at Bronx Community College (BCC) to determine: (1) the effect of probationary status on students' subsequent academic performance as measured by grade point average (GPA); (2) whether a response-to-probation phenomenon continued beyond the semester of probation; and (3) the effects of performance differences in various subject areas on the results. The study subjects were students in the College of Discovery program, who had enrolled in BCC in Fall 1975 and had completed 36 credits after Fall 1976. A probation group of 18 males and 27 females with a cumulative GPA between 1.75 and 1.94 was compared with a non-probation group of 30 males and 30 females with a cumulative GPA of exactly 2.00. The study revealed that probation students made higher cumulative and semester GPA's in Spring 1977 than non-probation students. A comparison of the Fall 1976, Spring and Fall 1977, and Spring 1978 GPA's of the groups revealed that the female probation group earned a higher mean GPA than the non-probation group for all three semesters after probation, while the male probation group earned a higher mean GPA only in Spring 1977. Very low grades in business courses were an important factor in women's assignment to probationary status; while men were generally on probation because of low grades in business, mathematics, and technology courses.
