A follow-up study was conducted at William Rainey Harper College (WRHC) of students who had completed several courses in the Criminal Justice Program to determine why students left the criminal justice field, examine Criminal Justice students' enrollment and course-taking patterns, and to analyze withdrawal and failure rates in the course, Introduction to Criminal Justice (CRJ-101). The study involved the analysis of enrollment and grade data for all 1,481 students enrolled in CRJ-101 between 1981 to 1985, transcript analysis for the 865 students who successfully completed the course, a telephone survey of 223 students (with 162 responding) who had completed five or more criminal justice courses, and a telephone survey of 123 students (with 82 responding) who had left the field while at WRHC. Study findings included the following: (1) 23% of the students enrolled in CRJ-101 between 1981 and 1985 withdrew (compared to an institutional withdrawal rate of 14%), and 18.5% failed the course; (2) among those who successfully completed CRJ-101, 31% went on to complete five or more criminal justice courses, while 17% changed fields; (3) in comparison to the WRHC student population as a whole, criminal justice students were more likely to be reverse transfers, were younger, and had lower high school ranks; and (4) among those who had taken five or more criminal justice courses, 59% were employed or enrolled in a field closely related to criminal justice. Detailed study findings and the interview schedules are appended. (EJV)
