Disciplinary records for 3rd through 8th grade students (n = 314) in an inner-city, public school were examined for one school year to assess students' variation in response to discipline. Rates of disciplinary referrals were compared for students who received no detentions or suspensions throughout the year (never group n = 117), students who received one or more detention or suspension in the fall but not in the spring (fall group n = 62), and students who received one or more detention or suspension in the fall and one or more detention or suspension in the spring (fall + spring group n = 75). Results indicated that during the fall, the fall group had nearly equivalent rates of referrals to the fall + spring group; however, the fall group exhibited significantly lower rates of referrals during winter and spring that were nearly equivalent to the never group, as would be expected for a punishment procedure. In contrast, the fall + spring group evidenced increases in referrals across the year, suggesting the possibility that detentions and suspensions were functioning as rewards for this group. The fall + spring group was rated by teachers and peers at mid-year as highly aggressive, lacking social skills, and high on hyperactivity, whereas the fall group and the never group were statistically equivalent on teacher and peer ratings. Implications for mental health programs for urban schools are discussed, especially the need for alternatives to detention and suspension for the subset of students who account for the majority of school discipline.
