The present study examines the effect of child neglect, alone and in combination with abuse, on academic achievement and school disciplinary problems for elementary, junior high, and senior high students. The sample included 324 neglected children and adolescents, and a matched nonmaltreated sample of 420 children and adolescents. All subjects were in grades K through 12 in a small city in New York state. The results revealed that neglected children did perform more poorly than their nonmaltreated counterparts, having lower grades, more suspensions, more disciplinary referrals, and more grade repetitions, even when controlling for gender of child and SES. Neglect alone and neglect in combination with physical or sexual abuse was related to lower grades and more suspensions. The combination of abuse and neglect had a particularly strong effect on the number of disciplinary referrals and grade repetitions. Abused/neglected students in junior high had the highest number of grade repetitions. The number of disciplinary referrals continued to increase through senior high for both neglected and abused/neglected students. Interestingly, the academic performance of all subjects dropped during junior high. Neglect and neglect in combination with abuse appeared to exacerbate a decline in academic performance that occurs as children enter junior high school.
