Ethnicity, drug user status and academic performance
1Freeport Public Schools, New York, USA.
Abstract:
The impact of drug use and race on school performance was investigated. Data were collected retrospectively from a sample of 100 students in Grades 9 through 12, using a questionnaire devised by the authors. Most recent grades in English, mathematics, social studies, and science, and percentile scores on the mathematics portion of a recent Metropolitan Achievement Test, constituted achievement. Sufficient data were obtained for 38 students (11 black, 18 white, and 9 Latino). Results included significant main effects for both race (p < .05) and user status (p < .05). An interaction of race and user status was suggested. While black users and nonusers did not differ across academic areas, large differences for the two other ethnic groups emerged.
