Research
One study reviewed by the WWC investigated the effects of ALAS . The study (Larson & Rumberger, 1995) was a randomized controlled trial that met WWC evidence standards.4
Larson and Rumberger (1995) included 94 high-risk students who entered junior high school in Los Angeles as seventh graders in 1990, with 46 students randomly assigned to ALAS and 48 assigned to the control group. The study measured outcomes at the end of ninth grade (the last year of the intervention) and the end of 11th grade (two years after the intervention ended).5
4 An additional analysis in Gándara et al. (1998) focused on outcomes in grades 9–12 for a subsample of the initially randomly assigned sample (81 of 94 students). The analysis meets WWC standards with reservations because different rules were used to exclude students from the treatment group and the control group. Here, these results are treated as a subgroup analysis, which does not bear on the intervention’s rating of effectiveness.
5 The outcomes for progressing in school were collected only for students who continued to be enrolled in the district, which depends on whether students dropped out. Therefore, the analysis of these outcomes meets WWC standards with reservations.
