The study evaluates the efficacy of an intensive, reading intervention, a dropout prevention intervention, and an intensive, reading intervention plus dropout prevention on high school students' reading achievement and rates of dropout/school engagement. This paper focuses on the reading intervention and on reading outcomes. Data on the drop out intervention continues for the next 2 years. The research questions include: (1) What is the efficacy of an intensive reading intervention, with adolescent struggling readers compared with a well-documented, school-implemented comparison group on post-test reading performance? and (2) What is the moderating effect, if any, of primary language status and special education status?
