Study Period:
One district was selected in each of four Southwest Region states (Arkansas, Louisiana, New Mexico, and Texas) to evaluate the effectiveness of the Fuchs et al. (2005) intervention in multiple populations. The study includes 74 schools (37 intervention, 37 control) from four urban districts. Of the nearly 3,000 students screened, some 920 were identified as at risk (560 intervention, 360 control) in 308 classrooms (173 intervention, 135 control). In October and November 2008 all students in grade 1 who were receiving core math instruction in English and whose parents provided signed consent were administered a math screening test. Beginning in December 2008 and lasting until April–May 2009, intervention school students identified as at risk received the small group tutoring intervention.
