Massachusetts policymakers have expressed concern about the consistently lower scores of Hispanic students, compared to other subgroups, on the Massachusetts Comprehensive Assessment System (MCAS). This summary describes a larger report that examines Hispanic high school students' performance on the MCAS tests in English language arts and mathematics over 2002/03-2005/06. It compares the scores of grade 10 Hispanic and non-Hispanic students and uses multilevel regressions to examine associations between the Hispanic students' scores and student- and school-level characteristics.
