This report was prompted by the pressing concerns over the high failure rates of Latino students on the Massachusetts Comprehensive Assessment System (MCAS) exam. While 27% of White students failed the English portion of the MCAS test and 38% failed the Mathematics portion in 2000, the corresponding rates for Latino students were 66% and 79% respectively (Massachusetts Department of Education, 2000a). There is a great urgency to understand why Latino students score substantially behind students from other racial/ethnic groups. This urgency stems from the reality that students currently enrolled in the 10th grade will be required to pass this exam in order to receive a high school diploma in 2003
