What is the MCAS?
The Massachusetts Comprehensive Assessment System (MCAS) is a set of statewide standardized tests. Students in grades 3–8 and 10 take MCAS tests in English language arts and mathematics; students in grades 5, 8, and one high school grade (usually grade 9 or 10) take a science MCAS test. Students in grade 8 take a civics MCAS test.

Why does Massachusetts give MCAS tests?
Statewide testing gives families an objective measure of their child's and school's progress and is one way for taxpayers to see the results of their investment in schools. State test scores are just one piece of a student's academic picture, but they provide important information. In addition, federal and state laws require statewide testing.
