Assessment/Accountability Massachusetts Comprehensive Assessment System
Growth Model

Massachusetts has developed a statistically valid method of measuring growth in student, group, school, and district performance over time. The growth model complements the MCAS year-by-year test scores, since it reports change over time rather than grade-level performance results in any one year. Growth scores at the group, school and district levels are available here: http://profiles.doe.mass.edu/state_report/mcas.aspx. District administrators also have access to growth data in the Education Data Warehouse by way of the Security Portal.
