Growth Model

Student Growth Percentiles (SGPs) complement the MCAS year-by-year test scores. They measure change in achievement over time rather than grade-level achievement results in any one year. Growth scores are available for schools, districts, and students taking the standard MCAS test in grades 4-8 and 10 in English language arts and mathematics.
