What do these numbers mean?

DESE accountability percentiles (1–99) compare schools administering similar assessments, using up to two years of indicators. These are not test scores out of 100 or GreatSchools 1–10 ratings. Progress toward targets is a separate state measure. Consider programs, support services and your child’s needs as well.

School names link to available school or district websites.
