At a glance
Connecticut rates schools with the Next Generation Accountability System — an index score (a percentage of possible points across a dozen indicators) — published on EdSight, rather than a letter grade or stars.
How this state rates schools
The index earns points across 12 indicators: achievement, growth, achievement gaps, English-learner progress, chronic absenteeism, preparation for college/career (like coursework and exams), graduation, postsecondary entrance, physical fitness, and arts access. The result is a single accountability index (a percentage). Read the indicator detail alongside the index.
What gets measured
Under the federal ESSA law, every state rates schools using several indicators. They typically include:
- Academic achievementHow students score on state tests (proficiency in reading/ELA and math)
- Academic growth / progressHow much students improve year to year — not just where they land
- Graduation rateFor high schools (the 4-year cohort rate)
- English-learner progressHow English learners are progressing toward proficiency
- School quality / student successAn extra indicator — often attendance/chronic absenteeism, college/career readiness, or similar
Finding & reading the report card
Look up any school on EdSight (edsight.ct.gov). Review the indicator breakdown (especially growth and absenteeism) and the trend alongside the index.
How families should use ratings
A rating is a helpful starting point, not a verdict. Use it wisely:
- Read it in contextA school’s score reflects its students’ circumstances too, not only its quality
- Look at growth, not just scoresGrowth shows how much a school moves students — often more telling than raw proficiency
- Check the trendIs the school improving over time?
- Look past the summaryDig into the underlying data (subgroups, attendance, readiness)
- Then visitData raises questions; a visit answers them (see our guide on evaluating a school)
Tips for families
- Start on the official portalLook up your specific school, not just district averages
- Weigh growth heavilyHow much a school moves students matters as much as test scores
- Mind the contextRatings partly reflect student demographics and circumstances
- Compare a few schoolsRatings are most useful for comparison, in context
- Pair data with a visitNumbers plus a tour give the real picture
