Featured tool

How does your Connecticut school district compare with districts like it?

District Comparison Tools compares every Connecticut public school district with its peers – districts that serve similar students – on two questions at once: effectiveness, measured by the District Accountability Index (DAI), and efficiency, measured by Achievement Return-on-Investment (A-ROI).

  • Build a comparison group around your own district.
  • See which districts deliver the strongest results for what they spend.
  • See what the analysis means for your district.
