The answer is mixed. Generally in the lower grades Killingly schools perform better on the Connecticut Mastery Tests, however at the high school level, Middletown students generally perform better on the Connecticut Academic Performance test. That said though, neither school district performs above the state averages. Class sizes appear to be slightly lower in Killingly. You can compare schools by checking out the Connecticut Department of Education's Strategic School Profiles on their website. Hope this helps. Jay
