 District reference groups are defined as "districts whose students' families are similar in education, income, occupation and need, and that have roughly similar enrollment".The other seven school districts in the group are Ansonia, Danbury, Derby, East Hartford, Meriden, Norwich, Norwalk, and West Haven.In early 2007, school officials said they worry that a child might be seriously injured in an accident involving the school's many large glass windows, some of which are floor-to-ceiling and not shatter-resistant.
