Three district elementary schools (Ring Street in Howland, Curtis School in West Enfield, and the Burlington School in Burlington) closed and all students moved to the new school.

Each grade has three classes, with the exception of third grade that has two (classes)."

Budget Problems
On August 24, 2011, new district superintendent Michael Wright, unveiled a public letter indicating that the school had a $1.2 million deficit. This led to severe austerity, including that all new purchases must be made through him, and layoffs of ed. techs and teachers.
