St. Michael School was built in 1940 during the period when the immigrant children were being more fully exposed to the influences of the secular education opportunities that were part of the American system. The ethnic parishes were encouraged to create local schools that were more aligned to those in their countries of origin, where there was less distinction between church and state.

The school on New Haven's Green Street, a neo Art Deco-fronted building, was adjacent to the original parish center, St. Michael Hall. With space for eight classrooms, it was designed to accommodate children right through their entrance to high school. The school was a source of pride for the parish, and considered by some residents to be a worthy investment in their child’s future.
