History
The Bay State Conference was established in 1958 and included ten charter member schools. In the fall of 1990, the conference expanded to 12 schools with the additions of Brookline and Newton North, and split into two divisions. The divisions were originally based on enrollment and named after Mr. Fran Carey and Mr. Fred Herget; they are known as the Carey Division and the Herget Division of the Bay State Conference (BSC). In 1991, Framingham North and Framingham South merged into one school, creating an opening in the BSC, filled when Weymouth was admitted to the BSC in 1997. Beginning in the Fall of 2018, divisional placement was altered on the basis of geography. Divisional alignments are reviewed in October of odd years.1
