Bacon Academy's doors opened to the children of Colchester on the first of November 1803 and from that point forward, prepared many young men and women for the life that lay ahead.

In its early days, Bacon Academy had a reputation of preparing its students for accomplishment at universities and colleges around the country.

In 1886, the branch structure was abandoned for the current four-year system; and by 1890, the first modern commencement was held, with each graduated student receiving a diploma.

[5] The school bell would toll at five-thirty in the morning during the first and third term and at seven in the winter for those in branches one and two, during which two scholars would be chosen each day to practice public speaking in front of instructors and other students.

In or out of classes, each was to behave properly and dress neatly—or risk punishment by means of "reproof, correction, admonition, or expulsion."

[5] After the centennial celebration, the national reputation of the school declined and the Academy drew its students chiefly from Colchester and surrounding towns.

A major building spurt in the 1980s again impelled construction of a new high school, less than a mile east; the doors opened at the present site in 1993.
