During the early 1950s, Barrington's population began to grow as a result of the increasing availability of the automobile and the baby boom. Barrington High School was the first of many public schools constructed during this period to accommodate the now larger populace.

Barrington High School has been noted for academic success; Niche ranks Barrington as the best public high school in Rhode Island. In its 2014 list of "America's Top High Schools", Newsweek ranked Barrington High School as No. 200 out of an analysis of 500 schools across the United States. Beginning in 2017, the school began implementing a "de-leveling" program which removed advanced courses and ultimately all honors programs. Thereafter, the school's academic rating dropped precipitously in the U.S. News & World Report, to #308 in 2022. As a result of parents' pushback against this, the school reversed course and said honors programs will be reinstated in the 2022-2023 school year.
