The Mount Ida School for Girls, once a high school, became a
finishing school and was founded in 1899 by George Franklin Jewett, and was named after the hill on which it was located in
Newton Corner, Massachusetts. but was purchased by William Fitts Carlson in 1939 and relocated to its present location in the
Oak Hill section of Newton. The first
junior college level courses were offered at Mount Ida in the mid-1900s, and the school was officially re-branded as a junior college in 1961. It was subsequently granted the ability to award
associate degrees with the first being awarded in 1967. The school was later renamed as Mount Ida Junior College, and became a
co-educational institution in 1972 which was a logical step since many Vietnam veterans were attending college in the 1970s thanks to the
G.I. Bill. Several Boston-based institutions also merged with Mount Ida on the Newton campus: Chamberlayne Junior College (1988), New England Institute of Funeral Service Education (1989), and Coyne Electrical and Technical School.
Newbury College (which itself closed in 2019) announced that it would grant full transfer credit to Mount Ida students and would help them finish their degrees.
Keene State College and
Worcester State University also invited students to their campuses and committed to review applications for immediate acceptance and full credit transfer. Student records and transcripts are also maintained by UMass Amherst. In January 2026, UMass Amherst renamed the Mount Ida Campus to the Charles River Campus of UMass Amherst. ==Campus==
