Built in 1960, the high school has been twice renovated and added to: once in 1967 just after the jointure and again in 1995. It is the oldest operating regular school building in the district. The areas added in 1995 are most easily picked out in the aerial views below by the darker color roofs.
After the reorganization of 1982, the senior high became a 9th grade to 12th grade building and was renamed the Upper Merion Area High School.
