Mount Pleasant was one of the first schools built following the passing of the free school law of 1829. On September 22, 1830, Joseph Orr sold a lot to the School Committee of School District #2. The original Mount Pleasant schoolhouse still stands today, located on an acre of land which is now part of Bellevue State Park. When William DuPont Jr. remodeled Woolton Hall, now called the Bellevue Mansion, he also changed the exterior of the Mount Pleasant schoolhouse from stone to its present Colonial Revival style. In 1865, the school moved to a new location on Philadelphia Pike, just across the street from the Mount Pleasant Methodist Church, and then again in 1932 to a much larger facility on Duncan Road. In 1958, Mount Pleasant High School opened at its present location on Washington Street Extension. In 1978, the Mount Pleasant Special School District and other school districts in Delaware dissolved due to desegregation, and Mount Pleasant High School became a part of the New Castle County School District. Quinton Sterling became the first African-American principal of the high school. In 1981, the larger district split into four separate school districts, and Frank J. Furgele became the superintendent of the newly formed Brandywine School District. The school celebrated their 175th anniversary in a series of events during homecoming weekend, October 14 and 15, 2005, including the inaugural Mount Pleasant Hall of Fame.
