Sherwood High School is a secondary school in Sandy Spring in unincorporated Montgomery County, Maryland. Sherwood's program of interest is the international studies program, and is also known for its music and athletic programs. Sherwood draws students from Farquhar and Rosa Parks Middle Schools.Sherwood serves the towns of Olney, Ashton, and Brookeville.HistorySherwood Academy was built on a piece of land donated in 1883, that was once part of Sherwood Farm – named because the abundance of trees was reminiscent of Robin Hood's Sherwood Forest. In 1906, Sherwood became the third public high school in Montgomery County, after Richard Montgomery High School and Gaithersburg High School. The original school building was replaced in 1950, and the one thousand seat Ertzman theatre was added in 1974. The school was renovated in 1989-1991, during which students were temporarily moved to the Northwood High School building in Silver Spring. During the summer of 2007, a new wing was added to the school, creating new class rooms for science and English.
