Parkside Intermediate School was opened in 1954, followed by additional elementary schools: Rollingwood, Crestmoor, John Muir, and Carl Sandburg. A second intermediate school, Engvall, was built in Crestmoor Canyon, only to be closed, along with North Brae and Sandburg, when enrollment fell. These were all part of the San Bruno Park School District. Students in northwestern San Bruno were included in the Laguna Salada district. The private school, Highlands Christian School, is also located in San Bruno. Founded in 1966, Highlands Christian School is an interdenominational school, and offers preschool through college preparatory school instruction.
