Riverdale High School's principal is Mr. Waldo Weatherbee. Some other teachers include Ms. Grundy, Mr. Flutesnoot, Ms. Haggly, and Coach Kleats and Coach Clayton. The school's chef is Ms. Beazly. The high school's main rival is Central High School.
The high school runs a school newspaper called The Blue and Gold.
The school was established under controversial circumstances. The first controversy arose because the school was created in the early 1990s to avoid having the district's century-old grade school affected by new statewide laws promoting consolidation. In 2001, controversy continued, as the district asked voters to allow a permanent site be built for the school at a location outside of the district's boundaries. This was at a time when the high school had only 100 students, 30 of whom were actually district residents.
