In 1985 the school celebrated its golden anniversary of being an accredited four-year high school. At this time over half of the student body came from outside of the Washington city limits, truly making it a “regional” high school. The growing number of students and more rigorous academic requirements made way for another expansion program which began in 1998. This included thirteen new classrooms, two remodeled science labs, remodelling and enlargement of the theater, chapel, and cafeteria, a weight room, an elevator, additional offices, and restrooms. In 2001 the High school was accredited as a college preparatory high school by the North Central Accrediting Association.
