Richwoods High School opened in 1957 and originally served the Richwoods Township community in Peoria, Illinois.

During the 1960s, administrative changes brought the school into Peoria Public Schools District 150.

Over the following decades, Richwoods developed its academic programs, student organizations, athletics and arts activities.

Its International Baccalaureate programme received authorization on July 3, 2001, providing an internationally recognized college-preparatory curriculum.

The school also offers Advanced Placement courses and other academic pathways.

Richwoods describes its educational mission as supporting academic achievement, personal growth, and social responsibility within a diverse community of learners.

Its campus remains a part of Peoria's educational landscape.
