Avery Coonley School /

The Avery Coonley School (ACS), commonly called Avery Coonley, is an independent, coeducational day school serving academically gifted students in preschool through eighth grade (approximately ages 3 to 14), and is located in Downers Grove, Illinois, U.S. The school was founded in 1906 to promote the progressive educational theories developed by John Dewey and other turn-of-the-20th-century philosophers, and was a nationally recognized model for progressive education well into the 1940s. From 1943 to 1965, Avery Coonley was part of the National College of Education (now National-Louis University), serving as a living laboratory for teacher training and educational research. In the 1960s, ACS became a regional research center and a leadership hub for independent schools, and began to focus on the education of the gifted. The school has occupied several structures in its history, including a small cottage on the Coonley Estate in Riverside, Illinois, and another building designed by Frank Lloyd Wright. It moved to Downers Grove in 1916 and became the Avery Coonley School in 1929, with a new 10.45-acre (4.23 ha) campus designed in the Prairie and Arts and Crafts styles, landscaped by
