Avery Coonley School, Downers Grove

The Avery Coonley School, commonly called Avery Coonley, is an independent, coeducational day school serving academically gifted students in preschool through eighth grade, and is located in Downers Grove, DuPage County, Illinois. 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, 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. ()
