Classen Middle School of Advanced Studies (CSASMS) is the premier school of its kind in the state of Oklahoma. CSASMS offers eligible qualified students of Oklahoma City Public Schools in grades five through eighth grade a rare and dynamic educational opportunity. Two complementary and challenging plans of study are offered: the world recognized International Baccalaureate Program and the nationally recognized Visual and Performing Arts Program.

The Mid-High School opened in the August of 1994. In 2019 the vision of Classen SAS expanded to two campuses, the High School moving to 3100 North Kelley, with the Middle School remaining at the 1901 North Ellison address. With two campuses united under one vision and offering expanded opportunities to more students than ever before, it's easy to see why Oklahoma City has truly become #CometCity.
