About Classen SAS at Northeast

  • History

    Classen High School, constructed immediately following the close of World War I, is the oldest high school building in Oklahoma City. Classen opened as a junior high school in 1919. The land was part of an area being developed by the early Oklahoma City real estate developer, Anton H. Classen. A total of 6.33 acres was purchased by the Oklahoma City Public Schools Board of Education for $55,100. The building was constructed at a cost of $420,500 by the Holmboe Construction Company. The two story brick building was enlarged in 1921, 1923, 1925, 1934 and 1957. The school was converted to a high school in 1925. 

    In 2019, the vision of Classen SAS expanded to two campuses, which saw the high school moving to 3100 North Kelley and 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. 


    Classen School of Advanced Studies High School at Northeast (CSASNE) is the premier school of its kind in the state of Oklahoma. CSAS offers eligible qualified students of Oklahoma City Public Schools in grades 9° through 12° a rare and dynamic educational opportunity.

    It is our vision to develop healthy, creative, and innovative citizens, and ensure successful transition for graduates by providing quality instructional programs that prepare our students for college, university or conservatory/fine arts institutions.


    Students at Classen SAS High School at Northeast select one of two rigurous programs offered att he school:

    • About the International Baccalaureate Program

    Classen SAS students who choose this program will prepare for a future high school path that follows a two-year curriculum focused on the development of high quality, academically prepared global citizens. The general objectives of the IB Program are to provide students with a balanced education, to facilitate geographical and cultural mobility, and to promote international understanding through shared academic experiences. 

    The IB curriculum includes eight subject groups: Language acquisition, Language and literature, Individuals and societies, Sciences, Mathematics, Arts, Physical and health education, and Design.

    Students who choose this path will gain skills that will teach them how to think independently and drive their own learning, take part in programs of education that can lead them to some of the highest ranking universities around the world, become more culturally aware through the development of a second language, and be able to engage with people in an increasingly globalized, rapidly changing world.

    • About the Visual and Performing Arts Program 

    Classen SAS students who choose this program will prepare for a future high school path with rigorous conservatory-style training in the arts while offering a college preparatory academic program. The curriculum provides students the opportunity to pursue their goals and passion for the arts in a pre-professional learning environment.

    Students must audition for one of the eight art forms which they wish to study at Classen: Dance (Ballet and Modern Dance), Piano, Vocal Music, Concert Band, Concert Strings, Guitar, Drama/Theatre, and Visual Art. Students will perform for the school and the public through art exhibitions, drama productions, concerts and dance programs. 

    The program is demanding but the conservatory-style Visual and Performing Arts Program will provide students with ample opportunities for growth in valuable skills, such as high level problem solving and decision making, increasing motor skills and body connectivity, and finding connection and understanding to the world around us. Additionally, the program will steep students in the literature and culture of the arts, resulting in uniquely accomplished and educated students, well prepared for the professional and university worlds.
