Dear Families,

Welcome to Cleveland Arts & Social Sciences Academy (CASSA). Cleveland Arts and Social Sciences Academy was founded in 2015 on the simple convictions that a first-rate education is the birthright of every individual, and that every child should be challenged to reach his or her full potential. Our mission is to surpass the global standards of academic excellence by investing in partnerships with our students, community and home environments, in order to encourage the development of creativity and self-direction. We ensure that all students receive the focus and attention required to achieve academic excellence by engaging each student through their unique talents.

Our teachers and staff meet students where they are and move them to higher levels of performance. By focusing on the entire child and using a holistic approach, each student’s passion for learning is ignited. CASSA has truly embraced the motto “Failure is not an option.”

We encourage all parents/guardians to maintain regular communication with their child’s teachers and be actively involved in the school community. Checking the school calendar, website, and our Facebook page for events and activities will help keep you informed.

If you should have any questions, please feel free to contact the office by calling 216-229-3000. We are looking forward to meeting your child and helping foster a love of learning.
