Aristoi Classical Academy is a K-12 open-enrollment public charter school based in Katy, Texas. The school opened in 1996 as West Houston Charter School, with an emphasis on fine arts. In 2006, the student population declined with many unfilled seats. After careful deliberation, the school's board of directors voted to transition to a classical school model, an educational option previously available only in area private schools. The school currently has three campuses, two of which serve a portion of the Katy Independent School District area, and the remaining serves the Cypress Fairbanks Independent School District area.
