How to Apply
The application and admission process for CAST Teach High School occurs each school year, beginning in November, for enrollment in the following August. Admission is available only through this process.
Admission is open to incoming 9th, 10th and 11th grade students for the upcoming school year. CAST Teach is open to students in the greater San Antonio Area.
Students who apply will be admitted to the lottery pool. Once a lottery pool has been established from the applications that meet the initial criteria, the lottery will be conducted. Selections from the applicants are random. Students included in the lottery pool but not selected in the initial lottery will remain in the pool on a wait list, which will be used to fill additional spots as openings occur.
Applications open November 16, 2026 and close on January 22, 2027. All students will be notified of their acceptance or wait list status via email on February 1, 2027.

All students will be notified of their acceptance or wait list status via email during the week of February 02, 2026.
Students who are placed on the waitlist will be contacted beginning the week of February 15, 2027 via email about available seats.
