Our ISA magnet school program is available to high school students across San Antonio, regardless of school district boundaries, however based on their physical address at the time of application, students are sorted into two pools - in-district and out-of-district. With limited space, each grade level can only accommodate 125 students. For an application to be considered complete, applicants must respond to three short answer questions. This streamlined process allows ISA to thoroughly assess applicants to ensure an incoming class of engaged, motivated students.
