ATDSCS accepts students from throughout the greater Albuquerque area, including its surrounding vicinities, in grades 9-12. Open enrollment is advertised throughout the year, allowing students to enroll while vacancies exist, or to go into a fair and open lottery when ATDSCS reaches its target total population of 200 students. Students will be issued a number, and once the 201 student enrolls, the lottery takes effect. Applications are available online or can be mailed. For further information on enrollment, you may call (505) 503-2465 or you may drop by the school office.
