In accordance with the Roman Catholic Church of Phoenix, St. Thomas Aquinas Catholic School admits Catholic and non-Catholic students of any race, color, national origin or gender to all the rights, privileges, programs and activities made available to any of its students.

New families must complete an Application for Admission and submit it along with the most recent report card and standardized test scores. The Application for Admission will be reviewed and once openings are established, a testing date (if applicable) is scheduled. Other details regarding the application process are noted on the Application for Admission.

Typically open enrollment for our school takes place each March; families are encouraged to start the application process in January. Upon acceptance into our school, the enrollment process will be initiated. We believe in providing new families with as much information as possible as they join our school community, including partnering new families with a mentor family.
