How to Apply

Application Window

The application window to attend in the 2025-26 school year is November 8, 2024 - January 31, 2025.  Please apply at the link below.

During the application window, use our online application portal to complete and submit an application.

Students interested in attending must submit an application during the application window. The application window for all secondary schools of choice closes January 31. Some schools may reopen their application following Spring Break for enrollment through a waitlist if space is available. We strongly encourage students to apply during the application window. 

If there are more applicants than seats available, selection of students will be by lottery drawing of applicants, followed by a student and parent conference with administration, school staff and students.

Please carefully read the information in this section to determine if our school is a good fit for you. Your name will be placed in the lottery only if you commit to all requirements and submit any requested documents.
