We look forward to working with you throughout your application process! The application deadline for the 2025-2026 School Year is February 14, 2025. You can apply online in the admission portal by following the steps below.
IMSA is accepting a small group of non-Illinois students for paid enrollment. All non-Illinois students must follow the Out-of-State student application timeline.
You can find more information about our Admissions Process in our official Admissions Policy.
If you have any questions, please contact the Admissions Office.
Step 1: Check Your Eligibility
Check that you meet all Eligibility Requirements.
8th-grade applicants must also be enrolled in at least Algebra 1 and a high school-level science course and must have at least 50% of the course completed by the application deadline (February 14, 2025). If their school does not offer these courses, they will need to find supplementary courses through an accredited institution to meet this requirement. Here is a list of popular program choices among our applicants.
Step 2: Application
To begin the application process, access the admission application online by clicking here.
The IMSA application has no application fee. The application consists of the following:
- Demographic and School Information

- Parent Statement
- Three Teacher Evaluations from Current Teachers
- School Counselor Form
- Last 2.5 years of Official Grade Reports

The “Optional Statement” can be utilized to provide additional clarity on any part of the application or include information that you feel would be important for you or your child’s success at IMSA.
Step 3: Student Essays
Applicants are required to submit two essays each 300-500 words answering the prompts provided in the application. Students will need to upload their essays to the application directly.
Step 4: Testing
Students have the option of taking the SAT or ACT. All scores must be official and sent to Admission directly from the testing company. All test scores must be submitted before the application deadline (February 14). Any scores received after the deadline will not be accepted. It is important to note that the admissions department will not accept the SAT / ACT test scores that fall after the application deadline.

Step 5: Teacher Evaluation Forms

Step 6: Counselor Form and Transcripts
Starting December 2, students can send the Counselor Form to the current counselor (or school administrator who oversees transcript requests). It's important to note that counselors will need to upload official transcripts from the last 2.5 years and instructions on how to send official transcripts are included on the evaluation form. As a reminder, IMSA cannot accept transcripts from students or their families, all transcripts must come from the school itself. If you have sent the request to your counselor and they have not received it, visit our Application Troubleshooting FAQ’s page for assistance.
Step 7: Follow Up with the Admissions Office
Before February, connect with the Office of Admissions to ensure all your application materials have been received. You can contact the Office of Admissions by email at admissions@imsa.edu or by phone 630.907.5028.
Students should log into their student account to view their Admission Tracker checklist. You will see a list of materials needed. Materials received will have a green check mark by them. The admission staff is working to update all checklists, which are done manually, so we appreciate your patience.
Step 8: Visit IMSA (Optional)
Learn more about IMSA’s exceptional learning experiences, residential program, and admissions process. All admission events are posted on our Visit IMSA page. Please be sure to register for our events as spaces do fill up quickly. Event registrations are opened the month prior to the event and close two days before the event date. Once the application has closed, students will not have an opportunity to visit campus until decisions have been made and students sign up for orientation.
