Apply to IMSA!
We look forward to working with you throughout your application process! The application deadline for the 2024-2025 School Year is March 1, 2024.
IMSA is accepting a small group of non-Illinois students for paid enrollment. The application process is the same for Illinois and non-Illinois students. You can apply online in the admission portal by following the steps below.
You can find more information about our Admissions Process in our official Admissions Policy.
If you have any questions, please contact the Admissions Office.
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 (March 1st). If their school does not offer these courses, they will need to find supplementary courses through an accredited institution to meet this requirement.

The IMSA application has no application fee. The application consists of the following:
- Demographic and School Information

- List of STEM Activities and Achievements
- Parent Statement
- Three Teacher Evaluations
- 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.
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.
Students have the option of taking the SAT or ACT. All scores must be official and sent to Admission directly from the testing company.
- Students can register for the SAT through CollegeBoard.org.
- Students should take the standard SAT, Math, and Evidenced-Based Reading & Writing sections without essay.
- When registering, please use IMSA’s SAT school code #3027 to ensure that we receive a copy of your test results.
- Students interested in taking the ACT can register through ACT.org.
- Students should take the standard ACT without writing.

Applicants are required to submit 3 Teacher Evaluation Forms from the following subjects:

Starting December 1st, students can send the Counselor Form to the current counselor (or school administrator who oversees transcript requests). To request the Counselor Form visit SchoolRecs by using the same login credentials of your application portal. In SchoolRecs, you will see a list of evaluation forms, including the counselor form. Once selected, you can enter the counselor's email, so they can receive the evaluation form and submit transcripts. 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.
Before March, 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 email@example.com or by phone 630.907.5028.
Students should log into their student account (PowerSchool) 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 is done manually, so we appreciate your patience.
