Our online application helps families manage both the admission as well as the enrollment process electronically. After an online application for admissions as well as the $100 application fee has been submitted, additional documents will be required to complete your application packet.


Required documents:

  • Academic transcripts and test scores
  • Teacher and principal recommendations
  • Placement testing
Placement Testing

Our placement test for 8th graders helps us to determine course placement in most of the core subjects; English, mathematics, and social studies. The test is required for all incoming freshmen and is offered throughout the year.  Sign up to reserve your spot!

Next testing times:
  • May 30 at 9 a.m.

After the admission process has been completed, you will receive a comprehensive Enrollment Package that will include cost details as well as information on uniforms and orientation. Our guidance department will share course recommendations prior to registration and final changes can be made at the event. Students admitted after March 7 will have individual registration appointments. 


Our admission process for transfer students has been simplified to ensure a smooth and seamless transition. We accept transfer students throughout the school year and the process can be completed in as little as a few days. 

Student Record Information

Althoff Catholic will submit a records request on your behalf to your current school but the information can also be mailed to Althoff Catholic High School, 5401 W. Main Street, Belleville, IL 62226 or sent by email to This information must include transcripts, test scores, and any other pertinent information including, but not limited to - attendance records, discipline records, physical, and immunization records.

Meeting With Principal

Once Althoff Catholic receives your student record information, a virtual or in-person meeting will be scheduled between the prospective transfer student, their family, Director of Admissions, and the Principal. An admission decision will be given during this meeting.


Our goal is to help our transfer students join our Crusader family as quickly as possible. After the admission process has been completed, you will immediately meet with our guidance department to discuss your graduation plan and your coursework for the school year. Our guidance department will prepare a transfer guide for you that outlines the graduation requirements and your progress.
