We have a few programs that require additional materials or screening so make sure you check.  Here are our freshman admission requirements.

Southern Illinois University admits freshman applicants who have graduated from high school. We do make exceptions for students participating in our High School Concurrent Enrollment program and for those who have earned the G.E.D.

You should apply well in advance of the term you want to attend. To get your application on the priority review list, all application materials are due by December 1.

Freshman Admission Requirements

To be considered, you must submit:

  • A completed application for admission.
  • A $40 non-refundable application fee. Fees may be waived for students who meet certain income levels. See your high school guidance counselor for details.
  • Current, official transcripts from each high school and college you’ve attended.
  • High School Transcripts
    Ask your high school to send your official transcripts to us using one of the following methods:
    • Email PDF transcript directly from a high school official’s email to admprocess@siu.edu
    • Send through an electronic transcript service
    • Mail official transcripts to Undergraduate Admissions
  • College Transcripts
    If you have completed college coursework, ask your college(s) to send your official transcripts to us using one of the following methods:
    • Email PDF transcript directly from a school official’s email to transferservices@siu.edu
    • Send through an electronic transcript service
    • Mail official transcripts to Articulation and Evaluation

Applicants will be eligible for automatic admission if they are on track to complete the high school course pattern requirements and meet one of the following criteria:

  • A cumulative high school GPA of 2.75/4.0.
  • A ranking in the top 10% of their graduating class.
  • A test score equivalent to a 23 ACT or 1130 SAT.

Undergraduate students who do not meet one of the three criteria above will be reviewed for admission under a holistic review process. Certain academic programs may continue to have additional admission requirements.

Homeschool students must submit official transcripts. Partial transcripts for admission purposes can be submitted via email by the homeschool organization or teaching parent. Final homeschool transcripts must be submitted by the homeschool organization or teaching parent in a sealed envelope through the mail. 

Additional Requirements

An additional step or screening process is required for certain programs. Requirements for direct entry into some programs exceed university admission requirements. Please be sure to read the Special Conditions section.

High School Course Pattern Requirements

High School Concurrent Enrollment

SIU's High School Concurrent Enrollment program permits high school sophomores, juniors, and seniors to enroll at SIU for regular college credit. The application procedure is similar to that required for SIU freshmen. Submit a completed undergraduate admission application and a copy of your official high school transcript. Applicants must have achieved a B grade point average in high school and have their principal fill out the Request for Concurrent Enrollment of High School Students form. Test scores are not required. The University courses to be taken in this program should be in subject areas in which a high school does not offer courses or in subject areas in which the student has completed all of the courses the high school can offer.
