Admission into the criminology and criminal justice graduate program requires a grade point average of 2.70 or higher from the last 60 hours of undergraduate courses for applicants with a bachelor's degree, or from the last 45 hours of undergraduate courses for applicants completing their bachelor's degree.

Graduate school applicants who do not hold an undergraduate degree in criminology and criminal justice must have a minimum 12 hours of coursework in sociology, psychology, political science or another social science field.

Applicants must submit a graduate school application, three letters of recommendation, transcripts, and a personal statement highlighting academic achievements and goals for pursuing graduate education.
If you are an international student, you will need to take the TOEFL English proficiency test and have that submitted with your application (the minimum requirements for English proficiency by the SIU Graduate school are: 550 on the paper-based TOEFL, 213 on the computer-based TOEFL, 80 on the internet-based TOEFL, or, 6.5 on the IELTS).
