Opportunities for Students

Career Preparation

Students who take advantage of all that MacMurray offers are better prepared to enter their chosen field, and quickly begin a rewarding and accomplished professional career in criminal justice or homeland security.

MacMurray graduates have been hired by such agencies as the Springfield Police Department, the Illinois Department of Corrections, and the U.S. Postal Inspection Service.

Collaboration with Criminal Justice Agencies

MacMurray College's criminal justice staff utilizes extensive contacts developed from their years of professional service to augment the program, courses, and student opportunities. This allows the students to learn from hard-earned, unique, real-life experiences which they can then combine with their theoretical knowledge in the professional field upon graduation.


As a criminal justice degree student, you are required to attend at least one internship before you graduate, although you may perform as many as three. This opportunity allows you to work directly for the host agency, building contacts and gaining invaluable real-world, professional experience. The internship expands on the criminal justice curriculum, which assists students in developing the skills necessary to enter the job market. MacMurray College criminal justice students have completed internships with the Illinois State Police, Morgan County Sheriff's Office, Jacksonville Police Department, Springfield Police Department, and a host of other agencies throughout the nation. Other criminal justice internship placements have included prosecutor's offices, probation, parole, coroner's offices, and private sector placements.

Career Fairs

Criminal Justice and Homeland Security majors are encouraged to attend career fairs throughout the year. Attending career fairs is an excellent way for students to get to know and make themselves known to potential employers.

With MacMurray's close proximity to the state capital of Springfield, there are numerous opportunities to make such connections, and the Criminal Justice and Homeland Security programs often arrange for transportation to go in groups to such events. In addition, students are encouraged and helped to go further afield, to such events as the Law Enforcement and Justice Administration Career Fair every fall at Western Illinois University in Macomb, IL.


The curriculum is continually updated to keep pace with the latest criminal justice trends and developments. Additionally, instructors use professionals from the various fields of criminal justice to serve as guest lecturers. Our course offerings include a broad spectrum of criminal justice classes that includes forensics, cybercrimes, and critical incident management.


Beyond having the required academic qualifications, all faculty members are required to have been employed in the criminal justice arena and have a minimum of 10 years' service experience — they have either retired or are still serving in criminal justice agencies. Our current faculty consists of a state police district commander, a retired state police crime lab director, two correctional/parole officers, a criminal courts judge, and a federal prosecutor.

"The Illinois Emergency Agency (IEMA) is a state agency that helps communities recover after natural disasters, and the personnel are often police officers, firefighters, and EMTs. At IEMA we did a lot of revising policies the state uses during emergencies so I incorporated a lot of writing and grammar skills along with my knowledge of the National Incident Management System (NIMS) and the Incident Command System (ICS) that I learned in my major specific classes.

"This internship gave me lots of experience and insight into what happens when a disaster strikes Illinois such as a flood or tornado. I also discovered all the behind-the-scenes work that occurs when there is not a disaster. Along with experience and learning, interning at IEMA gave me the opportunity to network with professionals in my career field and to form relationships that could benefit me after I graduate."
