How long will it take?

There are many two-year diploma programs offered at career colleges and vocational or trade schools that prepare students for front-line and entry-level jobs in specific fields of criminal justice. Those wishing to enter policing, private investigation, bylaw enforcement, customs and immigration and many other careers often take this route.

Some schools, generally community colleges, offer two-year associate's degrees. Others offer four-year Bachelor of Arts degrees in criminal justice or criminology.
