One specific area of focus in the criminal justice field is public administration. Jobs such as city/county manager, systems analyst and industrial relations name only a few of the opportunities available to those who seek a degree program in this area. Even better now, is that if you are seeking to get a promotion or make a career change in the field, you don't have to quit your day job. Several online criminal justice programs offer degrees in public administration. Two popular ones are Norwich University and Walden University.
