Yes. In general, students can earn a bachelor's degree (with any major) in any state. In fact, all students really need to be a police officer in most states is 60 accredited college credits along with completing a law enforcement skills program. Generally speaking, students have to complete the skills portion of the law enforcement training in the state in which they would like to be employed as a police officer. Even students who earn a bachelor's degree in criminal justice from UW-Eau Claire who want to be police officers in Wisconsin will still need to complete the Wisconsin law enforcement skills training (at a technical college like CVTC)
Likewise, if a student earned a bachelor's degree from an accredited university in Minnesota, he or she would still be required to complete the POST program in Minnesota (the law enforcement skills training). If a student earned a criminal justice degree from UW-Eau Claire and wanted to be a police officer in MN, the institution where he or she would enroll to complete the POST curriculum would evaluate the courses he completed here to determine if any satisfied any of the required courses. Some do, but it all depends on what school the student attended. We have MANY students who complete our degree and ultimately move to another state to work in law enforcement (Minnesota being the most common).
Many states do have reciprocity agreements with other states once an officer has reached a specified number of years of experience. For example, if a student was to complete a bachelor's degree here at UW-Eau Claire, complete the skills training for Wisconsin, and work in law enforcement for 3 years, he or she would be eligible to be a police officer in Minnesota after completing the "Reciprocity License Examination" offered by the POST board in MN. There are some restrictions on this, and more information can be found here.
