Students who want to learn more about criminal behavior may want to study criminology. Related classes might include human rights, social justice, policy development, human behavior, prison systems, criminalistics, biocriminology, and psychology.

Many students earn associate degrees during their first few years of higher education. Since they usually require about two years of study, these degrees can act either as job qualifications or as precursors to more advanced degrees.

Part-time learning allows one to obtain a degree or qualification even if one cannot attend school on a full-time basis. One can learn at one's own pace, gradually accumulating credits that count towards a final qualification.
