What it is
Criminal justice is the study of the systems that maintain law and order — policing, courts, and corrections — plus crime, law, and public safety. It prepares graduates for careers across law enforcement, federal agencies, corrections, courts, and private security.
Important: a criminal-justice degree does not by itself make you a sworn officer — that requires a state POST academy and background check. And most forensic labs prefer a science degree over a generalist CJ degree. The CJ degree is, however, the standard credential for federal agencies and a boost for promotion.
