Mandates biennial comparisons of private contractor performance versus state-operated facilities across ten criteria including security, inmate management, programs, safety, administration, food service, personnel, health services, and discipline.

Requires the director to conduct cost comparisons of executed privatization contracts once every five years and provide results to the joint legislative budget committee.
