A criminologist wishes to evaluate a new parolee release program that provides job skills. A person convicted of a felony is often referred to parole when first released from prison. While on parole, a parolee must meet with an parole agent at regular and frequent intervals, must undergo random drug tests and searches of the residence, and can be returned to prison for parole violations at the request of a parole agent.
