The IIP is an intervention program designed to promote lawful behavior in offenders by providing a structured, specialized program that develops responsibility, self-esteem and positive self-concept, while also addressing the underlying issues that often lead to criminal behavior. The program promotes public safety through risk management in the selection of participants and reduces the demand for prison bedspace by shortening the time to serve for successful participants. The typical IIP inmate is a 22-year-old black male with an 11th-grade education and a history of substance abuse. He has been convicted of a property or drug offense and is serving a 4.1-year sentence. Of the first 1,388 graduates of the IIP, 25 percent were returned to prison for committing a new crime within 3 years after release. The percentage in a comparison group of parolees who did not participate in the IIP was 35 percent. During fiscal year 1996, the cost savings for the IIP netted $7,011,046, saving over 833,139 days of incarceration for the 1,593 graduates. The total cost savings since the program's inception were an estimated $20,482,373. Tables, figures,
