Welcome to the SAGE companion site for Introduction to CorrectionsFourth Edition!

Introduction to Corrections provides students with a comprehensive foundation of corrections that is practitioner-driven and grounded in modern research and theoretical origins. Experienced correctional practitioner, scholar, and author Robert D. Hanser shows students how the corrections system works, from classification, security, and treatment, to demonstrating how and why correctional practices are implemented. The Fourth Edition includes a special emphasis on the role of technology in each chapter; new topics on medical care in jail, female drug offenders, and controversies around the death penalty; and the impact of the COVID-19 pandemic on correctional practices. Data and examples drawn from federal government documents, along with exercises that reinforce concepts in the text, further aid student learning.

This site features an array of free resources you can access anytime, anywhere.
