In 2011, the American Correctional Associations International Correctional Core Standards (ICCS) were created and include detailed standards relating to all aspects of adult correctional operations. The ICCS was first implemented in Mexico in 2012 and since that time have served as the basis for international accreditation, training and education conducted by ACA. In 2013, the ICCS was revised by ACA to improve clarity and functionality and to assist agencies in integrating these standards into their everyday operation. The ICCS is constantly reviewed to incorporate modern correctional practices that are useful to prisons and remand centers.
Over a dozen correctional facilities across Mexico are accredited by ACA, including both federal and state facilities. Other countries have begun the process of accreditation under ICCS which maintain exemplary, modern-day correctional practices.
