The Reintegration Process synthesizes the institutional purposes of the ARN. Its scope is delimited by the PRSE and is structured based on the legal mandate of the institution and its strategic framework.

The Colombian Agency for Reintegration (ACR – Agencia Colombiana para la Reintegración – for its acronym in Spanish), today the Agency for Reincorporation and Normalization (ARN) was created by Decree 4138 of 2011, which assigns the objective of "(…) manage, implement, coordinate and evaluate, in an articulated manner with the competent bodies, plans, programs and projects of the Reintegration Policy, with the aim of ensuring peace, security and coexistence". Thus, some functions and a structure are established for the implementation of the Reintegration Policy.

The strategic framework of the ARN is the result of a reflective work in front of the challenges, opportunities and learning related to the implementation of the PRSE from when it was created, in 2006, the former High Counseling for Reintegration. This work provided the guidelines until the year 2020.
