This book addresses the urgent need to strengthen the justice system in response to sexual crimes against children and adolescents, one of the most serious violations of human rights. It brings together more than a decade of experiences from the certificate program "The Rights of Children and Adolescents Who Are Victims of Sexual Crimes and the Judicial System," developed by the Amparo y Justicia Foundation and the Pontifical Catholic University of Chile. With contributions from 38 national and international experts, it examines three central dimensions: children's rights, the dynamics and complexities of these crimes, and the responses of the Chilean judicial system. Based on an interdisciplinary and evidence-based approach, it combines theory, critical reflection, and practical tools, making it an essential resource for professionals dedicated to child protection.
