(ECPAT International) The Terminology Guidelines for the protection of children from sexual exploitation and sexual abuse (“Luxembourg Guidelines”) are a tool guiding child protection professionals all over the world in their choice of words. Adopted by large consensus by the Interagency Working Group (IWG), composed of major international child protection agencies, they contribute to a more coherent, but also a more adequate and child-centered terminology in the work against sexual exploitation and sexual abuse. To respond to the needs expressed by child protection professionals, and make sure that the Luxembourg Guidelines can be a useful tool for professionals at all levels, ECPAT International developed this Handbook to facilitate the translation and adaptation of the Luxembourg Guidelines into other languages.
