The social educational program presented in this article, GENER@T, has been designed and developed as a response to the needs found in the diagnostic multimethod study descriptive which was carried out between 2008 and 2011. 701 adolescents from 5 State secondary schools in different parts of Spain took part in the study. The aim of the diagnosis was to detect social educational needs about gender based violence in adolescents of between 12 and 14. The program presented is innovative in the prevention of gender based violence in two ways: firstly it aims to anticipate the first dating relationships, aiming the intervention at the pre-adolescent stage and secondly the 24 sessions which make up the program means it can be applied transversally as an "optative subject" in a formal educational field or as a workshop in a non- formal educational field. The program "GENER@-T" consists of three parts: the first part is a presentation of its characteristics, the second part is a theoretic guide which records a summary of the content needed to carry out the sessions and the third part is a description of the activities, their objectives, content, techniques and resources needed.
