Child Sexual Abuse (CSA) is an uncomfortable reality whose numbers are rising every year. The purpose of this book is to make CSA visible from several perspectives. It explores its definition, the consequences for victims, the factors that favor it and the erroneous beliefs that surround it. In addition, schools become ideal places to observe warning signs and provide preventive education, guiding both students and parents on how to detect and deal with risk situations. To this end, we analyze preventive programs implemented in different educational centers in order to find and adapt one that is appropriate to the school context and the needs of the students. In this way, we can act as a bridge between the child and the family, where educators can play a fundamental role in protection.
