Argentina’s Comprehensive Sexuality Education (ESI) law is marking its 20th anniversary, prompting a review of its impact and future direction. The law has demonstrably advanced the prevention and detection of abuse cases nationwide, a significant achievement over the past two decades. However, it remains a focal point of intense political and ideological controversy within the country. Since its enactment in 2006, the law has undergone changes and interpretations, leading to ongoing discussions about its implementation and scope. Critics raise questions regarding certain aspects of the curriculum and its alignment with diverse values. The current government is now outlining plans for the law’s future, navigating a complex landscape of support and opposition. The review highlights both the successes and challenges of incorporating comprehensive sexuality education into the Argentine education system.
