This sexuality education reference guide aims to systematically and coherently bring together information on sexuality education policies and programmes across Europe. The guide is divided into three broad sections. The first section gives an overview of the situation in Europe, and analyses the similarities and differences that various countries have experienced in delivering sexuality education, the factors hindering and enhancing provision, and evidence for the effectiveness of comprehensive sexuality education. This section is followed by three tables which describe the situation in Europe in more quantitative terms, and that can be used to give at a glance data and comparisons between countries. The final section contains individual country reports that describe in more detail the situation with regards to sexuality education in each of the 26 countries covered.
