Sex education at schools has been a topic of constant controversial discussion for many decades. A number of studies focus on quality and extent of sex education in Austria, suggesting approaches and improvements of all kinds. Living in a globalized world, it seems natural to ask how sex education is carried out in other European countries. The reason why England has been chosen for this study is easily explained. The United Kingdom is the country with the highest teenage pregnancy rate in Western Europe in 2010. This trend has been observed for many years and could not be reversed so far. It goes without saying that sex education and teenage pregnancy are topically related. This book deals with sex education in England and focuses on students aged 11 to 16. A co-educational secondary school in West London has been selected as case study for a common English comprehensive school.
