Based on observation of sex education programmes and in-depth interviews with young people, the authors aim to understand more about adolescent's attitudes to sexuality and their sexual behaviour in order to develop policies which will meet their needs more appropriately and effectively. Issues covered in this interesting and accessible book include the ways adolescent informal culture affects sex education programmes and practice; the impact of gender inequality on sex education and safer sex behaviours; legislation and policy frameworks which effect sex education policies; the way young people see legislation and evaluate sex education programmes; and the impact health professionals can have in school sex education. The authors contend that the insights into the values and views that young people bring to bear on the sex education they receive should have an important role to play in the development of policy and practice of those involved in sex education work.
