Stakeholders have suggested that well-taught RSE can improve public health, address inequalities, promote healthy relationships, and improve awareness of the risks posed by using digital technology. Many studies on RSE are international and there are relatively few that focus just on the UK. As RSE programmes historically focussed on public health outcomes (such as reducing the prevalence of sexually transmitted infections), more evidence is available on the effect of RSE on these outcomes than on others (such as reducing partner violence).

Key Points

  • Relationships and Sex Education (RSE) can increase knowledge about sexual risk, lead to increased use of contraceptives, and reduce young people’s number of sexual partners. Some evidence suggests that it may delay the point at which young people first have sex and decrease rates of teenage pregnancy. However, it is difficult to isolate the effect of RSE programmes on teenage pregnancy rates as studies often examine multiple interventions at the same time.
  • There are few high-quality studies on how RSE affects prevalence of sexually transmitted infections (STIs). However, available evidence suggests that RSE does not reduce STI rates among young people.
  • Evidence shows that RSE can increase young people’s knowledge about, and change attitudes towards, sexual abuse and partner violence. There is less evidence to show that RSE programmes change young people’s relationship behaviour.
  • RSE’s role in improving awareness of the risks of sharing nude images and using pornography has not yet been evaluated.
  • RSE is most effective when it is taught by trained professionals in regular sessions, delivers age-appropriate content, is inclusive of different sexual and gender identities, is embedded into school policy, and involves the input of young people and their families.
