Sex education in the UK is a compulsory topic for Children aged 11 and up. It mainly involves teaching children about sexual health, reproduction, and sexuality. Its aim is not to promote early sexual activity or to promote specific sexual orientations, but to educate children about different types of sexuality to help them understand and accept themselves and others, whilst also learning to be prepared and understand the consequences of improper sexual activity in the future.
Parts of sex education is compulsory, like reproductive health in biology, but other parts are optional and parents can withdraw their children from it.
The Education Act of 1996 requests for students to be taught about STIs and HIV, as well as encourages pupils to discuss moral considerations and family life. Thus, it is compulsory for schools to inform and teach students about the biological aspects that surround puberty, reproduction and the spreading of infections.
The broader subject of sex and relationships is not compulsory in schools, however schools are recommended to offer help and guidance on the topic as part of the PSHE curriculum. Many schools within the United Kingdom do cover many subjects that surround sex and relationships.
Parents do have the right to withdraw their children from being taught about sex and relationships outside of the scientific curriculum, however cannot request for their child not to be taught about the scientific aspects of it.
