Sex education in Year 5 helps pupils begin to understand puberty, body changes and growing up in a calm, age-appropriate way. In many primary schools, this learning sits within a wider PSHE and RSE curriculum so that pupils can explore new ideas with clear language, trusted adults and well-sequenced teaching.
Sex education in Year 5 often marks the point where puberty is introduced more directly within the primary curriculum. By this stage, pupils have usually already explored themes such as friendships, respect, personal space and growing up through earlier PSHE and relationships education lessons. Year 5 then begins to build on that foundation with a clearer introduction to body changes, hygiene and the emotional side of puberty.
In many schools, this learning is taught carefully within a wider PSHE and RSE programme rather than as a separate block of teaching. This helps pupils approach the topic gradually and gives teachers space to explain new ideas in a calm, age-appropriate way. In England,
relationships education is compulsory in primary schools, and the statutory guidance also includes teaching about puberty and the changing adolescent body during the later primary years.
At this stage, lessons often focus on helping pupils understand what puberty is, why body changes happen and how children can look after themselves as they grow older. Many schools also begin preparing pupils for the more detailed learning that may follow in Year 6. The 2026 statutory guidance explains that schools may choose to teach sex education in Years 5 and 6, although sex education itself is not compulsory in primary schools.
Year 5 is often the point where schools begin to introduce puberty more directly. Some pupils may already be noticing physical or emotional changes, while others may simply be becoming more aware of the topic through their peers, older siblings or the wider world around them. A thoughtful Year 5 approach helps pupils feel informed before changes become more personal or immediate.
The science curriculum for Years 5 and 6 says pupils should learn to describe the changes as humans develop to old age, and the non-statutory notes say pupils should learn about the changes experienced in puberty. That makes Year 5 a sensible and natural point to begin or revisit this learning in a careful way.
This is also why Year 5 lessons should not focus only on physical development. NHS guidance explains that puberty can bring emotional changes as well, including stronger feelings and increased self-awareness. Helping pupils understand this early can reduce uncertainty and support wellbeing.
This is a common question for schools and parents.
Sex education is not compulsory in primary schools in England. However, all primary schools must teach relationships education, and state-funded schools must also teach health education. Parents can request withdrawal from some or all sex education taught beyond the science curriculum.
Even so, many schools choose to include sex education in Year 5 because it helps pupils understand puberty in an age-appropriate way and prepares them for later learning. Government curriculum planning guidance also makes clear that schools have flexibility to design and sequence this teaching according to the needs of their pupils and community.
A strong Year 5 programme introduces these topics carefully and at the right stage. The goal is to help pupils feel ready, safe and able to ask sensible questions.
Puberty is usually the central theme in sex education Year 5 lessons. Pupils may learn about body hair, growth spurts, changing body shape, periods, wet dreams and other signs of development. NHS guidance explains that puberty starts at different ages for different children, which helps pupils understand that growing up does not happen at exactly the same time for everyone.
Year 5 lessons often include practical teaching about hygiene and self-care. This may cover washing, deodorant, changing clothes, periods and general body care during puberty. This kind of teaching helps pupils feel more confident and less anxious about the practical side of growing up. The statutory guidance specifically includes teaching about health, puberty and the changing adolescent body from age 9 to 11.
Pupils also benefit from learning that puberty affects thoughts and feelings as well as the body. Lessons may explore mood changes, privacy, self-image and when to seek support from a trusted adult. This fits naturally within a wider wellbeing-focused curriculum and links closely to the emotional development already seen in good PSHE teaching.
Year 5 is also a good stage for strengthening learning around privacy, respect and personal boundaries. Pupils need simple, clear teaching that helps them understand safe and unsafe situations and where to go for help. Safeguarding remains an important background principle here, and this sits closely alongside wider relationships education. The guidance also emphasises teaching children how to ask for help, how to keep trying until they are heard, and where to get advice.
Year 5 sex education should act as a bridge. It should build on earlier KS2 learning and prepare pupils for the fuller teaching that often comes in Year 6. In lower KS2, pupils usually begin with friendships, personal space, growing up and respectful relationships. In Year 5, schools often introduce puberty more directly. In Year 6, this learning may develop further into clearer teaching about reproduction and transition to secondary school.
That sequence matters. Government planning guidance says schools should create an RSHE curriculum that is tailored, well planned and suitable for the age and maturity of pupils.
You can explore that wider progression in our guides to sex education in KS2, sex education in Year 6 and sex education in Year 3 and Year 4.
For many families, Year 5 is the stage where questions about puberty become more immediate. Clear school communication makes a big difference. Parents and carers should understand what will be taught, why it is being taught and how lessons are adapted to the age of the class.
The
Sex Education Forum’s Young People’s RSE Poll 2025 found that 52% of young people rated their RSE as good or very good, which underlines the importance of thoughtful teaching and strong support for schools. For families who want help continuing conversations at home, the NSPCC also provides guidance on talking about sex and relationships.
Effective sex education in Year 5 should be calm, factual and age appropriate. It should help pupils begin to understand puberty, care for themselves and recognise that growing up includes emotional as well as physical change. Just as importantly, it should help pupils feel comfortable asking sensible questions and seeking support when they need it.
When this learning sits within a wider PSHE and RSE curriculum, pupils can connect it to earlier lessons on friendships, self-respect, wellbeing and safety. For schools reviewing their wider provision, our guides to
what is RSE in education and the
PSHE curriculum in KS2 can help place Year 5 sex education within the bigger picture.
