British schools are renowned worldwide for the quality of the education they offer. However, the way the system works is often confusing for families. In this article, we’ll walk you through the UK school system at every age – covering the key exams, entry points, and comparisons with the US grading system.
The UK system is unique, and is made more complex by the fact that the state sector and the independent (private) sector don’t always use the same terminology for the same stage of education. A prep school, for instance, means something quite specific in the UK – and has nothing to do with how the term is sometimes used in the US. Meanwhile, exams like the 7 Plus, 11 Plus, and 13 Plus are largely a feature of the independent and grammar school world, and rarely come up if you’re only familiar with state education.
This guide is designed to make sense of all of it.
Note: there are four nations within the UK: England, Wales, Scotland, and Northern Ireland. They each have their own school systems. For the rest of this guide, we’ll be focusing on the system used in England, which is broadly similar to the one also used in Wales.
Overview of the UK School System at Each Age
To begin with, we’ve prepared a full reference table showing how age, year group, school type, and exams all line up – followed by a detailed, age-by-age breakdown explaining exactly what happens at each stage, and what to look out for if you’re planning ahead.

UK School Ages Explained: Year by Year
How to Read This Guide
In the UK, children start school in the September after their fourth birthday. This is why the key date to remember is 31 August: your child’s age on this date usually determines which school year they’re in, regardless of when in the year they were born.
The school year runs from September to July, split into three terms: autumn (September–December), spring (January–March), and summer (April–July).
One thing to flag before diving in: school “types” aren’t always as neatly separated in practice as the table above suggests. Especially in the independent sector, it’s common to find combined pre-prep and prep schools, combined prep and senior schools, or “through-schools” that take children from nursery all the way to Year 13. Don’t be surprised if a school doesn’t fit a single category – although the school may well still use these labels to refer to its internal divisions: “our prep pupils”, “the teachers in our senior schools”, “our sixth form” etc.
Under 4: Nursery
Most children attend some form of nursery before starting formal schooling. For families considering the independent sector, this is also when the 4 Plus assessment comes into play if you’re applying to a selective pre-prep school. It’s taken during the school year before your child starts Reception – so if your child started the school year aged 3, this is their 4 Plus year.
If your child might have a 4 Plus assessment coming up, you may like to learn about our 4 Plus tutoring – gentle, play-based prep from early years experts.
Age 4-5: Reception
Reception is when most children begin school. In the state sector, Reception marks the start of primary school; in the independent sector, children start pre-prep in Reception. (You can learn more about the differences between state and private schools in our dedicated article.)
Many independent schools combine pre-prep and prep into a single school (typically covering Reception through Year 6), and some also have a nursery attached, meaning it’s common for a child to stay at one school from age 2 or 3 right through to age 11.
Age 5-6: Year 1
Children move from the Early Years Foundation Stage (EYFS) – which covers birth to age 5 – into Key Stage 1. This marks the beginning of the National Curriculum’s more structured academic stages, though at this age the difference feels subtle day to day.
Age 6-7: Year 2
For families considering prep schools, this is when the 7 Plus exam typically takes place, assessing children for entry the following September.
If your child is preparing for the 7 Plus, you may be interested in our 7 Plus tutors.
Age 7-8: Year 3
A year of several transitions at once:
- Children begin Key Stage 2.
- This is the first year of prep school in the independent sector.
- If your child sat the 7 Plus last year and received an offer, this is the year they start at their new school.
Some prep schools also hold 8 Plus entrance exams this year, for children joining the following September.
Worth noting, too: some independent schools combine prep and senior into one continuous school, so some children will stay at the same school from age 7 to 18.
Age 8-9: Year 4
Children who were successful in the 8 Plus process start at their new prep school this year.
Age 9-10: Year 5
There are no common entry points, exams, or other transitions held in Year 5. However, many families choose to begin preparation for the 11 Plus (taken in Year 6) at this point, if applicable.
Age 10-11: Year 6
One of the busiest years for exams and decisions:
- The 11 Plus is held for entry into senior independent schools and grammar schools (selective state schools, which exist only in certain parts of the country).
- Many children also sit pre-tests for the 13 Plus this year – commonly the ISEB Common Pre-Test – used by senior schools to assess candidates well ahead of formal 13 Plus entry.
Our article on how to pass the 11 Plus contains in-depth advice on what the exam involves and how to prepare. You may also like to read our list of 11+ interview questions, with guidance on what senior schools are looking for at interview.
At Dukes Tutoring, we offer one-to-one 11 Plus tuition with hand-picked, highly experienced tutors. Every year our tutees get into the leading senior schools in London and the rest of the UK – and 98% receive an offer from one or more of their first-choice schools.
Age 11-12: Year 7
Children begin move into secondary education and begin Key Stage 3. In the state sector, this always means starting secondary school. In the independent sector, it’s more nuanced:
- The vast majority of girls’ senior schools take pupils from Year 7.
- Traditionally, boys’ senior schools started in Year 9, with prep school running through Year 8 – and some of the most well-known names (Eton, Harrow, and Winchester, among others) still follow this pattern. (Learn more about applying to Eton here.)
- Many boys’ senior schools now also take pupils from Year 7
This means families with sons often face a choice between a Year 7 entry senior school and a more traditional Year 9 entry one – which affects when (and whether) the 13 Plus is relevant to them. You can learn more about how to choose a school in our dedicated article.
Age 12-13: Year 8
For boys heading toward a Year 9 senior school start, this is the year they sit the 13 Plus. The 13 Plus usually requires children to sit exams in more subjects than the 7+ or 11+, often including science, a modern and/or classical language, and humanities as well as English and Maths.
If you’d like 1-1 preparation for your child, you may be interested in our 13 Plus tutors.
Age 13-14: Year 9
Children who took the traditional 13 Plus route start senior school this year – historically the standard entry point for boys’ schools, though as noted above, this is now just one of two common pathways.
At this point, children will choose the GCSEs they will take for the next two years.
Age 14-15: Year 10
Year 10 marks the beginning of Key Stage 4. In Year 10, children begin studying for their GCSEs, with exams sat in the summer of Year 11.
Age 15-16: Year 11
GCSE exams are sat this summer – the first major set of public examinations in a UK child’s education.
We offer the highest standards of GCSE tutoring in all major subjects, and can arrange short-term programmes of revision or booster tuition, or long-term support during the entirety of the GCSE curriculum.
Families considering a move to an independent school for sixth form will typically have their child sit the 16 Plus this year, as part of the application process.
In Year 11, children also select their A Level subjects which they will study for the next two years.
Age 16-17: Year 12
The start of sixth form (Years 12 and 13) brings some of the most varied pathways in the whole system:
- Many state secondary and independent senior schools run all the way through to Year 13 – allowing students to stay put.
- Some schools, however, stop at Year 11, meaning students need to move elsewhere for sixth form.
- There are also dedicated sixth form colleges, in both the state and independent sectors, which some students join fresh at 16.
- To complicate things further, many colleges now also admit students from Year 10, effectively offering a four-year GCSE-to-A-Level pathway.
Academically, this is the first year of Key Stage 5, and the beginning of study for A Levels or the IB Diploma Programme, both examined at the end of Year 13.
Other options for post-16 education include vocational qualifications like T Levels and BTECs, as well as leaving school and doing an apprenticeship.
Age 17-18: Year 13
Year 13 marks the final year of school for most children. Students sit their A Levels (or complete the IB Diploma) in the summer, marking the end of the UK school system, and the transition to university or other next steps.
At Dukes Tutoring, our A Level tutors provide 1-1 private tuition for all major A Level subjects – whether you’re looking for long-term support throughout the curriculum or a short-term programme of revision or booster tuition in the final stretch before exams.

FAQs
At what age do you start school in the UK?
In England, most children start Reception in the September after their fourth birthday. They are usually aged four when they begin and turn five during the school year. However, compulsory school age does not begin until the school term after a child’s fifth birthday.
What are the different school years and ages in the UK?
In England, the usual school year groups and ages are:
Nursery: ages 3–4
Reception: ages 4–5
Year 1: ages 5–6
Year 2: ages 6–7
Year 3: ages 7–8
Year 4: ages 8–9
Year 5: ages 9–10
Year 6: ages 10–11
Year 7: ages 11–12
Year 8: ages 12–13
Year 9: ages 13–14
Year 10: ages 14–15
Year 11: ages 15–16
Year 12: ages 16–17
Year 13: ages 17–18
Usually, the child’s age on the 31st August decides which year they are in (e.g. a child who is 11 on the 31st August will start Year 7 in September).
When do children take the 4 Plus, 7 Plus and 11 Plus?
Children usually take:
The 4 Plus in nursery (age three or four) for entry into Reception
The 7 Plus in Year 2 (age six or seven) for entry into Year 3
The 11 Plus in Year 6 (age ten or eleven) for entry into Year 7
These assessments are normally taken during the school year before the child joins their new school. The names generally refer to the age at the entry point rather than the child’s exact age on the day of the test.
What age are children when they take GCSEs?
In England, most children take their GCSE examinations in Year 11, when they are aged 15 or 16. GCSE courses usually begin in Year 10, although some schools start teaching parts of the curriculum earlier.
What is the youngest you can leave school?
In England, you can leave school on the last Friday in June if you will be 16 by the end of that year’s summer holidays. However, you must remain in education or training until you turn 18. This could mean attending college, completing an apprenticeship, or working while undertaking part-time education or training.
How do UK school system ages compare with the US?
In England, Reception at ages four to five is broadly equivalent to US Pre-K, while Year 1 at ages five to six is equivalent to Kindergarten. From Year 2 onwards, the English year group is generally one number higher than the equivalent US grade: Year 2 corresponds to Grade 1, Year 7 to Grade 6, and Year 13 to Grade 12. These comparisons are approximate because school-entry cut-off dates vary between US states and school districts.
School year names, starting ages and education rules differ in Wales, Scotland and Northern Ireland; the answers above describe the system in England.
