In England, children are placed in year groups by their age at the start of the school year on 1 September, while Hong Kong usually groups children by calendar year of birth. As a result, most Secondary 1 (S1) students match Year 8, but those born between September and December match Year 7. GCSEs are taken at the end of Year 11, and A-Levels or the IB in Years 12 and 13. The school makes the final placement decision.
One of the most common questions from Hong Kong parents is simple: my child is in Secondary 1 now, so which year would they join in the UK? Because the two systems divide year groups differently, the answer often depends on your child's birth month. This guide uses the system in England (Scotland and other parts of the UK differ) to explain how the years compare.
England: year groups start on 1 September
The school year in England starts in September. Children born between 1 September and 31 August the following year are placed in the same year group, so a child's age at the start of the school year decides their year.
- Year 7: age 11 at the start of the year, usually the first year of secondary school
- Year 9: age 13 at the start of the year, the traditional 13+ entry point for many independent senior schools
- Year 11: age 15 at the start of the year; GCSE exams are taken at the end of this year
- Years 12 and 13: the sixth form, starting at ages 16 and 17, when students take A-Levels, the IB Diploma or similar courses
What are Key Stages?
The national curriculum in England is organised into Key Stages: Key Stage 1 (Years 1 to 2), Key Stage 2 (Years 3 to 6), Key Stage 3 (Years 7 to 9) and Key Stage 4 (Years 10 to 11, the GCSE years). Years 12 and 13 are usually called the sixth form. Independent schools do not have to follow the national curriculum, and some traditional schools use their own names, such as Lower Sixth and Upper Sixth, but the age groupings are broadly the same.
Hong Kong: usually grouped by calendar year of birth
The Hong Kong school year also starts in September, but entry to Primary 1 is generally based on the calendar year of birth (January to December). Students then complete six years of primary school and six years of secondary school, from S1 to S6, and take the Hong Kong Diploma of Secondary Education (HKDSE) in S6. Because the cut-off dates differ, children from the same Hong Kong class can fall into two different UK year groups.
Quick comparison: which UK year is S1?
The list below assumes your child started Primary 1 at the usual age and has not skipped or repeated a year.
- P6: Year 7 if born January to August; Year 6 if born September to December
- S1: Year 8 if born January to August; Year 7 if born September to December
- S2: Year 9 or Year 8
- S3: Year 10 or Year 9
- S4: Year 11 or Year 10
- S5: Year 12 or Year 11
- S6: Year 13 or Year 12
In short, most S1 students are the same age as Year 8 pupils in England, while those born between September and December line up with Year 7.
Why the final placement may differ
Schools decide placement based on date of birth, academic level, English ability and how well the student's previous studies fit the new course. GCSE and A-Level courses both run over two years, so students normally join at the start of Year 10 or Year 12, and schools generally discourage joining in the second year of a course. Some students are placed a year lower to allow time for English or curriculum adjustment, and some schools offer one-year programmes before GCSE or sixth form. Treat the comparison as a starting point and confirm placement with each school.
Common entry points
- 11+ (Year 7): a main entry point for many independent senior schools
- 13+ (Year 9): a key entry point for traditional boarding schools; some schools pre-test candidates at around age 10 to 11, and some use the ISEB Common Entrance examinations
- 14+ (Year 10): the start of GCSE courses
- 16+ (Year 12): entry to the sixth form for A-Levels or the IB
Because 13+ assessments can take place two years or more before entry, families aiming for this point should plan early. For other factors in choosing a school, see Choosing a UK Boarding School.
GCSE, A-Level, IB and the HKDSE
GCSEs in England are graded from 9 to 1, with 9 the highest, and many independent schools also offer IGCSEs. Most A-Level students take three subjects, graded A* to E, while the IB Diploma combines six subjects with a core programme. The HKDSE combines core subjects with electives. Many UK universities accept the HKDSE, though requirements vary by course. Our guide to A-Level, IB and foundation routes compares the options in more detail.

Frequently asked questions
Which UK year group is Secondary 1 (S1) in Hong Kong?
Most S1 students born between January and August match Year 8 in England, while those born between September and December match Year 7. The school makes the final decision on placement.
When do students take GCSEs and A-Levels?
GCSEs are usually taken at the end of Year 11. A-Levels, or the IB Diploma, are studied in Years 12 and 13, known as the sixth form.
What is 13+ entry?
13+ is entry into Year 9, a traditional entry point for many independent boarding schools. Some schools assess candidates around two years before entry, so it pays to plan early.
