School Age FAQ
Everything you need to know about the UK school admission system, cut-off dates, and year groups.
In England and Wales, the school admission cut-off date is 31st August. Children are placed in school years based on the academic year in which they turn 5. This means a child born between 1st September and 31st August will be in the same school year cohort. Note that Scotland uses a 1st March cut-off, and Northern Ireland uses a 1st July cut-off.
Children in the UK typically start Reception in the September after their 4th birthday. For example, a child born in 2019 will start Reception in September 2023. They will be 4 years old when they start, and turn 5 during that academic year.
Chronological age is the exact time since birth. School year age groups children by the calendar year they turn 5. Because of the 1st September cut-off, a child born in July could be almost a year younger than a classmate born in September, even though they are in the same school year.
Children in the UK typically start secondary school (Year 7) in the September after their 11th birthday. This is exactly 7 years after they started Reception.
Students typically start their 2-year GCSE courses in Year 10 (age 14-15) and take exams in the summer of Year 11 (age 15-16). A-Level or Sixth Form courses start in Year 12 (age 16-17) and exams are taken in the summer of Year 13 (age 17-18).
Yes, if your child is born between 1st January and 31st August (a ‘summer-born’ child), you can request to defer their entry until later in the school year, or request part-time attendance until they reach compulsory school age. However, they cannot defer beyond the start of the final term of the Reception year.
In England, the compulsory school age is the start of the term following a child’s 5th birthday. However, practically all children start school full-time in the September after their 4th birthday. The law requires young people to stay in education or training until the end of the academic year in which they turn 18.
School years in England and Wales are grouped by the academic year running from 1st September to 31st August. Children born in the same academic year are placed in the same year group, starting with Reception, followed by Year 1 through to Year 13.
