Comparing a UK school year with a Turkish one by age alone gives the wrong answer, because the system is built on key stages rather than on year groups. The university route that follows is at UK education guidance.
01
How does secondary education work in the UK?
The system is built on key stages rather than on year groups. GOV.UK places key stage 3 across Year 7 to Year 9, covering ages 11 to 14, and key stage 4 across the two years that follow, covering ages 14 to 16.
Matching a Turkish class to a Year is therefore done against the key stage rather than against age alone, and schools place a pupil on assessment as well as on date of birth.
02
What is a GCSE?
The GCSE is the national qualification taken at the end of key stage 4, and it closes compulsory secondary education. GOV.UK states that most pupils take GCSEs or technical qualifications at this stage of schooling.
Subjects are taken individually rather than as a single certificate, so a pupil's GCSE profile is a list of subjects and grades. That profile is what the next stage is chosen from.
03
What follows GCSEs?
GCSEs mark the end of compulsory secondary education, and after 16 a pupil moves onto a two-year programme preparing them for university. For pupils arriving from Türkiye that programme is A Levels or the International Baccalaureate.
A Level grades are what university entry requirements are written against, which is why the two years after 16 carry more weight in an application than the GCSE years do.
04
Which visa is needed for school in the UK?
The route for international pupils is the Child Student visa. GOV.UK opens it to children aged 4 to 17 who will study at an independent school in the UK, and it does not extend to state schools.

05
What matters when choosing a school?
The decisive item is the type of school, because the type determines both the curriculum followed and the visa route available. A Child Student visa is granted only for study at an independent school, not at a state school.
- School type — independent schools are the route for a Child Student visa.
- Curriculum — GCSE and A Level, or the International Baccalaureate.
- Boarding or day, and the guardianship arrangement where boarding.
- The key stage the pupil's current class corresponds to.
06
What does British Global do at this stage?
British Global plans the school process: it sets out the child's age, class level and goal in a written preliminary report, and shows which Year the current class in Türkiye corresponds to under the key stage system.
Immigration questions on a Child Student visa are referred to an adviser registered with the Immigration Advice Authority rather than answered here.
07
Frequently asked questions
Can an international pupil attend a state school?
The Child Student visa is granted for study at an independent school, so it does not cover a state school place.
What age does the Child Student visa cover?
GOV.UK opens the route to children aged 4 to 17 studying at an independent school in the UK.
Are GCSEs a single certificate?
No. Subjects are taken individually, so a pupil's result is a list of subjects and grades rather than one award.
