Choosing a senior school in London is one of the biggest decisions a family makes. There are hundreds of options across the capital, from large day schools to small specialist colleges, and the best one for your child may not be the one with the loudest reputation.
This guide is for parents working out what to look for, and what questions are worth asking before you commit.
What is a senior school, and when do you choose one?
In England, senior school usually means the secondary years leading up to GCSEs. Many London families choose at 11 or 13, but plenty look again at Year 9 or Year 10, when it becomes clear that a child is not getting what they need from their current school.
That second kind of decision is more common than people admit. A child who coasted in a large class at 11 can feel invisible at 14. A move at that point is not a step back. It is a sensible response to what you are seeing.
What to look for in a senior school in London
The brochure will tell you about facilities and results. The questions that matter more are quieter ones.
How big are the classes? In a class of thirty, it is easy to get through a lesson without being noticed. In a class of nine, that is not possible.
Who is doing the teaching? Subject specialists who know their material well, and who enjoy teaching teenagers, make a visible difference.
Does the school know your child? Pastoral care is not an add-on. It is how a school spots a student who is struggling before it shows up in a grade.
Is there room for flexibility? Some students need a different pace, a different environment or a different way of learning. The best schools adapt around the student.
How far is the journey? A school that takes ninety minutes to reach each way will wear a teenager down, however good it is.
A senior school in Kensington: Collingham’s GCSE programme
Collingham has taught students in Kensington since 1975, and today has around 150 students across two sites. Its GCSE programme, which covers the senior school years from Year 9, is based at 16 Young Street, W8, a short walk from High Street Kensington station. The building was once the home of William Makepeace Thackeray, who wrote Vanity Fair there. It is a calm, collegiate setting rather than a conventional school campus.
Classes are capped at nine students, with an average of five. Teaching is delivered by subject specialists, and students are known by name by the staff who teach them. There is no uniform and no large year groups. Students are encouraged to think independently from the start, with pastoral support built into the week.
The college’s ISI inspection in January 2026 confirmed that all standards were met, with inspectors noting the strength of its personalised support.
Some students join in Year 9 or Year 10 for the full GCSE programme. Others come specifically to resit one or more GCSE subjects. Many arrive because a larger school was not working for them.
How to get a real feel for a senior school
Visit while lessons are running. Ask to speak to current students without a member of staff hovering. Ask how the school handles a student who falls behind, and how quickly.
At Collingham, families can meet Paul, Head of GCSE, at a small Head’s Coffee morning at the Young Street building. It is a conversation, not a presentation, with current parents and students on hand to answer questions honestly.
Is a smaller senior school the right choice?
It depends on the child. A very sociable student who wants big sports teams and a large cohort may be happier elsewhere. A student who learns best through discussion, who has been overlooked in a bigger class, or who needs a more personal approach often does far better in a small setting.
The best senior schools are honest about that. They would rather you chose the right place than the most impressive one.
