Tiffin Boys and Tiffin Girls in Kingston are among the most oversubscribed schools in the country. Over 2,000 children typically sit the test for roughly 150 places at each school. That's less than 10% getting in.
If you're reading this, you probably already know that. What you want to know is whether your child has a realistic shot and what you should actually be doing about it.
What the Tiffin test covers
Tiffin runs its own exam, separate from GL or CEM. The format has changed a few times over the years, which is part of what makes it tricky to prepare for. As of recent years, the test covers English and maths, with some verbal reasoning elements woven in.
The maths is where most children come unstuck. Tiffin papers tend to favour multi-step problems where the answer method isn't obvious from the question. Knowing your times tables is necessary but nowhere near sufficient. Your child needs to think around corners.
English is comprehension-heavy. They're not testing fancy vocabulary or creative writing. They want to know if your child can read a passage quickly, understand what it's really saying, and answer questions accurately under time pressure.
How competitive is it, honestly?
Very. But "very competitive" doesn't mean "impossible." It means that a lot of bright, well-prepared children won't get in purely because there aren't enough places. That's worth sitting with for a moment before you pour six months of your family's evenings into preparation.
If your child is comfortably in the top 5-10% of their class, they're in the right ballpark. If they're solidly average, Tiffin is probably not the right target, and that's fine. There are excellent schools that don't require this level of competition.
When to start
If Tiffin is your main target, starting in Year 5 is realistic. If you're also looking at independent schools with separate entrance exams, you'll want to get going in the summer after Year 4.
By autumn of Year 6 you should be doing 20-30 minutes most days. That's not something you can cram into the last term. The children who do well at Tiffin have typically been doing steady, regular practice for at least a year. Not marathon sessions. Just consistent.
What actually works
Past papers are your foundation. Tiffin publishes sample papers on their website. Use those first to understand the format and timing. The first time your child does a full paper, sit with them, time it, and go through the answers together. The marking matters more than the score.
For maths, build a daily habit: 10-15 minutes of problem-solving questions where the method isn't handed to them on a plate. If they can solve it by plugging numbers into a formula, it's too easy for Tiffin prep.
For English, it's about speed and stamina. Start with shorter timed passages (15-20 minutes) and build up. The children who struggle aren't usually bad readers. They're slow readers who run out of time.
Reasoning prep transfers well from GL-style papers, so if you've got those lying around, they're useful.
The burnout trap
Because Tiffin is so competitive, parents often overdo it. I get it, the stakes feel high. But two hours of focused, marked practice will always beat four hours of miserable slogging.
If your child starts dreading practice, you've already lost the psychological edge. The confidence hit from over-preparation is real, and it shows up on exam day.
A tutor who knows the Tiffin format specifically can be worth the money (emphasis on "specifically" - a generic 11+ tutor won't know what Tiffin papers actually look like). But one session a week with targeted homework is plenty. Don't let anyone convince you that three sessions a week is necessary.
The bit nobody talks about
Most children who sit the Tiffin test won't get in. That's just maths. And if your child doesn't get a place, it says nothing about how smart they are or how well you prepared them. It means there were more strong candidates than places.
Have a plan B that you're genuinely happy with. If you don't, the pressure on your child becomes unfair, and they'll feel it even if you think you're hiding it well. (You're not. They always know.)
Tiffin isn't magic. Kids get in every year by doing solid, steady preparation without destroying their family life in the process. If your child is in the right ability range and you build a sensible practice habit from Year 5, you're giving them a proper shot. That's all any of us can do.
