The UK Intermediate Maths Challenge (IMC) is the one national maths competition that every KS3 year group can sit — it's open to all of Years 7, 8 and 9. Like its Junior sibling, it's a relaxed one-hour paper of 25 multiple-choice puzzles, taken in your child's own school. For a Year 9 who's outgrown the Junior Challenge, it's the obvious next step; for a keen Year 7 or 8, it's a stretch worth trying. Here's how it works and where it can lead.

What the Intermediate Maths Challenge is

The IMC is another of the UK Mathematics Trust's school competitions, and it looks a lot like the Junior Challenge: 60 minutes, 25 multiple-choice questions, sat on paper in your child's school.

The difference is who it's for. The Junior Challenge stops at Year 8; the Intermediate is open to Year 11 and below — which, crucially for us, means all three KS3 years qualify. A Year 7, a Year 8 and a Year 9 could all sit the very same paper.

That's not a mistake in the design. The IMC is pitched a little older, so the toughest questions are aimed at pupils in Years 10 and 11. But the paper still starts gently, and a younger, confident child loses nothing by having a go at the early questions and seeing how far they get.

Why it matters for Year 9

There's one group for whom the IMC is especially important: Year 9. In England, a Year 9 pupil is too old for the Junior Maths Challenge, so the Intermediate becomes their challenge — the competition that fits their year group exactly.

If your child enjoyed the Junior Challenge in Year 7 or 8, the IMC is how that thread continues rather than stopping dead. And because it's open to younger pupils too, a maths-loving Year 7 doesn't have to wait — they can try the Junior and Intermediate in the same season if their school enters both.

Facts at a glance

Intermediate Maths Challenge (IMC)
Who Year 11 and below — so all of KS3 (Years 7, 8 and 9) can enter
Format 60 minutes, 25 multiple-choice questions
When Usually late January. The 2026 paper ran on 28 January; the next is scheduled for 27 January 2027 — confirm the date with your child's school
How to enter Through your child's school only; around £15–£16 per 10 pupils
Awards Certificates for top performers, plus invitations to follow-on rounds (see below)

As with the Junior Challenge, you can't enter your child directly — it's a school-entry competition, so the first step is a quick word with their maths teacher.

What happens after — and the follow-on rounds

Strong IMC scores lead to two kinds of follow-on. The first is the Kangaroo rounds — for the IMC these are the Pink and Grey Kangaroo, an invitation-only paper (in 2026 it ran on 19 March). The second is the written Olympiad papers, which are split by year group:

  • Cayley — for Year 9 and below,
  • Hamilton — for Year 10,
  • Maclaurin — for Year 11.

For a KS3 family, the one to know is the Cayley Olympiad. It's the round a talented Year 9 (or younger) is invited to after a high IMC score, and it swaps multiple choice for a smaller number of longer, write-it-out problems.

Here's the honest and genuinely useful bit that isn't obvious: the Intermediate route is the one that actually points towards the top. The Junior Mathematical Olympiad is a lovely achievement, but it's a celebration in its own right — it doesn't feed onward. The pathway that leads, eventually, towards the International Mathematical Olympiad runs through the Intermediate Challenge → Cayley → the senior rounds. So if you have a child who's serious about competition maths for the long haul, the IMC and Cayley are the line to watch. We trace the whole ladder in the junior olympiad guide.

None of that is a reason to push. The vast majority of children sit the IMC, enjoy the puzzles, maybe collect a certificate, and move on — and that's a perfectly good outcome.

How to help, gently

The preparation advice is the same as for the Junior Challenge, because the skill is the same: spotting the elegant route. That grows from relaxed problem-solving over time, not from cramming.

  • Do a past paper together, untimed, for fun. UKMT publishes them. The point is familiarity, not a score.
  • Ask your child to explain their thinking on the questions they got right. Reasoning aloud is where the learning lives — it's the "show your working" habit a good tutor builds every session.
  • Keep it proportionate. A single January competition should sit inside a calm week. If your child's timetable is already full, protect the balance first — energy-aware tutoring exists precisely because tired brains don't learn.

FAQ

Can a Year 7 child really do the Intermediate Maths Challenge?

Yes — the IMC is open to all of Years 7 to 9, so a Year 7 pupil is eligible even though it's pitched a little older. The paper starts gently, and schools decide which pupils to enter. A younger child isn't disadvantaged by the rules; the harder questions are simply aimed at pupils above them.

What's the difference between the Junior and Intermediate Maths Challenge?

The Junior Challenge is for Year 8 and below; the Intermediate is for Year 11 and below, so all three KS3 year groups can sit it. Both are one-hour, 25-question multiple-choice papers. The Intermediate is the natural next step for a Year 9 who's too old for the Junior.

How does my child enter the Intermediate Maths Challenge?

Through their school, not directly. Ask their maths teacher whether the school runs it — most secondary schools do. Schools pay a small fee (around £15–£16 per ten pupils) and sit the paper on site.
