ISEB pre-tests: a tutor's honest guide for parents

If you've just found out your child's senior school uses the ISEB pre-tests, you probably have more questions than answers. I'm Anmol Jinger, and I tutor Maths and Non-Verbal Reasoning one-to-one online, so I sit with worried parents about this every week. Here's the plain version, from someone who prepares children for these tests.

What are the ISEB pre-tests?

The ISEB pre-tests are a set of four short online assessments run by the Independent Schools Examinations Board. Your child takes them on a computer, and every question is multiple choice.

The word that matters most is adaptive. The software adjusts to how your child is doing: get a question right and the next one gets a little harder; slip up and it eases off before building again. Everyone starts around the middle, so no two children see exactly the same paper. One catch that surprises families every year — there's no back button. Once your child moves on from a question, it's gone. They can't return to check it later, so a calm, considered first answer beats a rushed guess.

The four sections are Maths, English, Verbal Reasoning and Non-Verbal Reasoning. Together they take a little over two hours, and a school can run them in one sitting or spread them across a few days.

Why the ISEB pre-tests matter

Years ago, a family applying to five schools might have faced five different entrance exams on five different Saturdays. The pre-tests were built to end that. Your child sits one assessment, and the result is shared with every participating school they've applied to. Less travelling, fewer early mornings, one set of nerves instead of five.

That convenience carries weight, though. For a lot of senior schools now, the pre-test is the first filter — the score that decides who's invited to an interview or an assessment day and who isn't. So while it's only one part of the picture, it's often the part that opens the door.

Results come back as an age-standardised score, not a raw mark or a percentage. That standardisation is deliberately fair: a child born in August is measured against other August-born children, not against a classmate who's nearly a year older. The average sits at 100. There's no fixed pass mark, and schools read the score alongside a reference from your child's current school, an interview, and sometimes their own paper — so a number on its own never tells the whole story.

Who the ISEB pre-tests are for

Most children sit the pre-tests in Year 6, usually in the autumn term, occasionally in the spring. Some schools use them for entry into Year 7, others for deferred entry into Year 9. Your target school's admissions page will say which applies, and it's worth checking early — registration windows close sooner than parents expect.

Here's a point I want to be honest about, because it causes real confusion. Common Entrance and the pre-tests are not the same thing, and Common Entrance no longer automatically follows. Plenty of senior schools, especially at 11+, now use the pre-test as their main academic filter and have dropped the old Common Entrance exam. Others, particularly for 13+ entry, still ask for it later. Don't assume either way — ask the school directly what they want after the pre-test, so you're preparing for the right finish line.

The content itself leans on the Key Stage 2 national curriculum — roughly what's been taught up to the end of Year 5 — with the two reasoning papers layered on top. So this isn't about pushing a child years ahead. It's about being secure and quick with material they've mostly already met.

What subjects do the ISEB pre-tests cover?

Four sections, each testing something a little different:

• Maths — arithmetic, fractions, problem-solving and the mental agility to work at pace.
• English — reading comprehension plus spelling, punctuation and grammar.
• Verbal Reasoning — word logic, patterns and quick thinking with language.
• Non-Verbal Reasoning — shapes, sequences and spatial puzzles with no reading involved.

One thing that reassures anxious children: the online platform has genuine accessibility options built in. The font size can be made larger, a coloured overlay can be switched on to reduce visual glare, and the countdown timer can be hidden if watching the clock tick down makes your child panic. If any of those would help, ask the school in advance so it's set up before test day.

How I help with the ISEB pre-tests

My focus is Maths and Non-Verbal Reasoning — the two sections where steady practice moves the needle most. Maths rewards accuracy under time pressure, and Non-Verbal Reasoning is a skill almost no child meets at primary school, so it can feel alien the first time they see it. Both respond really well to short, regular, one-to-one work.

In lessons I do three things. I get the underlying method solid, because a child who understands why doesn't fall apart when a question is dressed up differently. I teach the exam habits the adaptive format demands, like committing to a careful first answer and pacing without freezing. And I rebuild confidence, because a nervous child underperforms no matter how much they know.

Everything is online and one-to-one, so I shape each session around your child rather than a group. The first lesson is free — a proper lesson, not a sales pitch — so you can see how your child responds before committing to anything.

Common questions

Can you resit the ISEB pre-tests?

No. A child can only sit them once in an academic year, which is exactly why unhurried preparation beats last-minute cramming. There's no second attempt to fall back on.

What's a good ISEB pre-test score?

The average is 100, and more competitive schools often look for scores comfortably above that. There's no official pass mark, though, and every school sets its own bar — so treat any target number as a guide rather than something carved in stone.

Can my child use pen and paper?

Yes. The test is on screen, but children are given paper for rough working, which matters a lot for the Maths section. I make sure my students are comfortable jotting down working quickly while reading from a screen.

How early should we start preparing?

For a Year 6 sitting, giving yourself the year before makes life calm rather than frantic. A little and often, over months, beats intense last-minute pressure every time — and it's kinder on your child.
