At Lionheart, ISEB preparation starts from what your child can already do, and spends time only where the assessment shows it is needed.

Why the ISEB pre-test matters 

How schools use the result

Many independent senior schools use the ISEB Common Pre-Test as their first sift. Children who fall short are often out of the process before anyone at the school has met them. For some 13+ places, that happens in Year 6.

So the worry we hear most is a fair one. Two hours at a computer can count for more than everything else about your child.

The test adapts to every answer, so there are no papers to drill. What helps is secure reading and maths. Add a clear method for reasoning questions and some practice on screen. If your child already has most of that, we will say so and keep the preparation short.

Our Tutors

Who prepares your child

ISEB preparation is led by tutors who know senior school admissions well, and many have taught in independent schools themselves. Each tutor is matched to your child on subject strength and temperament. A ten-year-old who trusts their tutor will say when a question type has stopped making sense, and that is usually where the real progress starts.

Before tuition begins, we assess your child against ISEB Pre-Test standards, so the plan starts from where they are rather than from a generic syllabus.

Our Approach

How ISEB pre-test preparation works at Lionheart

The pre-test is a short, single sitting with a lot riding on it. We plan backwards from the date your senior school gives you.

  • Initial discussion & assessment

    Number 1

    We start with a conversation about your child and the schools on your list, then a diagnostic assessment benchmarked against ISEB Pre-Test standards. It shows which of the four areas need work and, just as usefully, which can be left alone.

  • Tutor matching and a dated plan

    Number 2

    We match your child with a tutor and build the plan around their sitting. Most children sit in Year 6 and many schools set autumn deadlines, so planning for most families begins in Year 5.

  • Foundations First

    Number 3

    The adaptive format rewards children who are secure rather than merely practised. Early sessions build comprehension, vocabulary, arithmetic fluency and a clear method for each reasoning question type.

    Our guide on how to prepare for the ISEB pre-test covers this stage in more detail.

  • Practice on Screen

    Number 4

    In the final weeks, preparation moves onto the screen: timed, multiple choice and without a calculator, finishing with a full-length mock sitting so the real test feels routine. Children also learn to keep going calmly when questions get harder, which in an adaptive online test usually means they are doing well.

  • Preparing for What Comes Next

    Number 5

    The pre-test is usually the first stage. Interviews, school reports and the school’s own assessments follow, and at 13+ there may be Common Entrance or scholarship papers later on.

    We prepare for the next stage alongside the pre-test, including mock interviews with former heads of leading independent schools for families who want them. Our article on what happens after the ISEB pre-test sets out the usual sequence.

Your ISEB Pre-Test questions answered

  • When do children sit the ISEB pre-test?

    Most children sit it in Year 6, and some schools test in Year 7. You register your child through ISEB’s Guardian Portal, and they sit it at an approved centre, which is often their current prep school. Testing runs from September to May, though many schools set autumn deadlines.

  • How early should we start preparing?

    Six to twelve months suits most children, and many need less. A child with secure English and maths may only need a term of focused reasoning work and practice on screen. We will give you an honest view after the initial assessment.

  • Can you really prepare for an adaptive test?

    Yes, though not by memorising questions. The test adjusts its difficulty to each answer, so good preparation strengthens the skills it measures and makes the format familiar. How difficult the ISEB pre-test feels depends largely on how secure those skills are going in.

  • Is the ISEB pre-test the same as the 11+?

    No. Grammar school 11+ exams are usually fixed papers. The ISEB pre-test is online, adaptive and used mainly by independent senior schools, for 13+ entry as well as 11+. Our comparison of the GL and ISEB pre-tests sets out the differences, and our 11+ tuition covers families preparing for both.

  • Can my child take the pre-test more than once?

    Children sit it once, and that result goes to every participating school you apply to. It is worth treating that sitting as the one that counts.

  • Does a strong score guarantee a place?

    No. Most schools use the result to decide who moves on to interview and further assessment, and read it alongside school reports and references. A strong score keeps doors open. It rarely decides the outcome by itself.
