13+ Common Entrance Explained: What It Tests

📖 9 min read 👪 For parents & students 🏫 The exam that usually isn't the real decision 📅 Updated August 2026

Here's the detail that surprises most families new to independent school admissions: by the time a child sits 13+ Common Entrance in Year 8, the real decision about their senior school place has often already been made — around age 11, quietly, through registration and a pre-test. Common Entrance is widely assumed to be the main selection hurdle. For most children, it's actually confirming a place that's already effectively theirs, provided they clear the required standard.

This guide covers what Common Entrance actually tests, when it's sat, how pass marks work, and why understanding the pre-testing system matters more than the exam itself for most families.

A note on accuracy: Common Entrance is set and administered by ISEB (the Independent Schools Examinations Board) and used by around 170 independent senior schools, but individual schools set their own pass requirements and some highly selective schools use their own papers instead. Figures below are general patterns, not universal rules — always confirm directly with your target senior school.

Core factCE in Year 8 usually confirms a place already offered around age 11, not decides it

Key takeawayThe real competitive selection often happens years before the exam most families focus on

Quick tips:

Find out whether your target school uses pre-testing at 11 before assuming CE at 13 is the main hurdle.
Confirm which subjects and difficulty tier your target school actually requires — not every school needs every paper.
Ask your target school directly for its typical required standard — there's no single national pass mark.

Papers are set at up to three difficulty levels, so the same subject can be pitched differently depending on the senior school's academic level — a more selective school may require a higher tier paper in core subjects. Science is typically examined as a single integrated paper covering Biology, Chemistry and Physics rather than as three separate subjects.

The part most families miss: pre-testing decides more than CE does

Many independent senior schools don't wait until Year 8 to make their real decision. Instead, families register years in advance, and the child sits a pre-test — commonly the ISEB Common Pre-Test, an adaptive, computer-based assessment usually sat around age 10-11. Based on pre-test performance (often alongside a school report and sometimes an interview), the senior school makes a conditional offer well before Year 8.

Common Entrance in Year 8 then serves a different purpose than most families assume: it confirms the child has reached the required academic standard to take up the place already conditionally offered. For a child who's performing consistently, CE is a confirmation step, not a fresh competitive round against a whole new applicant pool.

Why this matters practically: if the real decision point is a pre-test around age 10-11, focusing all preparation energy on Year 8 Common Entrance specifically — and treating the years before as low-stakes — risks missing the assessment that actually matters most for many senior schools.

How the pass mark actually works

There's no single, fixed, nationally published pass mark for Common Entrance. Each senior school sets its own required standard, commonly reported in the region of 55-80% depending on how academically selective that school is, and requirements can vary by subject. A school that's already made a conditional offer via pre-testing may apply a more lenient standard than one using CE as genuine open competition — always confirm the specific expectation directly with your target school.

Parent advice

Ask directly whether your target school pre-tests, and when. This single question reveals whether the real decision point is age 10-11 or genuinely Year 8, and should shape your entire preparation timeline.

Confirm exactly which subjects and tier your target school requires. Preparing for all eight Common Entrance subjects when a school only requires three wastes real time and adds unnecessary pressure.

Don't treat Common Entrance as low-stakes just because a conditional offer exists. The standard still needs to be met — a conditional offer isn't unconditional, and genuine preparation for CE itself still matters.

Student tips

If your school already made you a conditional offer earlier on, Common Entrance is your chance to show you've kept up the standard that got you that offer in the first place — take it just as seriously as if it were the main exam, because in a real sense, it still is. Focus your preparation on the specific subjects your target school actually requires, and ask your current teachers which ones matter most for your situation.

Tutor notes

Establish early whether a family's target schools pre-test — this fundamentally changes the preparation timeline and where the real pressure point sits.
Confirm subject and tier requirements per target school before building a preparation plan — Common Entrance's flexible, modular structure means generic "cover everything" preparation is inefficient.
Reinforce that a conditional offer is not a guarantee with families who may be tempted to ease off after an early pre-test success — the required CE standard still needs to be met.

So what should you actually do?

Contact your target senior school directly and ask three things: do they pre-test (and if so, roughly when), which specific Common Entrance subjects and tier they require, and what standard they typically expect. These three answers replace guesswork with an actual, school-specific preparation plan.

Whether the real decision point turns out to be age 11 or Year 8, the underlying preparation that helps is the same: consistent, genuine skill-building over time, not a late scramble once the exam itself is imminent — the same principle that holds true across every stage of UK school entrance testing.

Frequently asked questions

What subjects does 13+ Common Entrance cover?

Common Entrance covers up to eight subjects: English, Mathematics, Science, French, Latin, Geography, History and Religious Studies. English, Maths and Science are the core papers almost every candidate sits; modern languages, classics and humanities papers are typically optional depending on the senior school's requirements.

When is 13+ Common Entrance actually sat?

Common Entrance at 13+ is sat in May or June of Year 8, when candidates are aged 12-13. This is later than many families expect, and later than the point at which the real admissions decision is often already made — see the note on pre-testing below.

Is Common Entrance the exam that decides whether a child gets into their senior school?

Often not, in practice. Many independent senior schools make their real selection decision earlier, around age 11, through registration and a pre-test (commonly the ISEB Common Pre-Test) — offering a conditional place at that point. Common Entrance in Year 8 then confirms that the child has reached the required standard to take up the place already offered, rather than being the primary competitive selection round itself.

What pass mark does a child need in Common Entrance?

There's no single national pass mark — each senior school sets its own required standard, commonly reported in the region of 55-80% depending on the school's selectivity, and can vary by subject. Always confirm the specific requirement with your target senior school directly.

Do all independent senior schools use Common Entrance?

No. Common Entrance is used by around 170 independent senior schools, but some of the most academically selective schools set their own entrance papers instead of relying on the shared CE format — always check which specific assessment your target school actually requires.
