How to prepare for St Catherine's School 11+

The exam at a glance

For girls applying to join St Catherine’s School in Year 7 for September 2028, the entrance assessment is the ISEB Common Pre-Test. St Catherine’s senior school admissions information says Year 7 admission is by assessment in the Autumn Term for entry the following September, and the school’s published arrangements for the previous cycle show that 11+ candidates sat the ISEB Common Pre-Tests in October or November.

The Common Pre-Test is taken online and is adaptive, which means the level of difficulty changes according to how a child is doing. That matters for preparation: your child needs to be comfortable working on screen, reading carefully, and keeping a steady pace. Because the test is tightly timed, it is not just about getting questions right; it is also about moving on sensibly and not getting stuck.

For St Catherine’s, the tested subjects are:

Maths
English
Verbal Reasoning
Non-Verbal Reasoning

The school’s admissions page for the recent cycle also shows that assessment is not only the online test. External candidates were invited to an Experience and Interview Day, so parents should expect the admissions process to include a broader look at the child, not just test scores.

What the day looks like will depend on whether your daughter sits the ISEB test at St Catherine’s or at her current school if that school is registered to administer it. In practice, families should expect a computer-based test session, followed separately by any school-arranged interview or visit elements if invited. The best preparation is therefore twofold: build secure subject knowledge, and help your child feel calm and efficient using an on-screen, timed format.

Registration and key dates

St Catherine’s runs its own admissions process. The school’s senior school admissions page says that parents should register with the school for Year 7 entry, and the school then arranges the assessment process.

For the most recently published 11+ cycle on the school’s admissions page, the verified dates were:

Registration closing date: 30 October 2026
ISEB Common Pre-Test sittings: October or November 2026
St Catherine’s offered a sitting on: 18 November 2026
All tests to be completed by: 30 November 2026
External candidates’ Experience and Interview Day: 7 November 2026

Because you are planning for 2028 entry, these are not yet the live dates for your child’s year unless the school has since updated them. At the time of writing, the safest wording is that St Catherine’s typically assesses Year 7 applicants during the Autumn Term, with the ISEB Common Pre-Test usually taking place in October or November, based on the school’s published 2027-entry information.

Independent schools often ask for a registration form and a registration fee, and sometimes request a recent school report or details of the child’s current school. However, only use the current St Catherine’s form and checklist when the 2028 entry page appears, because schools can change exactly what they require from year to year.

If you want a simple way to keep track, bookmark The St Catherine's School 11+ guide (format, catchment, dates): /schools/st-catherines-school-2 and sign up for Free email alerts for this school's key dates: /school-alerts?school=st-catherines-school-2. Those are useful if you want a prompt as soon as the school publishes the next set of dates.

Who can apply: catchment and admissions

St Catherine’s School is an independent girls’ school, so there is no local-authority grammar-school style catchment system published in the sources reviewed. The school describes itself as a day and boarding school for girls aged 2–19, with Senior School entry from Year 7 and Sixth Form entry.

For Year 7 entry, the admissions route is by registration and assessment in the Autumn Term before entry. The school’s published admissions material for the recent cycle confirms that the process included the ISEB Common Pre-Test and, for external candidates, an Experience and Interview Day.

We did not find a verified published figure on the senior school admissions page for the exact number of Year 7 places offered for 2028 entry, nor a published catchment priority, pass mark or cut-off score. If you need those details, check the current St Catherine’s admissions page directly and contact the admissions team for the latest position.

For parents moving from a prep school, one practical point is that the ISEB Common Pre-Test is widely used by independent schools. That can make the process smoother if your daughter is applying to more than one school using the same assessment, but each school will still make its own decision based on its own admissions process.

A month-by-month preparation plan

The best timeline for an Autumn Term test is calm and steady. For most Year 5 children, there is no need for heavy preparation years in advance. A sensible plan is to build habits gradually, then add timed work nearer the test.

January to March in Year 5

Keep it light: around 1 to 1.5 hours a week in total is enough for most children at this stage. Focus on secure core skills in arithmetic, vocabulary, comprehension and mental maths. If your child has never seen verbal or non-verbal reasoning before, introduce them gently as puzzle types rather than as test pressure.

Read widely and discuss meaning, tone and inference.
Revise number facts, fractions, decimals and problem solving.
Start short reasoning exercises once or twice a week.
Build confidence using a computer for short question sets.

April to June in Year 5

Increase to about 1.5 to 2 hours a week. By now, your aim is breadth: make sure your child has met the common question styles across all four subjects. Do not worry yet about doing long timed papers every week.

Continue regular reading and vocabulary work.
Practise short maths sets with mixed topics.
Add short bursts of verbal and non-verbal reasoning.
Begin occasional timed mini-sections of 10 to 15 minutes.

July to August before Year 6

This is a good point to build familiarity with the online, adaptive feel of the test. Around 2 to 3 hours a week is usually realistic, spread over several short sessions rather than one long one.

Do mixed-subject practice to build switching skills.
Use on-screen practice where possible.
Teach a simple pacing rule: answer, decide, move on.
Review mistakes carefully, especially avoidable ones.

September in Year 6

This is the month to become more exam-specific. Increase to around 3 hours a week, depending on your child’s stamina and school workload. Start doing more timed work now, because pace matters in the ISEB Common Pre-Test.

Do short timed sets in all four subjects each week.
Practise logging in, reading on screen and answering without fuss.
Identify weaker areas and keep targeted revision short and focused.
Keep one session each week for confidence-building, not correction-heavy work.

October to the test window

In the final weeks, quality matters more than quantity. Stay at about 3 to 4 hours a week if your child is coping well, but avoid cramming. Two or three sharp sessions and one lighter review session are better than long, tiring blocks.

Use timed practice papers or section practice sensibly.
Revisit common errors and slow reading habits.
Keep school nights calm and routine.
In the last few days, reduce volume and focus on confidence.

A useful rule of thumb: start timed papers or timed sections about 6 to 8 weeks before the test window. Before that, untimed understanding is more valuable than racing.

Subject by subject: what to practise

Maths

For the ISEB Common Pre-Test, maths practice should cover secure Key Stage 2 skills with an emphasis on speed and accuracy. Children need confidence with arithmetic, place value, fractions, decimals, percentages, ratio ideas at a simple level, measures, geometry and word problems. Because the test is adaptive, encourage your child to stay calm if a question looks harder than expected.

Practise mental arithmetic daily in short bursts.
Use mixed-topic sets rather than studying one topic for too long.
Teach your child to spot the operation needed in word problems quickly.
Work on estimating to sense-check answers.

English

English preparation should centre on reading accuracy, comprehension and vocabulary. In an online, timed setting, children need to read carefully without losing pace. Practise retrieving information, making straightforward inferences, understanding vocabulary in context and noticing tone or purpose.

Read high-quality fiction and non-fiction several times a week.
Pause to ask what a word means in that sentence, not just generally.
Use short comprehension exercises under light time pressure.
Encourage complete, precise thinking even when the answer format is short.

Verbal Reasoning

Verbal reasoning rewards familiarity. The main task is not to memorise endless tricks, but to recognise common patterns quickly. Children should see a broad range of question types so they do not waste time working out what the task is asking.

Build vocabulary steadily.
Practise word relationships, letter patterns, codes, sequences and logical language tasks.
Keep sessions short and regular.
Review mistakes by type so weak areas become obvious.

Non-Verbal Reasoning

Non-verbal reasoning is often the least familiar subject, so steady exposure helps. Focus on visual patterns, shape sequences, rotations, reflections, codes and similarities or differences. Children improve most when they learn to describe what is changing from one shape to the next.

Teach a checklist: shape, size, position, number, shading, rotation.
Practise spotting one change at a time.
Use short timed sets to build visual speed.
Encourage neat, calm scanning rather than guessing in a rush.

Practice papers and mock exams

Practice papers work best when they are used as a diagnostic tool, not just as a score-chasing exercise. For an adaptive online test, it is especially important to combine paper-based familiarity with on-screen confidence.

Start with untimed or lightly timed work so your child understands the question types.
Move to timed sections before attempting full mixed practice.
After every paper, spend longer reviewing errors than marking the score.
Track patterns: is the problem maths content, reading speed, vocabulary, or rushing?
Repeat weak question types after a few days, not immediately.

Use these school-specific ElevenReady resources as part of that plan:

Free email alerts for this school's key dates: /school-alerts?school=st-catherines-school-2

If you use a mock, treat it as a rehearsal of habits: logging in calmly, settling quickly, managing time and recovering after a difficult question. One well-reviewed mock can be more useful than several done back-to-back without reflection.

On the day

Children usually do best when the day feels ordinary and predictable. Aim for a calm start, a familiar breakfast and plenty of time to arrive or log in without hurry.

Check practical details the day before: time, location, device arrangements if relevant, and any instructions from the school.
Avoid last-minute teaching on the morning itself.
Remind your child that some questions will feel easy and some harder; that is normal in an adaptive test.
Use a simple plan: read carefully, choose, move on, reset.
If your child also has an interview or experience session, encourage polite, natural conversation rather than rehearsed answers.

The most reassuring message is this: the school is not expecting perfection. It is looking for a child who can engage sensibly with the assessment and show good potential.

After the exam: results, allocation and appeals

After the assessment stage, independent-school admissions usually move from test results to offers made by the school itself, rather than through the local-authority National Offer Day system used for state schools. For St Catherine’s, the school’s admissions information for the recent cycle shows a sequence of registration, testing, and interview or experience activity for external candidates.

We did not find a verified published date in the sources reviewed for when Year 7 decisions are released for 2028 entry, and we did not find a published appeals process equivalent to maintained-school admission appeals on the senior school page reviewed. If your daughter is not offered a place, the practical next step is to ask the school whether there is a waiting list and what the timeline is for movement.

Because independent schools can have their own offer and acceptance timetable, always read the current St Catherine’s admissions page carefully once the 2028 entry information is live. Keep copies of registration emails, assessment confirmations and any correspondence about interviews or offers.

What has changed recently

The clearest recent published point is that St Catherine’s senior school admissions page for the latest cycle states that 11+ candidates for September 2027 entry sat the ISEB Common Pre-Tests in October or November, with a school sitting offered on 18 November 2026 and all tests completed by 30 November 2026. The same page also shows that external candidates were invited to an Experience and Interview Day on 7 November 2026. We did not find any separately announced recent change to catchment, places or a new exam board beyond the school’s current published admissions arrangements.
