How to prepare for the St Mary's School Ascot 11+

The exam at a glance

For 2028 entry, St Mary’s School Ascot uses its own entrance assessment. For Year 7 entry, the assessment focuses on Maths and English only. Verbal Reasoning and Non-Verbal Reasoning are not part of the test, so preparation should go deeper into core literacy and numeracy rather than spreading across extra paper types.

The school’s admissions information says its main intake is at 11+, and that girls are assessed through the school’s own entrance examination, an interview and a report from their current school. The papers are paper-based.

One important point for families to note is that the school’s admissions wording is not fully consistent about when the assessment takes place. On the admissions page, one part says 11+ candidates sit the assessment in the Lent term of the year of entry, while another says girls applying at 11+ come to St Mary’s for a day in the December before the year of entry. Because of that, treat the exact assessment timing for 2028 entry as something to confirm directly with the admissions team.

In practical terms, parents should expect the assessment process to include:

an English paper, likely testing reading, comprehension and writing quality
a Maths paper, focusing on secure Key Stage 2 methods and problem solving
an interview
a school report from the child’s current school

That means preparation should not be only about doing papers. Strong written expression, careful reading, neat mathematical working and confident conversation all matter.

Registration and key dates

St Mary’s School Ascot handles its own admissions rather than using a local authority 11+ testing portal. The school’s admissions page says parents can register “as soon as you wish” and recommends registering at least two years before entry. For September 2028 entry, that means families should not wait for a narrow registration window in the way they might for a grammar school test.

The school provides an online registration form through its admissions process. Its fees page for 2026–27 lists a registration fee of £360 and an anti-money laundering check fee of £132. Families should expect the admissions office to explain exactly what documents are needed when they register, especially for identity and address checks.

For key timings, only a few points are clearly published:

Registration: open-ended; the school says families may register as soon as they wish.
Recommended timing: at least two years before entry.
Assessment timing: the admissions page gives conflicting information, referring both to the Lent term of the year of entry and to a day in December before the year of entry.
Results: normally notified within three weeks of sitting the examinations.
Open mornings: usually held four times a year, in March, May, September and November.

Because the page does not publish a single confirmed deadline or a single confirmed exam date for 2028 entry, it is best to check the school’s admissions page regularly and join alerts. You can also use Free email alerts for this school's key dates.

Who can apply: catchment and admissions

St Mary’s School Ascot is an independent girls’ school, so there is no state-school catchment system in the grammar-school sense. Instead, admission is governed by the school’s own criteria and assessment process.

The school says its main intake is at 11+, with about 40 pupils admitted to Year 7 each year. It also states that girls are selected through the entrance assessment, interview and a report from their current school.

On priority, the school says it gives preference to girls who are Roman Catholic. It also says that non-Catholic families are asked to contact the Admissions Office. That does not mean non-Catholic applicants cannot apply, but it does mean families should have an early conversation with the school about suitability and the admissions route.

Because this is an independent school, competition is not expressed through a published pass mark or local authority cut-off score. The school does not publish a standardised qualifying score for Year 7 entry on its admissions information, so parents should be cautious about any unofficial claims online.

If you are considering an application, the sensible first steps are:

register interest early
attend an open morning if possible
ask admissions to explain the likely timeline for your daughter’s year group
check how the interview and school report are used alongside the written papers

A month-by-month preparation plan

Because St Mary’s tests only English and Maths, a calm, steady plan works well. For most Year 5 pupils, 2 to 3 hours a week at the start is plenty, rising gradually later on. The aim is not to race ahead to secondary content, but to become very secure with primary-school skills and thoughtful written work.

12 months before the exam

Start lightly. Build habits in reading, spelling, vocabulary and arithmetic accuracy. Read daily, discuss books, and make sure number facts are fluent. At this stage, one short English task and one short Maths task each week is enough.

11 months before the exam

Check the basics. In Maths, work on the four operations, fractions, decimals, percentages and multi-step word problems. In English, focus on comprehension using short passages and on writing in full, well-punctuated sentences.

10 months before the exam

Increase to around 2 to 3 hours weekly. Begin more deliberate practice: one comprehension, one writing task and one Maths problem-solving session each week. Keep sessions short enough that concentration stays strong.

9 months before the exam

Start identifying patterns in errors. Does your child rush? Misread questions? Avoid showing working? Forget punctuation when ideas become more ambitious? Fixing these habits early is more useful than piling on extra worksheets.

8 months before the exam

Introduce occasional mixed practice. For Maths, combine arithmetic with reasoning and word problems. For English, mix retrieval questions, inference, vocabulary-in-context and one longer writing piece every fortnight.

7 months before the exam

Raise stamina gently. Try a slightly longer comprehension or a longer Maths paper section, but still untimed or loosely timed. This is also a good point to ask whether your child writes legibly and organises answers clearly enough for a paper-based exam.

6 months before the exam

Move towards exam-style work. Increase to around 3 to 4 hours a week if your child is coping happily. Begin light timing on individual sections rather than full papers. Review every mistake carefully together.

5 months before the exam

Start full-topic revision lists. In Maths, note any weak areas such as fractions, ratio-style problems, measures or interpretation of worded questions. In English, note whether the bigger issue is comprehension, planning, vocabulary or technical accuracy.

4 months before the exam

Begin occasional timed papers. For most children, this is the right point to start, rather than much earlier. One timed task in English and one in Maths every week or two is enough at first. Between papers, return to teaching and practice, not just testing.

3 months before the exam

Work on consistency. Children often know the content by now, but marks are lost through avoidable slips. Teach checking routines: re-read the question, underline key information, estimate before calculating, and leave time to review.

2 months before the exam

Use a few realistic paper-based practice runs at a desk, with a watch and planned breaks. Keep the tone calm. The goal is familiarity, not pressure. If interview preparation is needed, practise speaking clearly about books, hobbies, school life and interests.

1 month before the exam

Do not overdo it. Keep up one or two quality papers a week, plus targeted correction. Prioritise sleep, routine and confidence. Children improve most at this stage from tidy execution and calm focus, not from cramming new material.

Final two weeks

Scale back. Focus on accuracy, reading carefully and writing neatly. Use short refreshers rather than long sessions. If your child is tired, stop. A rested child usually performs better than an over-prepared one.

Subject by subject: what to practise

English

As St Mary’s sets its own paper, the exact question mix is not publicly standardised. In practice, parents should prepare for the core independent-school English skills that schools commonly look for at 11+: reading comprehension, vocabulary understanding and extended writing.

For comprehension, practise:

finding explicit information accurately
explaining word meanings in context
making inferences from clues in the passage
commenting on tone, character or atmosphere
answering in full sentences where appropriate

For writing, practise:

planning before starting
clear paragraphing
sentence control and punctuation
varied but accurate vocabulary
staying relevant to the task

A good routine is one comprehension and one writing task each week, with proper marking and redrafting. Redrafting is especially useful for independent-school English because it teaches children to notice what makes writing stronger.

Maths

For Maths, expect a paper that rewards both secure methods and careful reasoning. Because there are only two tested subjects, weak arithmetic can show up quickly, so fluency matters.

Practise these areas regularly:

place value and the four operations
fractions, decimals and percentages
ratio-style thinking at an age-appropriate level
measures, time and money
shape, perimeter, area and basic geometry
multi-step word problems
interpreting what the question is really asking

Children should show clear working, even when they can do some steps mentally. In paper-based exams, organised working can prevent errors and makes checking easier. Short daily arithmetic plus one or two longer reasoning sessions each week is usually more effective than long, infrequent maths practice.

Practice papers and mock exams

Practice papers are most useful when they are used as a diagnostic tool, not simply as a score generator. For this school, start with untimed or loosely timed work, then add timed papers later once the underlying skills are secure.

A sensible sequence is:

learn or revise the topic
practise a small set of questions
review every error carefully
redo similar questions a few days later
only then move to a fuller timed paper

After each paper, look at three things:

knowledge gaps — what your child did not know
method gaps — where they knew the topic but used a weak approach
exam gaps — rushing, misreading, untidy layout or poor time use

For school-specific practice, use Free St Mary's School Ascot practice papers (one per tested subject, with answers). These are a good way to build familiarity with the level and style expected.

You may also find these useful alongside your planning:

If you use mock exams, treat them as practice in routine and resilience rather than as a prediction. Independent-school selection includes more than one element, so one mock score should never define your child’s chances.

On the day

Keep the morning simple. Aim for a calm breakfast, comfortable uniform or clothes if specified by the school, and plenty of time for the journey. For a paper-based exam, check the practical details the night before: pencils, pens, rubber, ruler and anything the school has asked candidates to bring.

Children usually do best when the message is steady and reassuring:

read each question carefully
start neatly and keep going steadily
show working in Maths
if stuck, move on and come back
check the paper if there is time

If there is an interview as part of the day, remind your daughter that she does not need rehearsed speeches. Good eye contact, polite conversation and thoughtful answers matter more than trying to sound overly polished.

Parents can help most by keeping the tone ordinary. Avoid last-minute testing in the car or a big post-exam debrief the moment your child comes out. Food, water, rest and a normal afternoon are often the best next steps.

After the exam: results, allocation and appeals

St Mary’s says that results are normally notified within three weeks of sitting the examinations. Because this is an independent school, the process is different from state secondary allocation day. Families are usually dealing directly with the school over offers and next steps rather than through the local authority’s March allocation system.

If your daughter is successful, the school will explain how to accept the place and any deposit or acceptance stage. For 2026–27, the school’s fees page lists an acceptance fee of £2,400. Families should always check the latest fees page for the year they are applying, as charges can change.

If your daughter is not offered a place, ask politely whether there is a waiting list and whether any further feedback can be shared. Independent schools do not follow the same statutory admissions appeal system as state schools, so the right next step is to speak directly to the admissions office about review, waiting-list movement or alternative entry points if relevant.

It is also worth remembering that the school looks at more than one part of the application: written assessment, interview and school report. That broader view can matter both in offers and in any follow-up conversation.

What has changed recently

In the sources reviewed for this guide, we did not find a clearly announced recent change to the Year 7 entrance test format away from the school’s own assessment in English and Maths. The main point parents should note is not a confirmed change, but a timing inconsistency on the admissions page: one part refers to assessment in the Lent term of the year of entry, while another refers to an 11+ assessment day in the December before the year of entry. That is something to confirm directly with the school for 2028 entry.

The fees page does, however, publish the current fee schedule for 2026–27, including registration, checking and acceptance fees, which families may wish to monitor for future updates.
