How to prepare for St Mary's School for Girls 11+

The exam at a glance

St Mary’s School for Girls is an independent school in Colchester with a Senior School at 91 Lexden Road, Colchester, Essex CO3 3RB. For Senior School entry, the school’s admissions information says that girls are invited to attend an assessment day and an interview as part of the entry process.

For 2028 entry, ElevenReady’s verified information is that the school uses its own assessment. The exact format, tested subjects, timing and delivery are not confirmed in our verified data. The school’s public admissions information fetched for this guide describes an assessment day, but it does not set out a detailed paper-by-paper breakdown, so parents should treat the school’s admissions page as the key source for any updates.

What the day looks like, based on the school’s admissions page, is likely to include:

an admissions visit or open event before application, if you wish
submission of an application form
an assessment day arranged by the school
an interview
a reference request from your child’s current school

Because this is an independent-school process rather than a local-authority 11+ round, it is sensible to expect a more school-led timetable and more direct communication with the admissions team than parents may be used to with grammar-school testing.

Registration and key dates

St Mary’s runs its own admissions process. The school’s admissions page asks families to complete an application form and return it to the school office or by email. The same page says a copy of your daughter’s birth certificate and her latest school report should be included, and that the school will then arrange an assessment and request a reference from the current school.

For 2028 entry, I could not verify a published set of Year 7-specific registration dates, deadline dates, test dates or results dates on the school’s public pages fetched for this guide. In other words, the school does not appear to publish a fixed 11+ timetable in the same way a grammar school would, at least on the pages reviewed.

That means the practical next steps for parents are:

check the school’s admissions page regularly for updated Senior School entry information
contact the admissions team early in Year 5 or at the start of Year 6 to ask when assessments for September 2028 entry will be scheduled
sign up for Free email alerts for this school's key dates

If the school later publishes specific dates, use those rather than relying on a typical independent-school pattern. For a fuller school summary page, see The St Mary's School for Girls 11+ guide (format, catchment, dates).

Who can apply: catchment and admissions

There is no catchment area in ElevenReady’s verified school data for St Mary’s School for Girls, which fits the usual pattern for an independent school. Admission is not governed by local-authority catchment maps in the way many state grammar schools are.

The school’s admissions page says that prospective pupils for the Senior School are considered through an application, an assessment, an interview and a reference from the current school. The school also says that offers are made by the Headmistress after the admissions process is complete.

I could not verify a published number of Year 7 places, a published oversubscription policy for external Year 7 entry, or any published pass mark or score threshold. If you need those details, check directly with the school because independent schools often discuss availability and suitability case by case rather than publishing a standardised 11+ cut-off.

In practical terms, parents should assume that:

there is no state-school-style catchment advantage to living nearby
the school will look at your child’s suitability for the school through its own admissions process
places may depend on availability in the year group as well as performance in assessment and interview

A month-by-month preparation plan

Because the exact paper format is not confirmed, the most sensible plan is a broad, balanced preparation programme that builds strong core skills first and only becomes more test-focused once the school gives clearer information. For a Year 5 child aiming for an autumn assessment in Year 6, this usually works well:

Month	What to do
January to March in Year 5	Keep preparation light: around 1 to 2 hours a week. Focus on secure reading comprehension, fluent arithmetic, careful written work and confident speaking. Read widely, revise times tables and number facts, and build the habit of checking work carefully.
April to May in Year 5	Increase to 2 hours a week if your child is coping well. Start short, varied tasks rather than long papers. Practise following written instructions, solving multi-step maths problems and explaining answers aloud.
June to July in Year 5	Move to 2 to 3 hours a week. Add occasional timed sections of 10 to 15 minutes, not full mock papers yet. This is a good stage to visit the school, ask admissions questions and watch for any published details about the assessment.
August before Year 6	Do little and often: about 2 to 3 hours a week split over several sessions. Revise core skills, read daily and keep confidence high. If the school has by then confirmed the format, begin tailoring practice more closely.
September in Year 6	Raise to 3 to 4 hours a week if needed, but avoid overload. Begin timed papers only if you know the school uses them or if your child needs practice with pace. Otherwise, use mixed short exercises plus interview-style conversation.
The final 2 to 3 weeks	Consolidate rather than cramming. Review mistakes, practise neat presentation, and do one or two realistic sessions each week. Make sure your child can speak naturally about school life, interests and why she wants to join St Mary’s.

If your child is bright but not used to formal preparation, consistency matters more than volume. A calm 20 to 30 minutes four times a week is usually better than one long weekend session.

Subject by subject: what to practise

Because the school’s public information reviewed for this guide does not confirm the exact tested subjects for Year 7 entry, the safest approach is to practise the areas most commonly looked at in independent-school senior entry: reading, writing, maths and interview confidence. If St Mary’s later publishes a more detailed assessment breakdown, use that as your guide.

English

Build strong reading comprehension first. Your child should be comfortable reading fiction and non-fiction, finding evidence, explaining word choices and summarising ideas clearly. Also practise accurate spelling, punctuation and grammar, because these often matter even when there is no separate SPaG paper.

For writing, work on planning quickly, writing in full sentences, organising paragraphs and checking carefully for errors. Independent schools often value clear expression and thoughtful ideas as much as speed.

Mathematics

Keep arithmetic fluent: the four operations, fractions, decimals, percentages, ratio basics, measure and problem solving. Many children lose marks not because the maths is beyond them but because they rush or misread what is being asked.

Practise short mixed sets and then review errors slowly. Ask your child to explain her method aloud. That helps build confidence for both written work and any interview conversation about problem solving.

Reasoning or broader cognitive skills

The exact format is not confirmed, so do not assume there will be a separate verbal or non-verbal reasoning paper. However, it is still useful to practise pattern spotting, precise vocabulary, logical thinking and following instructions carefully, because these underpin many selective assessments.

Keep this light unless the school later confirms a specific reasoning element.

Interview and school-readiness

The school’s admissions page specifically mentions an interview, so this is one part of preparation that parents can plan for with confidence. Help your child get used to speaking politely and naturally with an adult she does not know well.

Talk about books she has enjoyed and why
Ask what she likes at school and what she finds challenging
Discuss clubs, music, sport or hobbies
Practise listening to a question fully before answering
Encourage eye contact, but keep it natural

The aim is not rehearsed speeches. It is warm, thoughtful conversation.

Practice papers and mock exams

With a school-set assessment, practice papers are most useful when they strengthen the underlying skills rather than trying to mimic an unconfirmed format too exactly. Use them to build stamina, accuracy and confidence.

A sensible routine is:

start with untimed work to make sure methods are secure
move to short timed sections once your child is accurate
review every mistake carefully and sort errors into knowledge gaps, rushed mistakes and misunderstanding of instructions
repeat similar question types a week later to check that the learning has stuck

For school-specific resources, use:

If you use mock exams elsewhere, treat them as a way to practise focus and nerves, not as a prediction of whether your child will get a place. For this school especially, an interview, current-school reference and overall fit may matter alongside any written assessment.

On the day

Keep the morning simple. Aim for an ordinary breakfast, comfortable uniform or clothing if the school specifies it, and plenty of time to arrive without rushing. Last-minute cramming rarely helps.

Remind your child of just a few things:

read instructions slowly and twice if needed
if a question feels hard, stay calm and move on, then come back
show working clearly in maths
check punctuation, spelling and missing words in English tasks
in interview, listen fully and answer honestly

Children often worry that they must sound impressive in interview. In reality, schools are usually trying to get a sense of how teachable, thoughtful and ready for the school a child is. Warmth, manners and genuine conversation matter a great deal.

For parents, the most helpful tone is calm confidence: “Do your best, listen carefully, and let them see the real you.”

After the exam: results, allocation and appeals

Because this is an independent-school admissions process, the post-exam route is different from a state secondary allocation round. The school’s admissions page says that after assessment, interview and reference, offers are made by the Headmistress.

I could not verify a published date for when Year 7 decisions are normally released, nor any formal published appeals timetable equivalent to local-authority school appeals. If your child is not offered a place, the practical next step is to ask the school whether there is a waiting list, whether feedback can be provided, and whether a later application point is possible if circumstances change.

Parents applying to both independent and state schools should keep all separate deadlines in view. An independent-school offer does not replace the need to complete your local-authority secondary application if you also want state-school options.

What has changed recently

I did not find any clearly announced recent change, on the public pages reviewed, to St Mary’s Year 7 assessment board, test format, catchment arrangements or published admissions timetable in the last two years. If the school publishes a new admissions or assessment process for 2028 entry, parents should follow that updated guidance first.
