Slough Consortium of Grammar Schools 11 plus guide

Applying to a Slough grammar school for September 2028? This guide covers the Slough Consortium 11+, who sets it, the key dates, and how the four schools allocate their places.

The test provider has changed. The Slough Consortium 11+ is now set by Quest Assessments rather than GL Assessment. The shape of the test is broadly the same — two papers covering English, maths, verbal reasoning and non-verbal reasoning — so a child already preparing for the Slough 11+ is preparing for the right things.

The consortium hadn't published its exact registration and test dates when this page was last checked. We've shown the months it has confirmed and left the rest open rather than estimating from last year's timetable, because the test provider has changed and the old pattern may not hold. Always check with your target schools nearer the time.

What is the Slough Consortium 11 plus?

It is the shared academic entrance test for the four grammar schools above, set by Quest Assessments. The consortium's arrangements are set out on Quest's parent guidance page for the Slough Consortium 11+. Atom Home and Quest Assessments are both part of Atom Learning.

The test is sat in September of Year 6. Children born between 1 September 2016 and 31 August 2017 sit it in September 2027 for entry to Year 7 in September 2028.

Grammar schools use the 11 plus to select children working in the top ability range for their year group. Children in the top 25% are normally well-suited to a grammar school place.

What's in the Slough Consortium 11 plus?

Two papers, sat in a single session at one of the four Slough grammar schools, with a short supervised break between them. Each lasts about 50 minutes, plus time for instructions and some unmarked practice questions at the start.

It is a paper test. Your child marks their answers on a separate pre-printed answer sheet, drawing a horizontal line through the box next to their chosen answer. Each subject has its own answer sheet. Quest says the whole thing typically takes two to three hours including settling in.

No items found.

English

Reading comprehension — reading a passage and answering questions on it — alongside grammar, punctuation, spelling and vocabulary, all based on the Key Stage 2 national curriculum.

Maths

Maths questions cover the Key Stage 2 curriculum: number, measurement, geometry and statistics. Some of the harder questions ask your child to apply those skills to unfamiliar, multi-step problems.

Verbal reasoning

Verbal reasoning asks children to solve problems with written information — spotting relationships between words, working with letters and symbols, applying logic to text. It isn't taught at primary school, so the question types will be unfamiliar unless your child has seen them before.

Non-verbal reasoning

Non-verbal reasoning is visual problem-solving with shapes, diagrams and patterns: completing sequences, spotting what a set of shapes has in common, and using spatial awareness.

Free familiarisation materials

Quest publishes four free familiarisation booklets for the Slough Consortium test — English, maths, verbal reasoning and non-verbal reasoning — each with sample questions and a practice answer sheet, alongside guidance for children and parents, recommended reading lists for Years 3 to 6, and a vocabulary list. They are on Quest's Slough Consortium page.

Families eligible for Pupil Premium can request free access to Atom Home through the same page.

How is the Slough Consortium 11 plus scored?

Answer sheets are marked using Optical Mark Recognition (OMR). Scores are then age-standardised, so younger children in the year group aren't disadvantaged.

Results are sent to parents in mid-October 2027. If your child meets the qualifying standard for your target school, you then apply through your common application form.

What's the pass mark for the Slough Consortium 11 plus?

No qualifying score has been published for the new test.

The old figure does not automatically carry across. Under GL Assessment, a total standardised score of 111 — roughly the top 35% of the cohort — made a child eligible for a place at a Slough grammar school. A qualifying score belongs to the test that produced it, so if you find a Slough pass mark from an earlier year, treat it as background rather than a target. The consortium will publish a standard for the new test in its own time.

Meeting the qualifying score makes your child eligible. It doesn't guarantee a place — many Slough grammar schools are oversubscribed with children who meet it, and each then applies its own oversubscription criteria. Those are set out in our individual school guides:

How to apply to grammar schools in Slough

If you're considering a grammar school, it's worth speaking to your child's teacher first. Grammar schools select children working towards the top of their year group, and their teacher can tell you whether they think your child would keep up with the pace.

1. Register for the Slough Consortium 11 plus

To be considered at any of the four schools, register your child for the test.

  • Registration opens: May 2027 — the exact date isn't published
  • Registration closes: not yet published

Registration has previously run through the Slough Consortium of Grammar Schools' application portal. The consortium hasn't confirmed whether that stays the same for the new test, so check the schools' websites nearer the time.

2. Apply for school places

Results arrive in mid-October 2027, telling you whether your child met the qualifying standard at your target schools. Use them to decide which schools to name on your common application form, checking each school's admissions policy before you list it.

The form goes to your home local authority by Sunday 31 October 2027. That date falls on a Sunday, so it's worth submitting before the weekend.

3. National offer day

On Wednesday 1 March 2028 you'll find out which school your child has been allocated. They'll get a place at your highest preference for which they meet the criteria and where places are available.

If none of your preferred schools has a place, your child will be offered one elsewhere in your area. You can appeal to an independent panel; your local authority sends information about appealing alongside the offer.

How can I help my child prepare?

Stay on track with a clear plan

One of the hardest parts of 11+ preparation is knowing what to focus on, when, and how to make steady progress without it taking over family life. A clear plan helps your child build skills in the right order and avoid last-minute cramming.

Atom's exam plan makes this easier. Enter your child's target schools and exam dates, and we'll build a personalised weekly plan around the topics they'll meet. It adapts as they improve and keeps things manageable — little and often.

Practise working to time

Atom's 11+ practice papers are built to match the format, timing and question styles of real 11+ exams. They're unlimited, so your child can sit the same paper repeatedly and get new questions each time.

Photograph the completed answer sheets and upload them for instant marking, a standardised age score (SAS), and a clear view of which topics to work on next.

Encourage regular reading

Strong reading skills feed directly into both the English content and the verbal reasoning questions. Encourage your child to read every day, even for 10 to 15 minutes, with variety — fiction and non-fiction, different genres, a range of authors. Over time this broadens vocabulary, improves comprehension and inference, and builds confidence with unseen texts.

Explore Atom's free reading and writing starter kit for age-appropriate suggestions.

Celebrate progress, not just scores

What matters through 11+ preparation is knowing your child is moving in the right direction, not how they scored on one test. Atom's progress tracking shows how they're doing across topics and which way each one is heading, so you can keep encouragement specific and motivation steady.
