Slough and Berkshire 11 Plus: The Grammar Schools Guide, Including How Close You Need to Live

📖 11 min read 👪 For parents 📊 Fact-checked, Sep 2026 📅 Updated September 2026

Slough is one of the few places where a child can score comfortably above the qualifying mark and still not get a place. A four-mile line on a map is applied before exam rank. If you are weighing up a move, a rental, or simply whether to bother applying from further out, the detail below is the part that actually decides it.

Short answer: four grammar schools share the Slough Consortium 11+ (Herschel, Langley, St Bernard's Catholic and Upton Court), sat in September of Year 6. A standardised score of 111 or above makes a child eligible — but eligibility is not a place. At Herschel, children inside the four-mile catchment are ranked ahead of everyone else, and only the places left after that are filled purely on exam score. Reading School and Kendrick are in Berkshire but run separate arrangements.

Written through four expert lenses. This guide reflects four perspectives with 20+ years each: a former grammar school admissions lead and consortium examiner; a head of 11+ at a national tuition provider; an educational assessment specialist who has built reasoning tests and standardisation models at a major exam board; and an independent-school registrar. Every figure and claim below is checked against the primary source listed at the end — confirm current detail before relying on it.

The catchmentHerschel: four miles, straight line, front door to main entrance gate

Quick take:

111 makes your child eligible for consideration. It does not make them likely to get in.
Inside the four miles, you are ranked above every out-of-catchment child regardless of their score.
Outside it, you are competing for the places left over — on pure exam rank, so the score needed is much higher.

The four schools, and one test

The Slough Consortium of Grammar Schools comprises Herschel Grammar School, Langley Grammar School, St Bernard's Catholic Grammar School and Upton Court Grammar School. Your child sits one Consortium 11+ examination, set and administered by the Consortium using GL Assessment, and the resulting standardised score is used by all four. Registration runs through a portal reached from any of the consortium school websites, in a six-week window during May and June of Year 5.

For September 2027 entry, the examination is held in autumn 2026 (19 September 2026) for children born between 1 September 2015 and 31 August 2016.

What "qualifying" actually means here

Herschel's determined admissions arrangements state it plainly: "A standardised score of 111 or above in the entrance examination means that an applicant is eligible for consideration for admission to the School." The school notes that 111 puts a child in roughly the top 35% of the cohort sitting the examination.

The distinction that catches parents out: eligible is not the same as offered. In an oversubscribed year, a large number of children clear 111. What separates them afterwards is the oversubscription criteria below — and the first thing those criteria look at is not the score.

How close do you actually need to live?

This is the heart of it. Herschel's published oversubscription order for September 2027 entry runs:

Looked after and previously looked after children.
Pupils living within the school catchment area, defined as a home address within 4 miles of the school. Distance is measured in a straight line from the front door of the child's home address (including flats) to the main entrance gate of the school, using a Geographical Information System, with those closest receiving higher priority.
Up to a further 10 places for eligible applicants within 10 miles of the school who are eligible for the Pupil Premium at the closing date for the Common Application Form.
Children of permanent staff continuously employed by the school for at least 2 years.
The remaining places, up to the published admission number of 150, allocated to pupils in rank order of performance in the examination. Where multiple applicants achieve the same score, they are ranked by proximity, closest first.

The nuance worth understanding: Herschel is a hybrid, not a pure catchment school and not a pure super-selective. Criterion (ii) means a child inside four miles who scrapes 111 is ranked above a child outside four miles who scores 135. But criterion (v) means out-of-catchment children are genuinely admitted — on the places remaining, in strict rank order of score. Living outside the catchment is not a closed door. It just raises the score you need dramatically, and that bar moves every year with the cohort.

If two children live an equal distance away, the school uses random allocation supervised by someone independent of the school as the final tie-breaker.

Upton Court, and why the four schools are not interchangeable

The same 11+ score feeds all four schools, but each sets its own admissions arrangements, and they differ meaningfully in how much weight goes to distance versus rank. Upton Court, for example, is widely reported to allocate a substantial majority of its places on examination score rather than by a catchment boundary. Its arrangements also carry priorities for looked-after children, pupil premium places, staff children and feeder schools.

Check each school's own document, not a summary: arrangements are determined annually and differ school by school. Read the "determined admissions arrangements" PDF published on each school's own website for the year your child is applying — that document, not a league table or a tuition blog, is what the admissions panel actually applies.

Reading School and Kendrick are Berkshire, but they are not Slough

Parents searching "Berkshire 11+" often end up conflating two separate systems. Reading School and Kendrick School, both in Reading, run their own admissions arrangements. They are not part of the Slough Consortium, so a child wanting both would face separate registrations and separate tests. If those schools are on your list, treat them as a distinct process with distinct deadlines, and see our super-selective grammar schools guide for how schools of that type handle priority areas.

Best tips for parents, students and tutors

👪 For parents

Measure your actual distance before you do anything else. Four miles in a straight line is not four miles of driving. Use a straight-line distance tool from your front door to the school's main entrance gate — that is the measurement the school uses, via GIS, not a route-planner estimate.
If you are near the boundary, do not guess. Contact the school's admissions administrator and ask directly whether your address falls inside the catchment for the entry year you are applying for. Boundaries and measurement points are published; the school can confirm.
If you are outside four miles, plan for a much higher score, not a slightly higher one. Out-of-catchment children compete for leftover places in strict rank order. Build the preparation plan around a comfortable margin above 111, not a target of 111.
Don't treat the four schools as one application. Check each school's own determined arrangements — the balance between catchment and score differs, and that difference should shape which of the four you rank first on the Common Application Form.
Register in the May–June window and diarise it now. The registration window is roughly six weeks and closes well before the September test. Miss it and there is no route in that year.

🎓 For students

One test, four schools — so one strong performance counts four times. There is no second chance in a different paper, and no separate test for each school. Treat the September date as the single event it is.
Get comfortable with GL-style question formats specifically. The Consortium uses GL Assessment, so practising the GL layout, timing and answer-sheet style is directly relevant, not generic preparation.
Practise finishing sections, not just getting questions right. Standardised scoring rewards completed papers; questions left blank at the end are the most common avoidable loss of marks.
Sit at least two full papers under proper timed conditions before September. Doing one section at a time at the kitchen table does not rehearse the thing that actually goes wrong on the day, which is pacing.

📚 For tutors

Ask for the family's home postcode at the first session. A Slough student's realistic target score is a function of their address. A child at 1.5 miles and a child at 6 miles need genuinely different preparation plans, and setting the same target for both is doing one of them a disservice.
Build out-of-catchment plans around rank, not the pass mark. For a family outside four miles, the relevant question is not "will they hit 111" but "can they land in the top slice of the cohort". Set mock targets accordingly and be honest with parents early.
Know which of the four schools weights score most heavily. It is the single most useful piece of advice you can give an out-of-catchment family choosing preferences, and it changes the school-ranking conversation entirely.
Flag the registration window in your spring sessions. Tutors are often the only person in the loop who knows the calendar. A reminder in May costs nothing and has saved families an entire application cycle.

Frequently asked questions

What score do you need to pass the Slough 11 plus?

A standardised score of 111 or above makes a child eligible for consideration at Herschel Grammar School, which the school describes as roughly the top 35% of the cohort sitting the examination. Eligibility is not the same as an offer — where the school is oversubscribed, places are then allocated using the oversubscription criteria, which rank catchment children ahead of out-of-catchment children.

What is the catchment area for Herschel Grammar School?

Herschel defines its catchment as a home address within 4 miles of the school. Distance is measured in a straight line from the front door of the child's home address, including flats, to the school's main entrance gate, using a Geographical Information System. Those closest to the school receive higher priority.

Can my child get into a Slough grammar school if we live outside the catchment?

Yes, but the bar is higher. At Herschel, places go first to looked-after children, then catchment children, then up to 10 pupil premium places within 10 miles, then staff children. The remaining places, up to the admission number of 150, are awarded in strict rank order of examination performance. Out-of-catchment children compete for those remaining places on score alone.

When is the Slough Consortium 11+ test for 2027 entry?

The examination is held on 19 September 2026 for entry in September 2027, for children born between 1 September 2015 and 31 August 2016. Registration takes place through a portal linked from the consortium school websites during a six-week window in May and June 2026.

Are Reading School and Kendrick part of the Slough Consortium?

No. Reading School and Kendrick School run their own separate admissions arrangements and are not part of the Slough Consortium of Grammar Schools. Applying to them involves a separate registration and separate assessment from the Slough Consortium 11+.
