When Should You Start 11+ Preparation in Slough and Buckinghamshire?

The short answer: most families in Slough and Buckinghamshire start structured 11+ preparation in Year 4, roughly 12 to 18 months before the September Year 6 test date. Starting in Year 5 is still workable if your child already reads well and enjoys problem-solving. Waiting until Year 6 leaves little room to build exam technique alongside the normal school curriculum.

The 11+ Timeline, Month by Month

• Year 4 (autumn to summer): build core skills without pressure. Regular reading, times tables fluency, and light exposure to verbal and non-verbal reasoning puzzles.

• Year 5 (autumn to Easter): move to regular weekly practice. Introduce timed verbal reasoning and non-verbal reasoning papers alongside maths and English.

• Year 5 (summer term): first full mock papers under timed, exam-style conditions.

• Year 6 (September): the test itself. Both the Slough Consortium and Buckinghamshire sit their tests on a Saturday in September.

• Year 6 (October to March): results, grammar school offers, and appeals if needed.

Slough Consortium vs Buckinghamshire: What Differs

The Slough Consortium covers four grammar schools: Herschel Grammar School, Langley Grammar School, St Bernard's Catholic Grammar School, and Upton Court Grammar School. Sit the test once and the result is shared across all four. Buckinghamshire covers 13 grammar schools across the county, and again, one sitting counts for all of them.

Important update: Slough Consortium is changing test provider

On 13 July 2026, the Slough Consortium announced it has appointed Quest Assessments as its new test provider. This does not affect children sitting the test in September 2026, who will still take the GL Assessment papers. The change first applies to children who finished Year 4 in July 2026 and who will sit the 11+ in September 2027, for entry to secondary school in September 2028.

The subjects tested stay the same: English, Maths, Verbal Reasoning and Non-Verbal Reasoning, with age-standardised scoring and a qualifying score of 111. What changes is the format. GL Assessment papers run for roughly 60 to 65 minutes each; Quest Assessments papers run for around 50 minutes each, and most use an OMR (Optical Mark Recognition) answer sheet, where your child marks a line through a box rather than writing an answer. If your child is currently in Year 4 or below, factor practice with OMR-style answer sheets into your preparation from Year 5 onwards, since marking technique is a skill in itself.

Starting in Year 4 vs Year 5 vs Year 6

Starting point	Time to test	What it looks like
Year 4	12-18 months	Gradual introduction, no pressure, building reading and reasoning habits
Year 5	6-12 months	Regular weekly sessions, timed practice ramping up, first full mock papers by summer
Year 6 (early)	3-6 months	Intensive, focused exam technique. Workable, but little room for gaps in core skills

What a Realistic Weekly Commitment Looks Like

• Year 4: 30 to 45 minutes, once or twice a week. Mostly reading, puzzles and light reasoning games. No formal timed papers yet.

• Year 5: around 1 hour, once or twice a week, plus short homework tasks between sessions. Timed papers introduced gradually through the year.

• Year 6 run-up: 1 hour, twice a week where possible, with regular timed mock papers under exam conditions in the final months before the test.

FAQs

From what age can my child start 11+ preparation?

Students can begin as soon as they are ready, usually from Year 4, to build skills and confidence ahead of the exam.

Do I need to prepare differently for the Slough Consortium versus Buckinghamshire?

The core skills overlap heavily: both test English, Maths, Verbal Reasoning and Non-Verbal Reasoning. The differences are in format and paper structure, so once your child sits the test date is confirmed, it's worth practising past papers from the specific provider (GL Assessment or Quest Assessments) and, for Buckinghamshire, familiarising them with the two-paper split described above.

What if we're starting in Year 6?

It's still possible. Tell us the test date and we'll build a focused plan around it, prioritising exam technique and the areas that will move the score most in the time available.
