How to prepare for Sir Henry Floyd Grammar School (11+ guide)

School-specific 11+ preparation for Sir Henry Floyd Grammar School in Aylesbury: the admissions test it uses, the registration timeline, and a free practice plan.

Families targeting Sir Henry Floyd Grammar School ask the same first question: what exactly should we practise? The honest answer is that good preparation fits the way this school selects. Sir Henry Floyd chooses its intake through the Buckinghamshire Secondary Transfer Test, sat county-wide in mid-September of Year 6, so your practice plan should mirror that test's subjects, its timing and its qualifying threshold rather than a generic 11+ routine. This guide sets out who the school is, how the Bucks test works, exactly what to drill, and a calm, unhurried timeline to get there.

About Sir Henry Floyd Grammar School

Sir Henry Floyd is Aylesbury's mixed grammar, smaller and more recent than the town's two long-established selective schools. Founded in 1959, it sits within Buckinghamshire's network of 13 state grammars, all of which admit pupils through the same county entrance test. That shared arrangement is genuinely helpful for parents: a child preparing for Sir Henry Floyd is preparing for exactly the same paper as one aiming at any other Bucks grammar, so a single, well-judged plan covers every preference you might list on your application. Being co-educational, the school draws boys and girls from Aylesbury and its surrounding villages, and as a foundation grammar it manages its own admissions within the county framework.

How selection works at Sir Henry Floyd Grammar School

Sir Henry Floyd does not set its own paper. Instead it uses the county-wide Buckinghamshire Secondary Transfer Test, administered on a single test day in mid-September of Year 6, before secondary applications are finalised. The test is delivered by GL Assessment in two papers: Paper 1 covers English and Verbal Reasoning, and Paper 2 covers Maths, Non-Verbal Reasoning and Spatial Reasoning. Papers are multiple-choice, tightly timed at roughly a minute a question, and completed with no calculator, with answers marked on a separate sheet. Crucially, results are age-standardised so that summer-born children are not disadvantaged simply for being younger than their autumn-born classmates: the raw score is adjusted for the child's exact age in years and months, so two children who get the same number of questions right can end up with different standardised scores depending on their birth month.

The qualifying score for a Buckinghamshire grammar place is 121 on the standardised scale, where 100 is the county average. Reaching or exceeding 121 means a child has "qualified" for grammar admission, but qualifying is not the same as securing a place: offers still depend on the school's published oversubscription criteria, such as catchment area, sibling links and any priority categories. If a child narrowly misses, Buckinghamshire operates a selection review (appeal) route where parents can submit further evidence for a panel to consider. Because Sir Henry Floyd shares this test with every other Bucks grammar, you can hold it as a genuine preference alongside the two larger Aylesbury schools without changing a thing about how your child prepares. The subject content of the test has stayed stable across recent years, which means practice done well in Year 5 carries directly through to the September sitting.

What to practise for this test

Because the Bucks test rewards broad, transferable skill rather than memorised tricks, spread practice across all four assessed areas and mix them within a single session so your child learns to switch quickly between question styles.

Start with a first timed mock paper to expose the weakest area, then target it with worksheets before returning to full papers again. The aim is not to grind through every sheet on the site but to find the two or three question types that consistently cost marks and turn them into strengths.

A realistic preparation timeline

The best Bucks preparation is slow and steady rather than an intense final sprint. Younger children benefit far more from a strong foundation than from early exam pressure, so build gradually.

Keep the intensity honest to your own child. Some are ready for full timed papers by the summer of Year 5; others need the reasoning types introduced more gently. What matters is that by the time the September test arrives, sitting a paper against the clock feels familiar rather than frightening.

On the day and after

By test day the goal is composure, not cramming. A child who has sat several timed mocks at the kitchen table treats the real exam hall as simply the next one in the series. Practical steps help most: a good night's sleep, a proper breakfast, arriving with time to spare, and a clear reminder to move on from any hard question rather than lose two minutes on it. On a multiple-choice paper, giving a sensible answer to every question is always worth it, since there is no penalty for a wrong guess. Afterwards, resist post-mortems and let your child switch off; results and any selection-review deadlines will follow the county timetable, which you can confirm on the school's website and through Buckinghamshire admissions.
