Boston Grammar School 11+ 2026: Admissions, Test Dates & Preparation

Boston Grammar School is a selective grammar school for boys in Boston, Lincolnshire, admitting 120 boys into Year 7 each September on the strength of the Lincolnshire Consortium 11+ test. For September 2027 entry, boys register between 7 January and 31 March 2026, sit two GL Assessment reasoning papers in September 2026, and need a combined standardised score of at least 220 to qualify — though with roughly 2.2 qualifying candidates for every place, reaching 220 is only the first hurdle. This page sets out the exact test format, the 2026 dates, the oversubscription rules, and how Leading Tuition prepares boys for Boston Grammar's specific requirements. For the full history, Sixth Form entry detail and a longer walkthrough of the admissions process, see our complete Boston Grammar School 11+ guide.

Boston Grammar School: Key Facts for 2027 Entry

What Test Do Boys Sit for Boston Grammar School 11+?

Boston Grammar School is a full member of the Lincolnshire Consortium of Grammar Schools, which shares a single 11+ test set and standardised by GL Assessment across the county's selective schools. Families moving from other regions are often caught out by this: there is no separate Maths paper and no English comprehension or creative writing component. The whole assessment rests on two reasoning papers.

Verbal Reasoning tests a boy's ability to work with word patterns, codes, sequences and logical relationships through question types including analogies, letter and number codes, hidden words, compound words, and synonym and antonym matching. For the 2026 cycle, this paper is scheduled for 11–12 September 2026.

Non-Verbal Reasoning with spatial awareness tests the ability to spot rules and relationships in abstract shapes — series, matrices, analogies and figure classification — extended into three dimensions through cube folding, block counting, shape rotation, nets and fold-and-punch problems. This paper is scheduled for 18–19 September 2026.

Both raw scores are age-standardised before being added together, adjusting for a boy's exact date of birth so a summer-born candidate is not disadvantaged against an autumn-born classmate. The combined qualifying threshold of 220 out of a maximum 282 identifies roughly the most able quarter of pupils tested across Lincolnshire's selective intake. Reaching 220 is necessary but not sufficient: it is Boston Grammar's own oversubscription criteria, set out below, that decide who actually receives one of the 120 places once demand exceeds supply — which at Boston Grammar it typically does, at a ratio of around 2.2 qualifying candidates per place.

What Are the Key Dates for 2027 Entry?

Note that sitting the 11+ test is a separate step from applying to the school itself. As the Lincolnshire Consortium makes clear, a child taking the test is not automatically an applicant — families must still submit a Common Application Form (CAF) to their home local authority by 31 October 2026, ranking Boston Grammar among their preferred schools. Missing either step, the test registration or the CAF, can cost a place regardless of the score achieved.

How Are Places Allocated When Boston Grammar Is Oversubscribed?

Boston Grammar School has no catchment area or priority zone. Any boy who registers and reaches the 220 qualifying score may apply, regardless of where in Lincolnshire — or beyond — the family lives. When qualifying applicants exceed the 120 places, the school works through a fixed order of oversubscription criteria:

• 1. Looked-after and previously looked-after children.
• 2. Pupil Premium registration — children who have been eligible for Free School Meals at any point in the last six years.
• 3. Siblings of pupils already attending the school.
• 4. Straight-line distance from home to school, calculated by Lincolnshire County Council's admissions software, applied to all remaining qualifying boys.

If distance cannot separate the final available places, an independent lottery decides the outcome. Because distance is used only as a tie-break rather than a catchment requirement, families well outside Boston itself do apply successfully — but they should understand that a strong score alone will not override the sibling or Pupil Premium categories ahead of them in the queue.

What Ofsted Rating and Results Does Boston Grammar School Have?

Boston Grammar School holds a Good Ofsted rating, from an inspection carried out on 5 October 2021. Academically, the school's most recently published figures show an Attainment 8 score of 53.1 and 79.2% of pupils achieving grade 5 or above in English and maths GCSE. At A-Level, 15.1% of entries achieved AAB or better, and around 55% of leavers progress into higher education. The school is led by headteacher Mr John McHenry.

Why Is Boston Grammar School So Sought-After?

Boston Grammar School's history stretches back further than almost any school in Lincolnshire: it traces its foundation to a royal charter granted by Philip and Mary in the 1560s, with the oldest surviving buildings on its South End site dating to 1567. The school converted to academy status on 1 January 2013 and organises pupils into four houses — Laughton, Muston, Gannock and Parry — each named after a historical figure connected to the school. Its Latin motto, Floreat Bostona ("May Boston Flourish"), is also the title of the school song.

One fact rarely mentioned in 11+ admissions guides: the school's South End site is understood to have provided the architectural and organisational model for Boston Latin School in Massachusetts, founded in 1635 and recognised as the first public school established in what became the United States. The Lincolnshire town of Boston gave its name to the Massachusetts city, and its grammar school's influence appears to have travelled with it — a piece of transatlantic heritage that adds real texture for families researching the school beyond the raw admissions numbers.

Notable former pupils include Professor Sir Jonathan Van-Tam, the former Deputy Chief Medical Officer for England who became a familiar public figure during the COVID-19 pandemic, and Barry Spikings, the Oscar-winning film producer behind The Deer Hunter. Boys have been educated at Boston Grammar continuously since Year 7 to Year 11 has been boys-only throughout its history, while its Sixth Form — with 70 places — is co-educational, admitting girls from Year 12 alongside boys progressing from Year 11.

How Should My Son Prepare for the Boston Grammar School 11+?

Preparation for Boston Grammar School should concentrate entirely on the two components of the Lincolnshire test: Verbal Reasoning and Non-Verbal Reasoning with spatial awareness. Neither is part of the national curriculum, so boys need structured, progressive practice well before the September 2026 test dates — and because Lincolnshire drops the Maths and English papers that many other counties include, time spent on those subjects for a different 11+ format is time not spent on the skills Boston Grammar actually tests.

Leading Tuition's specialist 11+ tuition begins with a diagnostic assessment across both paper types to establish exactly where your son stands relative to the 220 threshold. From there we build a personalised programme: vocabulary and pattern-recognition work for Verbal Reasoning, spatial and figure-based training for Non-Verbal Reasoning, and progressively timed practice papers as the September dates approach, so your son arrives with both the accuracy and the exam stamina Boston Grammar's competitive field demands. We also cover the practical side — registration, the CAF deadline, and how the oversubscription criteria affect your family's position — so nothing procedural costs a place that the test itself has earned.

For families weighing Boston Grammar alongside other Lincolnshire Consortium schools, our tutors prepare boys for the shared GL Assessment format, which transfers directly across every school in the consortium.
