Lincolnshire Grammar Schools 2026: Complete Parent Guide

Lincolnshire has one of the largest concentrations of selective grammar schools in England, with 15 schools in the Lincolnshire Consortium of Grammar Schools plus the independently administered Caistor Grammar School. Whether your child is aiming for a school in Lincoln, Grantham, Spalding, Boston, Louth or Gainsborough, this guide covers everything you need to know about the 2026 admissions cycle: which schools use the consortium test, how the GL Assessment works, the qualifying score, 2026 key dates, and how to build an effective preparation strategy.

Lincolnshire’s grammar system is often less well-known than those in Kent, Buckinghamshire or Trafford, but it is equally rigorous and well-established. The county’s selective schools have deep roots, many with histories stretching back to the Tudor period, and they consistently produce strong GCSE and A-Level results. Understanding how the system works — and how to navigate it effectively — is the first step towards giving your child the best possible chance.

What Makes Lincolnshire’s Grammar School System Unique?

Lincolnshire’s approach to selective secondary education differs in several important ways from other areas of England. Rather than each school setting its own entrance exam, 15 of the 16 selective schools in the county pool their admissions testing through the Lincolnshire Consortium of Grammar Schools. This consortium model means that:

Children sit a single GL Assessment test, and that result is valid for all 15 consortium schools simultaneously. There is no need to register separately for each school or sit multiple exams across different weekends. Families simply register once through any participating school’s website, sit the two consortium papers in September, and then apply via the Common Application Form to whichever qualifying schools they wish to attend.

The only exception is Caistor Grammar School, which sits outside the consortium and administers its own verbal reasoning tests on separate dates in late September 2026. If Caistor is on your list, you must register directly with the school before its own deadline of 14th August 2026, independently of any consortium registration.

The consortium also offers a noteworthy logistical advantage: the two papers are sat on separate Saturday mornings, one week apart. This gives children the opportunity to approach each paper fresh, rather than sitting both components in a single extended session as happens in some other areas.

The 15 Lincolnshire Consortium Grammar Schools

The Lincolnshire Consortium currently comprises 15 selective schools spread across the county. They divide into co-educational (mixed), boys’ and girls’ schools as follows.

Co-educational grammar schools: Bourne Grammar School (Bourne); King Edward VI Grammar School, Louth; King Edward VI Academy, Spilsby; Queen Elizabeth’s Grammar School, Alford; Queen Elizabeth’s Grammar School, Horncastle; Queen Elizabeth’s High School, Gainsborough; and Skegness Grammar School.

Boys’ grammar schools: Boston Grammar School; Carre’s Grammar School, Sleaford; Spalding Grammar School; and The King’s School, Grantham.

Girls’ grammar schools: Boston High School for Girls; Kesteven and Grantham Girls’ School; Kesteven and Sleaford High School; and Spalding High School.

All 15 schools use the same entrance test administered by GL Assessment, with the same qualifying threshold of 220 on the combined standardised score. Each school’s individual admissions policy then determines how places are allocated among qualifying candidates when a school is oversubscribed — typically prioritising looked-after children, then catchment applicants, then siblings, then distance.

Caistor Grammar School: The Independent Exception

Caistor Grammar School, located at Church Street in Caistor, North Lincolnshire (LN7 6QJ), operates independently of the consortium with its own admissions timetable and test format. Like the consortium schools, Caistor uses a qualifying threshold of 220 on a combined standardised score, but the tests themselves are administered directly by the school on separate dates.

For September 2027 entry, Caistor’s registration deadline is 14th August 2026 — notably later than the consortium’s March deadline, but still before the autumn term. The two papers are sat on 19th September (Standard Verbal Reasoning) and 26th September 2026 (Multiple Choice Verbal Reasoning). Results are communicated to parents by email on or before 13th October 2026.

Caistor is an Ofsted Outstanding co-educational school with around 680 pupils across Years 7 to 13, and a sixth form with a reputation for strong A-Level results and university progression. Its location in the Lincolnshire Wolds makes it particularly popular with families in North and North East Lincolnshire. Children living within 6.5 miles of the school “as the crow flies” are considered in-catchment and receive priority in oversubscription.

How the GL Assessment Works in Lincolnshire

The Lincolnshire Consortium 11+ is set by GL Assessment, one of the most widely used assessment providers in the UK grammar school system. GL Assessment designs tests that measure academic potential and reasoning ability rather than curriculum knowledge, which is why the Lincolnshire test focuses entirely on verbal reasoning and non-verbal and spatial reasoning, with no mathematics paper.

The test consists of two separate papers:

Paper 1 — Verbal Reasoning: This paper lasts 50 minutes and contains 80 questions across approximately 15 sections. Each section groups 5–6 questions of the same type. Topics include vocabulary (synonyms, antonyms, odd ones out), word-building (anagrams, missing letters, jumbled sentences), code-breaking, number logic with letters and sequences. The paper is multiple-choice, with a separate pre-printed answer sheet. A short unmarked practice section appears at the start.

Paper 2 — Non-Verbal and Spatial Reasoning: This paper contains 70 questions split into five timed sections, each lasting approximately 7 minutes. Three sections assess non-verbal reasoning (relationships between abstract shapes, sequences, matrices, odd-one-outs, codes) and two assess spatial reasoning (identifying parts within shapes, rotations, reflections, fold-and-cut problems). Children work through each section when instructed by the invigilator and cannot move ahead.

Both papers use Optical Mark Recognition (OMR) marking, where children mark answers on a separate answer sheet. Scores are then age-standardised so that summer-born children (born in May–August) are not penalised relative to those born in September–December. The qualifying threshold is a combined standardised total of 220 or more across both papers. For a deeper dive into the test format, see our Lincolnshire 11+ Format Guide 2026.

2026 Lincolnshire 11+ Key Dates and Registration Deadlines

The table below summarises the key dates for the Lincolnshire Consortium and for Caistor Grammar School separately. Note that the consortium registration window closed in March 2026 — families who missed it cannot enter the consortium test. Caistor’s later August deadline remains open.

Milestone	Consortium (15 schools)	Caistor Grammar
Registration opens	January 2026	March 2026
Registration closes	31 March 2026	14 August 2026
Paper 1 (VR)	11 or 12 September 2026	19 September 2026
Paper 2 (NVR/Spatial)	18 or 19 September 2026	26 September 2026
Results	9 October 2026	13 October 2026
CAF deadline	31 October 2026	31 October 2026
National Offer Day	1 March 2027	1 March 2027

The familiarisation session for the consortium test is scheduled for Saturday 5th September 2026 at Bourne Grammar School, giving children the opportunity to experience the format in test conditions before the real papers. Some children may complete this at their primary school instead.

The Qualifying Score: What Does 220 Mean?

The qualifying threshold for all Lincolnshire grammar schools — both consortium and Caistor — is a combined standardised score of 220 or more across the two papers. This threshold is designed to identify children performing within the top 25% of the academic ability range nationally.

It is important to understand what the qualifying score means in practice. Each paper generates an age-standardised score, meaning the raw number of correct answers is adjusted to account for your child’s exact age at the time of the test. A child born in July will have their score “boosted” relative to a child born in the previous September, because younger children are expected to answer fewer questions correctly for their stage of development. The two standardised scores are then added together, and children who reach 220 or more are deemed to have met the qualifying standard.

Achieving 220 is a necessary condition for a grammar school place, but it is not sufficient on its own if a school is oversubscribed. At popular schools — particularly those in Lincoln, Grantham and Spalding — the majority of applicants who receive offers will have scored comfortably above 220. The most competitive schools tend to see qualifying candidates with combined scores in the 230–250 range securing places, while lower-scoring qualifiers may only be offered places at less-oversubscribed schools. Preparation should therefore aim not merely to clear 220, but to score as highly as possible above that threshold.

Lincolnshire County Council Admissions Process

Although individual grammar schools administer the 11+ test, secondary school places in Lincolnshire are coordinated by Lincolnshire County Council. The admissions process works in two stages: first, the 11+ test (in September); second, the Common Application Form (CAF) submitted by the 31st October 2026 deadline.

After test results are issued in early October 2026, families whose children meet the qualifying standard can list grammar schools on the CAF. The CAF is submitted to your home local authority (even if you are applying to schools in a different authority area). If you live in Lincolnshire, you submit via Lincolnshire County Council’s online portal. If you live in North East Lincolnshire (for Caistor), North Lincolnshire or another area, you submit via that authority’s system.

You can list up to six schools on the CAF in preference order. Listing a grammar school as your first preference does not reduce your child’s chances of being offered a place there, and listing it lower than another school does not increase your chances of getting into the higher preference. Preferences are considered simultaneously, not sequentially — so order your schools honestly by genuine preference.

National Offer Day is 1st March 2027, when Lincolnshire County Council and other local authorities simultaneously notify families of offers. If your child is not offered their preferred grammar school on offer day, you can join the school’s waiting list and appeal the decision — both routes are worth pursuing in parallel.

Oversubscription Criteria at Lincolnshire Grammar Schools

When a grammar school receives more qualifying applications than it has places, the school allocates places using its oversubscription criteria. While criteria vary slightly between schools, the typical priority order used by Lincolnshire consortium schools is:

First priority goes to looked-after children and previously looked-after children who qualify. Second priority is typically given to catchment children — those living within the school’s defined catchment area. Third priority is siblings of children already attending the school. Fourth priority is often children of staff (at some schools). Beyond these categories, remaining places are allocated by straight-line distance from home to school, with those living closer receiving priority.

Some schools also include specific provisions for children in receipt of the Pupil Premium or for children with siblings in the sixth form only — it is always worth checking each school’s individual admissions policy carefully rather than relying on a generic account. Policies are published on each school’s website and on the Lincolnshire County Council website.

Catchment areas in Lincolnshire can be both generous and nuanced. Rural grammar schools like De Aston (Market Rasen) and the schools in Spilsby, Alford and Horncastle draw from wide geographic areas, with many families travelling significant distances. Urban schools in Lincoln and Grantham tend to have tighter catchment boundaries and be more heavily oversubscribed. Checking whether your home address falls within catchment is a critical early step in the application process.

How to Prepare for the Lincolnshire 11+

Effective preparation for the Lincolnshire GL Assessment requires consistent, structured practice over a period of several months — ideally beginning in Year 5 or early Year 6. Because verbal reasoning and non-verbal and spatial reasoning are not subjects taught on the national curriculum, many children encounter these question types for the first time in preparation materials. Early exposure gives children the time to become genuinely confident with all the question types, rather than merely familiar with them.

Verbal Reasoning preparation should focus on building vocabulary (reading widely is the single most effective activity for long-term VR development), practising the full range of GL Assessment question types (codes, sequences, synonyms, antonyms, analogies, missing letters), and developing speed under timed conditions. Children sitting the consortium test have 50 minutes for 80 questions — approximately 37 seconds per question — so pacing is a genuine challenge that needs deliberate practice.

Non-verbal and spatial reasoning preparation requires a different approach. NVR tests the ability to identify patterns, relationships and rules in abstract shapes. Spatial reasoning requires the ability to mentally rotate, fold, reflect and manipulate two-dimensional images. Children who struggle with these tasks initially often improve dramatically with targeted practice, as the question types are highly learnable once their logic is understood. Timed section practice is especially important for the NVR/spatial paper, which is divided into five sections each with a strict 7-minute limit.

One-to-one tuition is particularly effective because it allows a tutor to identify a child’s specific weaknesses — whether in particular VR question types, NVR topics or test-taking strategy — and to direct preparation accordingly. Group tuition can help with familiarity and motivation, but personalised identification of gaps and targeted remediation is harder to achieve. At Leading Tuition, our specialist 11+ tutors are experienced with the GL Assessment format and work with children across Lincolnshire and nationally via online tuition.

Choosing the Right Lincolnshire Grammar School

With 15 consortium schools and Caistor offering a 16th option, families in Lincolnshire have more grammar school choices than in almost any other part of England. The challenge is identifying which schools are realistic options given your child’s likely score, your home address relative to catchment boundaries, and your family’s genuine preferences for school ethos, size and specialism.

It is generally advisable to apply to at least two or three grammar schools on the CAF to give your child the best chance of a grammar school place. Including schools where your address gives catchment priority alongside your first-choice school provides insurance. If your child scores in the 220–225 range, schools in smaller towns with less competition (such as Alford, Horncastle, Spilsby or Skegness) may be more accessible than those in Lincoln or Grantham, where competition is typically stiffer.

Gender-specific schools are a significant feature of the Lincolnshire system. Parents of girls considering Grantham or Spalding will be choosing between boys’ and girls’ schools in those towns, and their children’s preferences should be central to any decision. Similarly, families in Boston will be choosing between Boston Grammar (boys) and Boston High School for Girls, while Sleaford has both Carre’s (boys) and Kesteven and Sleaford High (girls). For most co-educational options, Bourne, Louth, Spilsby, Alford, Horncastle, Gainsborough and Skegness offer mixed-gender selective education.

Practical Next Steps for Families

If the consortium registration deadline of 31st March 2026 has passed and you did not register your child, the consortium test is no longer available for this cycle. However, Caistor Grammar School’s own registration remains open until 14th August 2026, providing a further selective option for this autumn.

For families with children in Year 5 preparing for the 2027 entry cycle, registration for the consortium test typically opens in January 2027. Watch the website of any consortium school for the official opening date. Preparation should ideally begin well before registration opens, so that by the time the September 2027 test arrives, your child has had 12–18 months of structured, progressive practice with the GL Assessment question types.
