5. Quest Assessment vs GL Assessment

Quest Assessments and GL Assessment are two entirely separate testing organisations that both produce 11+ entrance exams for UK grammar and independent schools, and for 2027 entry — the cohort sitting tests in September 2026 for a September 2027 school start — the two are not interchangeable. They differ in delivery (paper versus digital), difficulty model (fixed versus adaptive), subject combinations, and scoring detail, and which one your child faces depends entirely on the specific school or local authority you are targeting. This guide sets out exactly what changes for your child depending on the provider, using real 2026 test dates for Bexley, Buckinghamshire and the Dorset consortium, and corrects two assumptions that even established 11+ advice sites currently get wrong about "Quest" and about which councils are actually switching this year.

Which Councils and Schools Use Quest vs GL Assessment for 2027 Entry?

GL Assessment remains, by its own description, the provider used by the majority of grammar schools in the UK, and it is the sole or primary provider for large grammar-school counties including Kent, Buckinghamshire, Lincolnshire and Gloucestershire. Quest Assessments, by contrast, is the established choice for more than 150 academically selective independent schools nationally, and has only in the last few admissions cycles begun replacing GL Assessment at individual local authorities. For the 2027 entry cycle specifically, the clearest example of that shift is the London Borough of Bexley, which moved its four grammar schools from GL Assessment to Quest Assessments starting with its 2026 selection test — meaning 2027 entry is only the second cycle sat under the new provider.

The Dorset row matters more than it looks. Several general advice sites have published "Dorset moving to Quest" headlines that families researching 2027 entry can easily misread. The move is confirmed, but it applies to the September 2027 test sitting, which selects for September 2028 school entry — not the cohort sitting in September 2026 for 2027 entry. If your child is currently in Year 5 targeting Bournemouth School, Bournemouth School for Girls, Parkstone Grammar or Poole Grammar for September 2027, you are still preparing for GL Assessment, not Quest. Only children currently in Year 4 or younger will be the first Dorset cohort to sit the new Quest format.

How Does the Test Format Differ? Paper, Digital, and Adaptive Questioning

GL Assessment is overwhelmingly delivered on paper, using multiple-choice questions and, in some local authority "standard" format tests, additional questions requiring a written answer. Papers are computer-marked, using optical scanning of answer sheets, and every child sitting a given GL paper answers the same fixed set of questions in the same fixed time — there is no adjustment for how well a child is doing as the test progresses.

Quest is genuinely delivered in two different ways, and this is the point most comparison articles blur together. Quest's digital format — the one used by the majority of its 150+ independent-school clients — is adaptive: the system selects harder follow-up questions when a child answers correctly, and the final Standardised Age Score takes into account the difficulty level a child reached, not simply the raw number of correct answers. But Quest's paper format, used by Bexley for its 2026 and 2027-entry selection tests and confirmed for the future Dorset consortium test, is fixed-difficulty, just like GL: children mark answers on a separate optical-mark-recognition answer sheet by drawing a line through a box, and every child answers the same questions in the same order. In other words, "Quest is adaptive" is true for roughly half of Quest's usage and false for the other half — a distinction that matters enormously for how a family should prepare, and one that generic "GL vs Quest" articles rarely make explicit.

What Subjects and Question Types Does Each Test Cover?

GL Assessment's core 11+ offering covers four subject areas: English, Mathematics, Verbal Reasoning and Non-Verbal Reasoning, though the exact combination and number of papers varies by local authority — GL itself notes on its own site that timings, subject combinations and question counts "vary from area to area," which is why families must always check their specific council's format rather than assume a national standard.

Quest is more modular: schools and local authorities choose which subjects to assess from English, Maths, Verbal Reasoning, Non-Verbal Reasoning, plus creative comprehension and problem-solving options that GL does not offer as standard. The paper-based Quest test used for Bexley consists of two papers, each roughly 50 minutes long. The confirmed format for the future Dorset consortium Quest test (September 2027, for 2028 entry) is three separate 40-minute papers — Mathematics, English and Verbal Reasoning — each multiple choice with five answer options (A to E), marked via an OMR answer sheet, and Dorset has stated that "no content beyond the Year 5 National Curriculum will be tested," a deliberate design choice aimed at reducing reliance on tutoring-heavy extension content.

How Is Each Test Scored? Standardisation and Age-Adjustment Explained

Both providers convert a child's raw score into an age-standardised score (SAS), a long-established method in UK selective testing that adjusts for the age gap between the oldest and youngest children in the same school year — without it, a child born in September would have a significant natural advantage over a child born the following August simply from being up to eleven months older on test day. Neither GL nor Quest publishes a single national pass mark; qualifying scores are set independently by each school or local authority, which is why Buckinghamshire's published qualifying score of 121 has no direct read-across to Bexley or any Quest-tested area.

Where the two providers differ is in how much standardisation detail they publish. Quest states that its scoring is standardised against a national sample of more than 40,000 pupils across the UK, and says it plans to introduce benchmarking against schools with similar demographic profiles as an enhancement. GL Assessment does not publish an equivalent current sample size figure on its consumer-facing 11+ site, though it has decades of national standardisation experience behind it as the successor brand to NFER-Nelson.

Corporate History: Which Provider Is Actually "the New One"?

A common assumption in 11+ forums is that GL Assessment is the long-established "traditional" test and Quest is a recent digital start-up. The company histories tell a more surprising story. GL Assessment's roots trace back to the National Foundation for Educational Research (NFER), whose testing arm became part of Granada Learning Group in 2000 and was formally renamed GL Assessment in December 2007. Quest Assessments Limited, meanwhile, was incorporated on 17 April 2008 — only four months after GL adopted its current name. As companies, GL Assessment and Quest Assessments are almost exactly the same age. What is genuinely new is not the company but Quest's expansion into mainstream local-authority grammar-school testing: Bexley's 2026 switch and Dorset's confirmed 2027 switch are recent commercial developments, not evidence of an inherently newer or less-tested organisation.

When Are the 2027 Entry Test Dates for Quest and GL Assessment?

Exact dates vary by local authority and school, so families must always confirm directly with their target school or council, but the confirmed 2026 dates for the areas covered in this guide illustrate the general pattern. Buckinghamshire's GL-format Secondary Transfer Test runs on 8 and 10 September 2026 (registration closing 2 June 2026, 3pm), with results released 9 October 2026 and the secondary school application deadline on 31 October 2026. Bexley's Quest paper-based test runs across a window from 2 to 10 September 2026 (registration deadline 31 March 2026), with results expected in early October 2026. Independent schools using Quest's digital adaptive format typically test later, across October 2026 to January 2027, reflecting the different application timelines independent schools operate to compared with local-authority grammar schools.

Why Is Quest Assessment Replacing GL Assessment in Some Areas?

Bexley's switch was described by the council as part of a routine review of its assessment provider, with Quest's test design selected for the 2026 cohort onwards; the paper-based delivery format was retained even though the provider changed, so the practical difference for Bexley families is a change in question style within a still-fixed-difficulty, still-paper-based test. Quest's own stated rationale for its Dorset consortium design leans on curriculum alignment: the company describes its aim as producing tests that are "accessible, academically rigorous, and effective in identifying potential" without relying on content that extends far beyond what is taught in the primary classroom — a deliberate positioning against 11+ tests that reward heavy external tutoring on obscure vocabulary or advanced maths. Whether that philosophy changes outcomes in practice will only become clear once results data from the switched areas accumulates over several admissions cycles.

How Should You Prepare Differently for Quest vs GL Assessment?

Start with content, not format. English, Maths, Verbal Reasoning and Non-Verbal Reasoning fundamentals overlap heavily across both providers, so strong core subject knowledge transfers directly regardless of which test your child eventually sits. Once content is solid, layer in format-specific practice, because the two formats reward different exam behaviours.

For fixed-difficulty tests — GL Assessment papers and paper-based Quest sittings such as Bexley's — the priority is speed and consistency across a known question range, since every child answers the identical paper and time management under pressure is the deciding factor between similarly able candidates. Full timed past-paper practice, ideally using format-matched materials rather than generic 11+ workbooks, is the most effective preparation method.

For digital adaptive Quest, sat by the majority of independent-school candidates, the priority shifts to sustained early accuracy, since strong performance in the opening questions unlocks harder, higher-scoring content, while an early mistake can route a child toward an easier question path with a lower score ceiling. Composure under an unpredictable question sequence, and comfort working on-screen rather than on paper, both need deliberate practice — a child who has only ever practised paper GL papers should not assume that preparation transfers directly to adaptive digital Quest. Families with children applying to a mixed portfolio — for example a Bexley grammar school and several independent schools — should budget time for both formats separately, starting structured preparation at least 10–14 months before the earliest test date. Families also weighing up 13+ options in parallel may find our Quest vs ISEB Common Pre-Test comparison useful, since some independent schools require both an 11+ Quest test and a later 13+ ISEB pre-test for different entry points.
