GL Assessment vs CEM: Understanding the Two Main 11 Plus Exam Boards
Key Takeaways
- GL Assessment uses separate, predictable papers for each subject; CEM blends subjects and changes format yearly.
- GL areas include Buckinghamshire, Kent, and Birmingham; CEM areas include Warwickshire and Gloucestershire.
- For GL, practise specific question formats systematically; for CEM, build breadth and vocabulary through wide reading.
- Check your target school’s admissions page to confirm which exam board is used.
One of the first questions parents ask when beginning 11 plus preparation is: which exam board does my area use? The answer matters because GL Assessment and CEM (Centre for Evaluation and Monitoring, based at Durham University) take very different approaches to testing. Understanding these differences shapes your entire preparation strategy, and can prevent weeks of wasted effort on the wrong material.
GL Assessment and CEM are the two main 11 plus exam boards. GL uses separate, predictable papers for English, Maths, Verbal Reasoning, and Non-Verbal Reasoning. CEM blends subjects together and changes format each year, making it harder to prepare for with past papers. Preparation for GL focuses on specific question formats, while CEM preparation emphasises broad skills, vocabulary, and quick subject-switching.
How the GL Assessment Format Works
GL Assessment papers follow a structured, predictable format. Each subject is tested in a separate paper with clearly defined sections. A typical GL exam includes four papers: English (comprehension, spelling, punctuation, grammar), Maths (arithmetic and problem-solving), Verbal Reasoning (word codes, analogies, sequences), and Non-Verbal Reasoning (pattern recognition, spatial reasoning).
Each paper is usually 45–50 minutes long with multiple-choice answers recorded on a separate answer sheet. Because the format is consistent year to year, targeted practice can significantly improve scores. Areas using GL Assessment include Buckinghamshire, Kent, Lincolnshire, parts of Essex, and Birmingham.
How the CEM Format Works
CEM papers are deliberately harder to prepare for. Subjects are blended together, a single paper might mix English comprehension with verbal reasoning questions, or combine maths with non-verbal reasoning. The papers change format each year, so past papers are not reliable predictors of what will appear.
CEM exams typically involve two papers of around 45 minutes each. Questions are often time-pressured, with more items than most children can complete. This is by design, CEM aims to identify ceiling ability. Areas using CEM include Warwickshire, Gloucestershire, parts of Devon, and several London borough grammar schools.
How to Find Out Which Exam Board Your Area Uses
The simplest way to find out is to visit your target grammar school’s admissions page. Most schools state whether they use GL Assessment, CEM, or their own bespoke papers. Your local authority’s secondary school admissions page will also confirm the testing arrangements.
If you are applying to schools across different areas, be aware that you may need to prepare for both formats. This is more common than parents expect, a family in south-west London might apply to both GL and CEM schools within a 30-minute drive. EdifyPod Nexus covers question types from both exam boards, so your child can practise the right material for every target school.
How Preparation Strategies Differ
For GL Assessment, focused practice on each subject and question type pays dividends. Work through the specific GL question formats systematically: learn the codes for Verbal Reasoning, practise the exact NVR question styles GL favours, and build speed with GL-format timed papers. Specimen papers from GL are available and closely match the real exam.
For CEM, breadth is more important than depth in any single question type. Focus on wide reading to build comprehension speed, strong arithmetic fluency, and exposure to varied reasoning question styles. Because CEM blends subjects, practise switching between question types quickly. Vocabulary is particularly important in CEM exams, where unfamiliar words appear frequently in comprehension passages.
Frequently Asked Questions
Which is harder, GL Assessment or CEM?
Neither is objectively harder, but they test differently. CEM papers are harder to prepare for because the format changes each year and subjects are blended. GL papers are more predictable, which means targeted practice is more effective. The difficulty of any exam depends on the individual child’s strengths.
Can my child prepare for both GL and CEM exams at the same time?
Yes. The underlying skills, comprehension, arithmetic, reasoning, are the same for both. What differs is the format and emphasis. Practise core skills broadly, then add format-specific practice for each exam board in the final months. EdifyPod Nexus covers both GL and CEM question styles.
Are there past papers available for GL and CEM exams?
GL Assessment publishes official practice papers that closely match the real exam format. CEM does not release past papers and deliberately varies its format each year, making third-party practice materials the main preparation resource for CEM areas.
