GL Assessment (used by most grammar schools)
• Standardised, multiple-choice papers in English, Maths, VR and NVR
• Fixed pass mark set by each school or consortium
• Widely used across Kent, Buckinghamshire, Warwickshire, Birmingham, Lincolnshire and other grammar regions
• Past papers and familiarisation materials are publicly available
• Preparation tip: Practise under strict timed conditions — GL papers are tight on time
CEM / Cambridge Select Insight (no past papers)
• Used in some grammar regions including parts of Buckinghamshire, Gloucestershire and the Wirral
• Tests English (comprehension, SPaG) and Maths alongside VR and NVR
• No official past papers are published — this is by design, to test genuine ability rather than rehearsed technique
• Questions are interleaved (VR mixed with English, NVR mixed with Maths) rather than in separate sections
• Preparation tip: Focus on building strong underlying skills rather than drilling specific question types
ISEB Common Pre-Test (online, adaptive)
• Used by over 100 independent schools including Eton, Harrow, Winchester, Westminster, Wycombe Abbey
• Online test that adapts in difficulty — questions get harder or easier based on the child's answers
• Tests English, Maths, VR and NVR in a single sitting (approximately 2.5 hours with breaks)
• Taken in Year 6 or Year 7 depending on the school
• Preparation tip: Children cannot go back to previous questions, so teach them to commit and move on
School-Set Papers (bespoke)
• Written by individual schools and unique to each — hardest to prepare for generically
• Common at highly selective independents (e.g., St Paul's, City of London, Latymer Upper)
• Often include extended writing and more demanding comprehension
• Preparation tip: Request specimen papers from the school and analyse the exact format, mark scheme and timing
