Bucks 11 Plus vs Kent 11 Plus: Key Differences Every Parent Should Know
Bucks 11 plus vs Kent 11 plus — if your family is considering grammar school entry in both counties, or if you are trying to understand which system and preparation approach applies to your situation, it is essential to understand that while both are 11 plus tests for grammar school entry, they differ in several important ways. The test provider, the subject areas covered, the scoring approach, the type of grammar school system, and the competitive landscape are all meaningfully different between the two counties.
The Grammar School System: Buckinghamshire vs Kent
Buckinghamshire is a fully selective local authority — every state secondary school in the county is either a grammar school (selective) or an upper school (non-selective). Every child in the county is assessed through the same single test, and the result determines which type of school they attend. Kent is largely selective but the grammar school provision is not uniform across the county. Some areas of Kent are effectively fully selective; others have a mix of grammar and non-selective secondary schools.
Both Use GL Assessment — A Key Similarity
The most important similarity between the two counties for preparation purposes is that both use GL Assessment as their test provider. This means the underlying question types, the multiple choice format, the audio instruction format, and the age standardisation process are broadly similar in both counties. If your child is preparing for both tests, most of the preparation content is transferable. However, the specific papers differ. The Bucks papers include spatial reasoning as a distinct subject area, which may not be weighted as prominently in some Kent tests.
Scoring and Qualifying Thresholds: Important Differences
Both tests use age-standardised scoring on the same GL Assessment scale. The Bucks qualifying threshold is fixed at 121 and is the same for all 13 grammar schools in the county. Kent's approach is more varied — individual schools or clusters of schools may set their own qualifying threshold, and some Kent schools use ranking of scores rather than a fixed threshold. In the most oversubscribed Kent schools, children may need standardised scores in the 130s to realistically compete for places.
Key Takeaways
- Both Bucks and Kent use GL Assessment — preparation content transfers well between the two
- Bucks is fully selective county-wide; Kent's selectivity varies by area
- Bucks has a fixed qualifying threshold of 121; Kent's effective threshold varies by school and year
- The most competitive Kent schools may require higher effective scores than Bucks qualification
- Spatial reasoning is a specific Bucks feature — check whether it applies to the specific Kent test too
- Register separately for each county through the relevant local authority
Frequently Asked Questions
Can my child sit both the Bucks and Kent tests?
Yes. They fall on different dates, allowing both to be sat in the same September. Register for each separately through the relevant council.
Is Bucks preparation sufficient for Kent?
Largely yes for content, since both use GL Assessment format. Supplement with Kent-specific practice papers and research the specific schools' score expectations, which can be higher than Bucks' qualifying threshold.
Do Bucks and Kent grammar schools accept each other's test results?
No. Each county's qualifying decision applies only to that county's schools. A Bucks qualifying result does not give access to Kent grammar schools, and vice versa.
