If you live in the catchment area and want an Oxbridge-tier education at zero cost, AGGS is the gold standard in the North West.
Altrincham Grammar School for Girls is highly aspirational, proudly intellectual, and fiercely meritocratic. National Rank 61= (A-Level) and 65= (GCSE) from a school that charges zero tuition fees. The most sought-after state grammar in Greater Manchester — but qualifying is only the first hurdle. In 2025, every single offer went to an in-catchment applicant.

Best For
A self-motivated, academically strong girl in the Altrincham/Trafford catchment area who wants an Oxbridge-pipeline education at zero cost. Must be comfortable in a fast-paced, high-expectations environment.
Watch Out For
In 2025, 1,482 girls sat the exam, 389 qualified — and every single one of the 208 offers went to in-catchment applicants. Qualifying is not the same as getting a place. Catchment distance has tightened sharply from 11 miles in 2021/2023 to 5.53 miles in 2025.
Entry Points
- 11+ (Year 7, ~204–208 places)
- 16+ (Sixth Form — GCSE-grade based entry)
The Complete Admissions Timeline
Every key date, deadline and decision point — with insider intelligence you won't find on the school website. Click any item to reveal verified insider knowledge.
The critical window: The Trafford Consortium 11+ is a single-stage, single-day examination. No interview, no taster day, no second chance. Two papers of approximately 60 minutes each covering Maths, Verbal Reasoning, and Non-Verbal Reasoning — all multiple choice. Speed is the true differentiator: the GL format is notoriously tight on time. Achieving the qualifying score is only the first hurdle: for 2025 entry, all 208 offers went exclusively to catchment-area students. The CAF (31 October) is a mandatory separate step — if AGGS is not named, no offer can be made regardless of score.

AGGS vs Competitor Schools
How does Altrincham Grammar School for Girls compare to the schools your child is most likely also applying to? This analysis covers the key factors that actually matter to families.
Important context: The key differentiator for AGGS vs. independents is cost: identical or superior academic outcomes at zero fees. The key risk vs. other grammars is catchment — AGGS is the most oversubscribed Trafford grammar.

Points to Consider
- Catchment is now 5.5 milesDown from 11 miles in 2023. Many families who bought homes in 'catchment' based on historical data may no longer qualify.
- Qualifying ≠ offerIn 2025, 389 girls qualified but only 208 received offers. All offers went to in-catchment applicants.
- No out-of-catchment offers in 2024 or 2025Recent years show zero flexibility for out-of-area applicants regardless of score.
- Intense academic pressureThe peer group is exceptionally able. Girls who are strong but not among the very top may find the pace challenging.
- Registration closes June Year 515 months before National Offer Day — a critical date most families miss entirely.
