Admissions and catchment
Year 3 entry · Hertfordshire council allocation figures, 2023–2026
Add a postcode to see where you would sit against past cut-offs.
The furthest child offered a place in 2026 under the “Not Nearest School” rule lived 1.1 km from the school. Add your postcode to see where you would sit.
Why we say “Add your postcode”
- In 2026 the furthest child offered a place under the “Not Nearest School” rule lived 1.1 km from the school. Hertfordshire printed 1,064.62 m (allocation day).
- 146 applications for 90 places in 2026 (1.6 per place).
What could change this
- We measure a straight line from your postcode centre. The council measures from your home address, sometimes along walking routes, so treat anything near the line with care.
- Cut-offs move every year with the number of applicants and siblings.
- Children with an EHC plan, looked-after children and siblings are usually offered places before distance is used.
- Past allocations never guarantee a place.
Rings are to scale in straight-line km. Your marker’s direction is arbitrary; only its distance from the school matters.
