How places are given
The two standardised scores are added together, and a combined score of 220 qualifies. Oversubscribed schools then apply their own criteria, so popular schools often admit children who scored well above 220.
How to register and apply
Register with the Lincolnshire grammar schools by the end of June of Year 5, and name the schools on your secondary application by 31 October.
Admissions rules change each year. Check the school’s current admissions policy — area details last checked October 2026.
