Local pupils selected for grammar school at age 11 – about a third of all those who sit the test – have customarily attended Amersham and Chesham schools: Dr Challoner's Grammar School (boys), Dr Challoner's High School (girls) and Chesham Grammar School (mixed). New catchment areas were implemented by Buckinghamshire Local Education Authority in 2004 so that selected pupils may now attend The Royal Grammar School (boys), Beaconsfield High School (girls), or Wycombe High School (girls). Some selected pupils still choose to attend Chesham Grammar School and John Hampden Grammar School (boys) despite both now being out of catchment. In recent years, Year 7 children who qualify for grammar school under Bucks' late transfer procedure (known colloquially as "The 12+") have been able to win places at Chesham Grammar School.
