It's a resounding no. I asked the question, "Do most children stay here at 11 or do they move to the grammars or other schools?". They looked at me like I had asked the most ridiculous question. 99% stay on throughout the whole school with only a couple leaving at 11. There are numerous other prep schools in the area that do prepare for 11+, 13+ and common entrance though.
Thank you very much Zodlebud. I did know some schools around but couldn't determine which ones to go for. Edge Grove seems to have mixed reviews. Manor Lodge looks good but I am not sure whether my son will get in during the assessment as he is generally very quiet and need some time to open up. Aldenham is said to be not very academically competitive (some may not agree but I didn't see the data of feeding to top senior schools). Would you please recommend some good prep schools which do prepare for 11+ or 13+? Thanks a lot!
Have a look at Beechwood Park and Westbrook Hay as forerunners. Chesham Prep and York House are lovely but don't seem to have much "punch". Boys only then Lockers Park or Aldwickbury. The Beacon in Chesham also has a good reputation but quite sporty.
