Janey McDowell, Head of Pre-Prep

BScHons (Reading), PGCE (Cantab)

As a child, Janey lived in many different countries. Born in Zimbabwe, she then lived, and was educated, in Sudan, Iran and South Africa. Janey’s career in education began by studying mother/infant relationships in orang-utans (!) whilst gaining a B.Sc. (Hons) Psychology/Zoology. This was followed by a P.G.C.E.(Biology) from King's College, Cambridge. Having taught A-level biology for a few years, she realised that it was the children's development that interested her more than the subject, so she moved gradually down the age range, eventually teaching a nursery class at Rupert House School in Henley for 12 years. When Crosfields became co-educational, Janey joined as a Reception teacher, before being appointed as Head of Pre-Prep in 2008.

Bringing up four children (three daughters and a son who attended Crosfields), has given Janey an insight into, and understanding of, parents' concerns and expectations.
