If you're considering sending your daughter to Kensington Prep, it's probably best not to pay too much attention to an obviously disgruntled former parent or two.
Of course nowhere's perfect and improvements can always be made. It was a shame that the excellent head of science left, but she'd spent six years working for the current head and has left the teaching profession entirely - make of that what you will.
The former head of sport was completely out of her depth, however, and this was evident when she was on maternity leave. Her maternity cover was a noticeable improvement. No loss there and I wouldn't be surprised if she was managed out.
The longstanding head of music (Mr B) who left a few years ago, was a one of a kind and very well liked by students and teachers alike. The more recent head of music (Mrs R) was a marmite character, to say the least!
As a previous poster mentioned, this is London and turnover is to be expected.
Unfortunately some parents believe that paying fees at a West London prep school should guarantee their daughter entry to their school of choice. Naturally these types see no shortcomings in their own offspring!
Teaching has similarities to managing a football team - drunk bores in a pub think they can do better than a Premier League manager, except it's snarky messages on WhatsApp or Mumsnet with parents for teachers. That's not to say that teaching can't be improved, but is it a case of grass is greener elsewhere? Possibly..
On the whole, the seven years my daughter spent at Ken Prep (six of which was under Mrs H's leadership) was a highly positive experience. Bullying was never a problem or ever spoken about, at all. Was it really bullying or a highly irritating girl who annoyed everyone in the year group and struggled to form friendships because of this?
Tutoring is unfortunately rife at all West London prep schools. On the whole it probably makes little difference to the outcomes. Some parents tutor (I include parent 1:1 study time as tutoring - it's the same) because they have unrealistic expectations of their child. Other parents feel they need to do it so their child isn't at a disadvantage. The impact is probably marginal at best.
In summary, Ken Prep's a school that's well worth considering and is mostly attended by girls who live within walking distance of the school, giving it a local community feel. Having outside space for netball courts onsite is also a bonus that few central London schools can offer.
Good luck in your school search!
