To add controversy upon controversy, I support single sex education for girls (although boys don't fare as well), and as I live in a small city, there is no single sex state option.
In private school, my children get
*smaller classes (my older daughter can't concentrate to save her life, but flourishes with the attention she gets in the small class)
*fantastic 1-to-1 attention (see above)
*incredibly supportive, relaxed teachers
*slightly longer school day so I can be at my desk at 8.30am and really affordable after school care (although we don't use it)
Going private gave us choices.
In my city, the houses in the catchment for the AMAZING state school here are through the roof. Just looking at the map for the catchment area now, actually, I understand why some areas that I wouldn't have thought were all that great have such crazy prices. For much of the catchment area, although not all, a three bedroom house starts at about £1.1m. Sending my children to private is a BARGAIN compared to that carry on. We couldn't afford to live in the other catchment area.
There are some MAD PARENTS at the private school though. MADMADMADMADMAD. Much madder than at our old state primary. But they're a minority (I think). But talking about other crazy parents is one of life's little pleasures, right?
