DD changed schools from one private prep to another this year. The new one is run by a charitable trust whose charter is to provide 'affordable' education for local children.
Fees for the new school are less by c.£700 a term, however:
No wraparound care - there is a breakfast club from 8.30 and an afterschool club but only til 4.30, so no much use if you're working (old school began at 7.30am for breakfast and finished at 6.30pm, included in the fees, and a hot tea - usually pasta or beans on toast - was served if you were still there at 5.30pm).
No school dinners, everyone must bring a packed lunch - this is a huge bonus for DD as she prefers sandwiches and hated the compulsory dinners at her old school, but a total faff for me.
No swimming - her old school gave yrs 3-6 a swimming session for one term each year, included in fees.
School trips have to be paid for by parents, they were inclusive in her old school.
Lots more fundraising activities (however there isn't much pressure to take part so far!)
Uniform cost is more expensive and more inconvenient as the only shop that sells it is 12 miles away around the North Circular, but they do come into school three times a year and you can get them to deliver to the school if you order online.
However, the new school is a so much happier, more human place!
Things common to both schools:
Music/singing lessons are extra and no instruments are available from the school to borrow or hire (when I was a kid our state school had a stash of instruments you could borrow while you were taking lessons, no idea if this still goes on!)
Lots of kids getting outside tutoring for maths/11+/common entrance exams. Whether this is needed or not I don't know, but there's something about private preps that seems to induce a collective utter paranoia that your child is somehow missing out and will 'fail' if it isn't being tutored and the rest of the class are.
Lots of emphasis on extra-curricular activities to put on their CV - again, parent induced madness, but you can find yourself signing little Sophie up for hockey and tennis and choir and debating club and latin and gymnastics and several different instruments in order to pass muster at the secondary school interview if you're not careful...
