I've just been reading an article in a local 'services for kids' type magazine about at prep school in the area that is going to offer fully integrated care from 8am-6pm 51 weeks of the year, with optional sessions 6am-8am and 6pm-8pm! It's going to be charged monthly at £500pcm (for the whole lot- not just the wraparound) like nursery fees.
The school terms are also going to be different to the state sector so parents can take family holidays outside peak times.
Wouldn't suit us as DH and I are both teachers but I can see it appealing to lots of working families. If a few schools start offering services like that how long before they all will?
