Seeker doubt it is a private school they do not tend to have any training days or days off during the term time as the parents would have to organise care for their children and would be very concerned that they are paying for a day when the children aren't in. Training days at private schools are usually done during the long school holidays
Targets turn out to be for things like recognising & writing their own names, counting to 10 etc. I actually asked about them as the teacher didn't mention them, she said they're only for the few that can't do the above already.
She did say that dd has been put on g&t for literacy fairly sure that's just because she could read when she started though - I thought g&t didn't exist in reception.
