MmeBlueberry - that's v interesting and helps to put this in perspective a bit. Staff have left for varying reasons - ill health, getting married (2 of them), wanting to do further study and one for retirement.
In DCs previous pre-prep., staff turnover was v low, loyalty to the school and head excellent and there were only about 10 to 12 children in each class with a TA shared over two classes per yr group too.
This Prep. is v different - much bigger, much larger class size and this incredibly rapid turnover of staff - well, rapid in my mind. I wonder if it's that they're recruiting less experieneced, younger staff who are at a different life stage and therefore more likely to move on?
However, DS2 has had 7 different teachers for one subject since Sept. because of the newly recruited teacher being regularly off with poor health (now left), various other staff filling in day by day and finally a new substitute appointed recently - but she's only staying till the end of the summer term.
DS2 has had to adapt to different personalities teaching in different ways, with different expectations. Lucky for him it's his best subject but others in the class have suffered more.
Another issue if how the parents get to know about staff leaving. The children are told first, informally and then come home and let you know in passing, with no further info. from the school until just before the staff member goes, when there's a quick note to parents about it. I'd feel more reassured if there were a well-considered letter coming to parents, pre-empting their concerns and assuring that good continuity of learning would continue. The fact that there hasn't even been 'lip-service' paid to this worries me.
This is an academically selective school (yrs 3 to 6) where the larger class size is 'sold' as a good thing, as all the children are supposed to be able to work independently and rapidly and kick off ideas with each other.
In practice, the v v bright children (NOT my DCs!) don't get enough stimulation to move on even further, as the teacher just doesn't have enough time - or perhaps, because of staff turnover, doesn't even know the children so well. The less than brilliant children, some of whom struggle perhaps with one particular area or subject, have little time for one-to-one help and get left behind.
DS1 - who struggles in one particular key subject - told me that the other day he put up his hand at the beginning of a lesson to ask a question and despite raising his hand first of several children, was the last to be attended to. So he 'lost' the whole lesson, unable to get on with his work.
As I'm a single mum, single-handedly funding 2 lots of private school fees and meanwhile running a f/t business alone as well, I need to be able to trust that my investment is a good one and I'm beginning to doubt this.
I think I need to have a word with the Head and see if I can get some reassurance about my concerns. It sounds as if class size is rather higher than average, from the feedback here and also the staff turnover fairly high too, as some have left after only a year.
