I would say a definite YES
We moved our ds into a fantastic Prep school at the beginning of this year and believe it is the best thing we have ever done for him.
He was being bullied at his previous state school and the school did nothing to help him or us.
He has come on leaps and bounds since being in a class of 16 rather than 32, has specialist teachers in Science, Geography, IT, French, Music, Art etc and receives 10mins of prep every night on a subject they have studied that day in school (so all relevant to what he is studying) They have games,athletics or PE lessons everyday (which to a young boy who loves sport is totally fantastic!)
He reads to a member of staff every day! and on a Thursday gets to read to the Head!! The staff are available at the end of everyday for a chat if I have concerns and nothing ever seems to much trouble for any of them.
To me, this school is how my State primary was run back in the 70's. Good manners are expected, High expectations of work, respect for others and the teachers, something that I can assure you were not to be found in my sons state school.
His prep school also extends beyond the national curriculum as the children study the Common Entrance syllabus.
we were all for private education at senior level and believed that would be sufficient for our son to succeed however seeing how his school is instilling in our ds now the love of learning, how to study correctly, independently and as a group/class and how much time the teacher can devote to our son we are so happy that we have moved him.
However fees are the big topic here..... the do go up a big amount. Our daughter starts reception in the pre-prep this Sept and her fees will be £1400 but the jump to Year 1 is huge and by the time they are in the Prep dept its £3000 a term plus the fees increase at the beg of each new school year (sept) be 100% certain you can afford the fees. Speak to an independent financial advisor regarding paying for schooling. Plus are you 100% certain of no further children? We were told after our DS's birth that we would be unable to have any more children, yet just before my sons 5th birthday his sister arrived!!
Plus are you willing to go back to work full time just to finance a place at the school?
Private school have very long holidays, my son breaks up this Thursday for end of lent term and has a whole month(!) off school and returns on the 22nd April. Also summer holidays last for 8 weeks, thats a long time to be off school and you would have to work all through that time and arrange child care which would cost too.
Do think hard about it, as for all my praise of my sons prep school, if I could find a state school which gave even a little of what I have found in his prep school , I would look at it!
Best wishes
