So basically, your joint income is 60K and you get 10% reduction in fees from DC's grandparents?
We didn't have the grandparents help and we sent DC at reception private, on that income level.
We thought, if you wait for year 3 for 7+ entry, that's when all the middle class parents who use outstanding primary schools as free pre-preps join the mix and your DC will be competing with their offspring. You also have parents moving their DC around from pre-preps at 7+.
At 4+ the field is a bit clearer. By Year 3, your child (in any decent prep school) will be about 1 to 2 years ahead of state primary, if they are very bright, the school will accelerate their learning, so the 'value' is right there already.
These years are vital (4 to 11) and small classes, close attention from teaching staff, opportunities with a wide range of music, sport and lots and lots of school trips are so invaluable.
Yes, it will be hard, yes you’ll have to juggle things big time, yes most people will think you are mad.
Sending them to pre-prep at 4+ gives you options. ALL prep schools will have children whose parents are scrimping and saving, between now and 11+ who knows what your financial situation will be, but you're in the game so to speak. It also means your much more likely to get them into a grammar after years of prep school.
I know one set of parents at my DC’s school, dad has 2 jobs and mum had 2 to cover fees and keep a roof over their heads. Many will say they are mad, others like me would say tenacious. You can hope for bursaries and scholarship, but you have to assume that help wont come and come up with a plan - it sounds like you're doing that.
I won’t lie, sending DC private on a modest income , its really tough, and not for most parents, but it provides a strong example for your kids, they'll never forget, and it teaches them that with sheer gumption and insane hard work you can do anything in this life.
