I read this thread with interest, as we have recently been in a position to have to decide whether to send our son to an independent school for secondary in September.
We can't afford it, but my dad works there, has done for 36 (yes really!) years, and we would get the 2/3 (yes 2/3!) fee remission.
It's a very good school. My son is very sporty indeed, and also knows some of the kids who would be in his cohort as he attends the boarding activity weeks there in some holidays.
BUT. My partner (state educated, better degree than me) is fairly anti private education. We both teach in state schools. But crucially for us, the decision to send him to a state school next year had three major arguments in its favour.
My son has ADHD for which he is medicated, and I know that the new school will be VERY good at supporting him where he needs it (I work at the feeder primary, so know the SEN staff there; also I know parents of children already at the school who have nothing but positive feed back).
Secondly, we have moved house three times since our son started reception, always to different areas, so always necessitating a new school. He is very happy and settled with his very lovely peer group for the first time having spent more than two years in a school for first time.
Thirdly, although my son is very bright as we have recently realised (since medication, but have always suspected!
), he has gaps in his knowledge where he "missed" a lot of school due to his condition and is only now really catching up. We would have had to coach him in to my dad's highly selective school, and would be worried about him struggling from the start. Oh - and I forgot, fourthly - he would have to weekly board.
My son has attended the schools I have worked at since Reception, and when I worked in socially deprived inner city schools, hand on heart, do I think he received as good an education as he has at my current village middle class primary? Probably not. And not because my colleagues were any less good at their jobs. And would we have made a different decision re: secondary had we still been in those deprived catchments? Again, I think MAYBE not.
