Yellowtip HB and CRGS are not your bog standard catchment grammar, are they? However feel free to call me absurd if that is the standard catchment grammar behaviour where your kids are happy in, which frankly would not be tolerated in the comps around here. Since you've taken a shine to them, you surely know that HB has a reputation as an exam factory, not just from possible sour grapes parents, but experienced teachers with unmatched results and destinations track records. CRGS we know well from family friends and their children. They rely significantly on their overseas boarders for results, and I can categorically say the pupils are not stellar, that perhaps expected from a grammar system county? However thankfully relatively normal.
seeker if a grammar cannot outperform a comp, and many do not, why should the state fund them for a limited constituency? As for independents, people buy for all sorts of reasons, they can spend their own money how they wish to, and they see something there worth buying.
I'm sure all our children are happy where they are, or we would change their circumstances. If yours fit, that's fine for yours. I'm curious from a policy viewpoint why choose a suboptimal option when another system delivers better outcomes.
The politics apart of making any change, why fund any top quartile selective that does not deliver what a equal banded four quartile comp does? And then, there is the question of adequate provision for the other quartiles who are also interested in preparing for worthwhile and rewarding lives ahead. Even if they are other people's children.
