"Parents who like grammars probably do for the same reason as private schooling. It's that sense of privilege and being "better" than others and not wanting their children to mix with "rough kids". That's my sense."
@believeitornot - we chose the grammar schools for ds1 and ds2 because we felt that they offered the best education for the boys, and suited them best. Their catchment comprehensive was not as good academically, and had discipline problems. And both ds1 and ds2 wanted to go to their respective grammar schools, because friends were going there and, in ds2's case, because it was a very sporty school, and he loves sport.
We chose the schools we thought would be the best for our children - isn't that what most parents do? Is it wrong to want the best possible education for your children?
I should say that we didn't get ds1 coached for the 11+ - our view was that, if he couldn't get in without being crammed for the exam, he wouldn't be able to cope once he was there. We did get ds2 coached - though, in hindsight, he didn't need it. His best friend was coached for the exam by his mum, using the Bond 11+ practice books, and he got in too. So it is possible to pass the 11+ without expensive coaching.
We offered the coaching to ds3, but he found it too much, on top of school (it was only once a week, but he fell behind on the homework and got too stressed), so we let him drop it, and offered help at home. He decided he'd do the exam, but was happy to go to the comprehensive, and again, we thought if he couldn't get in without lots of coaching, he wouldn't cope there.
As it turned out, we moved from Essex to Scotland when he was in Year 6, and we chose a house near a good comprehensive, whichnall three attended, and where they all did well, so the 11+ thing was moot in his case.
