when dd1 started school we googled town/ school and there were two. one was catholic and we aren't, so we applied to the other one.
then we moved and there was one school in the villagre where we were living, but it was 80% ESL, or a school in the other village which was full of white middle class children. we went for the nearest and were a bit worried about the ESL issue, but the support was fabtastic.
then we moved and we googled town/ schools again. so there were a few but the catchment school was in special measures. we visited in and the HT told us that our children (dd1 needed y2 place and ds1 needed a yr r place) would not be sufficiently stimulated and we should not send them there. so we chose the next nearest school to the house, and the next next nearest as a back-up. we had to be waiting list as there were no spaces.
then dd1 went to juniors in the next county (the y3 place for our address was still the all-through primary that the HT had told us not to send her to) as she wouldn't have been allocated a place anywhere within walking distance. and dd2 started at the same school as ds1 (who was yr 2 then).
then we moved again and there was only one school within a 45 minute drive, so they all went to the same one. it was bliss.
then we moved again and there was a state or catholic option. the catholic school couldn't confirm whether they could take ds1 until mid-sept, so we went for the state options. so dd1 is at the elementary and dd2 and ds1 are at the middle school.
i think choice is a bit of a luxury.
we've been fine just going to whichever school was nearest tbh (with the exception of the one the HT told us not to go to lol). dd1 is in her sixth or seventh school (i lose count) in yr7, sue to our moves, but she's happy, well adjusted, and on the regional register for more able children.
(as are the other two but they're only in third schools or whatever)
so no huge advice really. most schools are fine. and no choice is forever. having siblings at different schools is a pita. with the exception of sn, i wouldn't bother, for your sanity.
