Yeh I agree - what are the actual realistic options?
We live in a small city and if I wanted the DC to avoid two bus journeys to school (quite apart from the fact that the two-bus-journey school would not have offered a place) then there were (counts up) four secondaries that were within walking or one-bus distance. Of those, one has very different holidays from many schools (and I worked in a school so that would have been a pain); one was a religious school not our preference at all; one was a very popular school which is a 25-min walk to the bus stop so not ideal (and also unlikely due to immense popularity as we are out of catchment) and one was our local school, 5 mins away and where most of their friends were going.
I appreciate some may have more options – if you lived in the centre of the city for example, you could add many more to the one-bus-journey list – but even then, realistically the popular ones you might prefer are unlikely to fling their net that wide.
Not saying don't put an optimistic improbable option on your list, but also list your catchment or nearest school for sure.
We are not in a grammar area btw than goodness (I mean on purpose tbh – both DH and I went to grammar schools in very rural areas) so that's not an issue.
I would check the LA detail of distances offered and see which schools are actually likely - that 's a good starting point.
ETA: Can I just say, what I have said before on similar threads, you are not choosing a school. You can choose which coat you buy and what you have for dinner; but for schools, all you can do is state a preference. You could list six unlikely schools and be offered a place at a totally different school. This is unlikely if you follow the "list a banker" advice tho.
