After speaking to my mum about applying for my primary school place in the mid 90s and some posts I've read on here, it seems that back in the 80s and 90s there was no centralised system for school admissions and you just rang the schools concerned who would add you to their list. It sounds like there were admission criteria of some sort, e.g. apparently the local Catholic school said you had to be baptised and the local C of E school said you had to be churchgoers, while the community primary automatically gave a place to everyone in the nursery.
How did this work in practice? Would schools have a set number of places and did they have to fill them (e.g. would the Catholic school have to take someone who wasn't baptised who applied if they still had places, like they would nowadays, or could they say no and leave the place unfilled?). Could they go over the admissions number if there were more local kids than was thought? Did they fill by first come first served or who met an admissions criteria best? What if all the schools you rang said no? It all just seems so different to today's preference system that is centralised and takes months to sort out.
By the time I was applying for secondary school in the early 00s the equal preference system that still applies today was in place in my LEA, so it seems like a lot changed in those 7 years!
