Oldest has just started primary school. We went to look around a load but it was always going to be our local one, I'd do the same unless it is total shite. I figured even if one other local school had a good reputation they could always lose it in the next 5 years anyway. Some parents asked really in depth stuff about what kind of phonics teaching they do, I was more interested in how it all looked and the layout of the place. Pro snob tip - walk past in the mornings and afternoons to see the quality of the parents and the little shitbags.
Here they did it on location, right down to how many yards your house is from the school. They even published past figures on how close you needed to be. Some of the good ones only took kids from as close as 250m. Others have catchment areas. We had to pick a top three, risky as if they were all full then they just allocate you a school. Which would be a really shitty one miles away. I'd have a plan B.
