My understanding is a computer does all the work ... For each school, ranking all applicants then for each child, looking at each choice in turn, starting with the first, until it finds a school where you rank highly enough to be offered a place If you are eligible for more than one school, your offer will be for the one you chose higher up your list It was more of a gamble when southwark gave priority to 'closest community school' above straight forward distance because if your closest community school was your first choice, you could get in ahead of other children who lived closer (but for whom another community school was their closest) So not putting your closest school first was a bit of a gamble That criterion no longer exists
