What does this mean?
This is the Department for Education's own published comparison of first preferences with total offers recorded. It indicates the level of requests made through coordinated admissions. Offers are not necessarily the school's maximum capacity, admissions arrangements vary between local authorities, the figure is not a measure of school quality, and it should not be used on its own to judge the likelihood of gaining a place.
