There's a map of Buckinghamshire school catchment areas here: arcg.is/1TfLPP. Many of them coincide with the borough boundary.
I've been reading up about the Greenwich Judgement on Wikipedia here: en.wikipedia.org/wiki/Greenwich_Judgement. It says that catchment areas are allowed, and that they can follow the borough boundary, so long as there is some reasonable justification for it, other than "it's the borough boundary and we want to prioritise places for children in our borough".
So what is the justification for Buckinghamshire schools to have catchment areas coinciding with the borough boundaries? Has anyone ever challenged them on it?
