  It still needs more work because the area of the school grounds is not obvious on the Bing imagery. Normally the amenity=school tags are placed on the area covering the grounds, with the buildings just marked as building=school. In this case I've put the school info on the building.
  
  Also are the paths currently marked still usable? I presume at least some of them run through what are now the school grounds.
