I noticed that the schools outside the Bucks (even when they have been administering theses for years) don't really know what they are supposed to be doing. Do they not get any information booklet?
The school is under no obligation to invigilate these tests, it merely does so as a favour to parents for which I shall be forever grateful! Having said that, since it is so close to the county boundary there is always a possibility that some of its own pupils might live in Bucks so presumably then there might be some duty to hold the test for these pupils, but not otherwise. There is certainly no advertisement of the fact that this happens - parents tend to find out about the option mainly through word-of-mouth (as was the case with us a number of years ago). The apparent fluidity of catchment areas across Bucks county boundaries (e.g. Berks, Oxfordshire, Herts etc.) does not seem to apply in the north of the county!
