Unfortunately south of Broomwood is a black spot for the BTC schools. If you are the Broomwood end of Wroughton, Hillier, Devereux etc then you are in with a bit of a chance for Honeywell/Belleville I believe, but it will depend on how many siblings or closer first children there are that year.
If you are the Thurleigh end of these roads, or even further away (on thurleigh or roads south of thurleigh) there is little chance of Belleville or Honeywell I think. Extraordinary since they are so close but just a sign of the demographic round here
.
The schools mentioned by the poster above have bigger catchment areas as they have fewer applicants, so you may be in with a better chance for those, even though they are further away.
Just one thing to note - the council is consulting on moving to a "straight line" measurement of distance rather than "walking route" distance, it's possible this might help eg if you have a wiggly route to school.
