Depends on score and which school. Bexley if you get top 180, no distance requirement. If regular pass then it goes on oversubscription criteria and distance matters. It would be a bit of a mad scramble if they pass and you need a rapid move. For Bromley, St Olaves have no distance criteria it is score only. Newstead has a nine mile criteria and I gather you can only sit the test if inside the 9 miles. You submit the SIF to apply to sit the tests in the summer before they start at secondary. Whilst the SCAF is submitted at end of October some address changes are taken into account and there are cut offs. Check each borough's timeline on their moving onto secondary booklet eg http://www.bromley.gov.uk/downloads/fil ... 15_booklet
. Bexley have a similar one but I don't have the link to hand.
