It's not clear on their website from what I can see but I've also seen a lot of adverts in the local press during the past few weeks about DVIS changing their admissions policy for the year 2019/20. If that's the case then probably Dulwich Hamlet will probably change theirs soon and not by just distance. It seems a lot of schools in the area are changing their admissions policies to not just go by distance but if they have a staff member, then that member of staffs children have priority, even if they live outside the area?
