@Cinnamoncupcake unless DS also has PDA, it is worth asking specific questions around that. Some schools who understand other types of SEN are not brilliant with PDA.
@1995SENNDMUM making a normal application doesn’t make any difference to whether the LA will name a MS in an EHCP even if your preference is SS. The process of naming a school in an EHCP is completely separate from the normal admission process.
There may be 5 MS within 2 miles, but if you don’t make a normal application and don’t get an EHCP, then need to make a late application, you may not be allocated one of those schools. They may be oversubscribed and you may be allocated a not so good school a long way away. Not a problem if you would EHE if you don’t secure SS.
It is unusual for LAs to agree funding for a full deferred year at nursery for autumn born DC without EHCPs outwith Specialist Early Years Assessment Places for those undergoing/needing to undergo the NA process. Presumably this doesn’t apply, otherwise you wouldn’t have just said nursery because reception is also part of the early years foundation stage.
As an aside, DWP can be as unpredictable as LAs. Renewals can be uncertain even for DC who definitely still meet the criteria. Some have to appeal even for DC with complex needs.
