FFS Tarano17, perhaps read my posts. No, I don't work for the LA. I do, however, have 2 DC with EHCPs, have advised many on MN over the years under various NCs and IRL. Where I have discouraged the OP from applying for an EHCP? (Taking in to account I have posted EHCPs do not exist in Wales)
I have pointed out, more than once, EHCPs don't exist in Wales. OP can not apply for an EHCP when they do not exist in Wales. As OP posted she can not apply for an IDP until January. As a post 16 pupil during the ALN reforms I don't believe she is now able to apply for a statement of SEN, and even if she could it wouldn't be quicker than waiting to apply for an IDP on the 1st January as 26 weeks (the legal timescales for a statement of SEN) from now is after 12 weeks (the legal timescale for an IDP in a FEI) from the 1/1/22. I also advised her to get in touch with SNAPCymru who provide a similar service to IPSEA but for Wales.
as well as transport provision
As per the case law I posted, transport is not an educational need and should not be in EHCPs unless there are exceptional circumstances. And post 16 transport rules are not the same as the law for CSA pupils.
I provided a link to IPSEA stating an EHCP wasn't necessary to secure transport, because there is seperate statutory requirements that cover SEN and disability. If you believe an EHCP or statement of SEN/IDP is required perhaps you can provide a reputable link proving IPSEA wrong?
The processes of applying for an EHCP, IDP and statement of SEN are governed by statutory timescales, 20, 12 when in an FEI and 26 weeks respectively. These must be stuck to regardless of any "very long wait for LAs to process" them.
