We have never experienced any issues or had to fight for his additional needs at all.
@MadreDeDios I would personally say that you were lucky.
We have had to fight tooth and nail for everything. We have had nursery out and out lie about the provision they were meant to be providing, we have had schools ask whether to prioritise the hearing loss or the subsequent behaviour, we have had a School place the only LSA they had that knew BSL into a different class to my Deaf child.
we have had to fight for 5 years to get a Local Authority to write the words "British Sign Language" into a statement/EHCP, we fought for over a year to get a LA to specify the words "qualified in BSL level 3 or above" in the provision.
So I would say that yes, a child starting a school with absolutely zero support in place does happen. And it happens a lot more than people think. It is only when things totally fall apart for that child that things begin to happen, and they don't happen quickly.
