Has DS had a home OT assessment? That can look at making the house better meet DS’s needs. For example, they can help with a specialist bed so that if DS smears, it is somewhat contained and not all over the room.
When is your hearing date? Have you requested an expedited hearing?
When did DS turn 5? Was it last year or this year? If last year, he is already compulsory school age. If he can’t attend school full-time, the LA is responsible for ensuring he still receives a suitable full-time education. Have you requested alternative provision? If DS turned 5 since the start of the year, he won’t yet be compulsory school age, so whilst the LA has the power to make alternative provision, they don’t yet have the same duty to under section 19 of the Education Act 1996, so they mostly don’t. But DS will be CSA from next term.
Is DS receiving everything detailed, specified and quantified in F of the EHCP? The LA is still responsible for ensuring that is received even if he can’t attend school.
Have you had social care assessments? A carer’s assessment for you and an assessment via the children with disabilities team for DS.
Depending on DS’s needs, have you considered if he would be eligible for children’s continuing care funding?
