You need to look at what provision is in F of the EHCP. For example, what therapies are in there e.g. OT (including SIOT), SALT, MH therapies? What support is there for emotional regulation and social communication and interaction?
Look carefully at F for vague and woolly wording such as “access to”, “would benefit from”, “regular”, “up to”, “or equivalent”, “opportunities for”, “as appropriate”, “would be useful/helpful”, “such as”, “e.g.”, “etc.”, “as required”, “as advised”, “key adult(s)”, “small group”. Provision must be detailed, specified and quantified, otherwise the EHCP isn’t worth the paper it is written on and cannot be enforced. If you find wording like this you should appeal.
If DD is to remain on a part-time timetable, a) alternative provision needs to be in place. This should have been in place long before now, and b) you need to appeal the EHCP.
Is the current placement, the placement you wanted naming in the EHCP?
DC with EHCPs can still sometimes be suspended.
