It isn’t enough. For example,
60 mins of SALT - how frequently, focusing on what, 1:1? - although this would often come from a SALT assessment in more detail. Has DS had a SALR assessment?
60 minutes structured and supported social interaction with peers - how frequently, by who (and their training/qualifications/experience), where/when (e.g. in the classroom, in the playground), how big a group (with 1 other peer, 5, 10, the whole class), will DS need 1:1 within the group? Again, a SALT assessment may expand on this.
a consistent trusted adult and support worker - what adult? The receptionist, a volunteer, the cleaner? Will it be 1:1? How long for? Where will they support DS? What will they do?
All provision that is not quantified must be provided by staff throughout his day - all provision should be detailed, specified and quantified. Depending on exactly what is written, ‘for the whole school day’ can be better wording.
when his behaviour requires it - to vague and woolly. Who will decide when it is required? DS may need receive it at all.
is this similar to "waking day curriculum"
No. The term waking day curriculum isn’t so much used now. But it is about needing provision beyond the typical school day.
