Full-time 1:1 can be included in F. The school isn’t being truthful. However, many have to appeal. Lots of LAs say they don’t do 1:1 anymore - ignore!
You need to look at the wording very carefully. I know you think it is worded well, but many parents don’t realise the wording is not detailed, specified and quantified until the provision isn’t provided and they try to enforce it and can’t because it is vague and woolly. For example, look for 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)”, “adult support”, “small group”. This wording is too vague and woolly.
You can request an early review in order to try to amend the placement. The LA may not agree.
If you are still within the appeal window, you can appeal.
