Yes, Section F is the Provision section and what you can hold the LA to account for. As is Section B (Needs), which must be accurate and comprehensive. And once Needs have been specified, Provision needs to be made to meet them.
The Placement section (Section I) is also obviously the other section you can go to tribunal over.
A lot of LA's want to put SALT in Health (Section G), but yes, make sure it is put in F, or they can wriggle out.
Other tips - get resources from IPSEA - they do a checklist of what should be in each section, plus get an Independent Supporter if you can to check it over. They will have seen load of the plans before so can offer advice.
Other tips - don't get your hopes up too high for a holistic approach - LA's are being very slow to get their heads round this.
Think of Outcomes (Section E) that YOU want, and then ask the people giving evidence for the EHCP to back you in those Outcomes and specify provision to meet them. Outcomes are not 'Harry has a one-to-one for 15 hours a week'. They should be more like 'Harry has two friends by the end of reception' or 'Harry can take part in afterschool clubs of his choosing by the end of Spring Term 2016'. The provision should then be that 'Harry is given an ASC-trained TA to facilitate play activities every break and lunch between Harry and selected children from his class, with support to be discrete and scaffolded to be reduced as Harry's ability to intiate and maintain social relationships grows. To be reviewed on a monthly basis'. Not a great example, but writing this is an hurry, sorry!
