Ds is only 4 and has a Revised FInal Statement (!) written by our lawyer, but with a certain amount of legacy from the inital one. It is very thorough now!
Part 2 starts with an introduction to ds, then his approaches to learning, communication and interaction (i.e. primary barriers to learning stem from his diagnosis and have an adverse effect on ... then pads these areas out drumming home need for 1:1), behavioural, emotional and social needs (drumming home need for 1:1) , sensory and physical needs (drumming home need for 1:1) and a summary of his SEN.
Part 3 lists his objectives (related to previous summary of SEN) and then sets out the educational provision to meet his needs and objectives (giving type of education required - i.e. special school, need for wheelchair accessibility, need for 1:1 and class size, need for close liason/seamless approach, role of SALT and communication approach, SALT provision, role of OT and physio and approach to lifting and equipment, OT provision, PT provision, developing play skills, developing choice-making, developing attention span, developing relationships, access to in-house clinics and outreach work in school holidays, access to summer school and after school and then also monitoring (IEPs and reviews) of all this.
Part 4 is school (obviously!)
Hope that helps. Can give you more specifics if you need better idea.
Firstly though you need to ask what do you want for your dd? Could you start with Part 4 and work backwards to start with? I think the rule is whatever you want in Part 3 has to be based on something in Part 2.
FWIW our Final Statement was rubbish too (despite delaying it a month by trying to get them to heavily revise it)- though it did at least name the school we'd wanted (we were an absolute pain to deal with in the period between receiving the draft and getting the final). Have sorted it out now though and am sure you will too if you persevere. All comes down to money at the end of the day.
