Thanks TLP.
Been attempting to reword it today, but realistically the whole darn thing needs rewriting.
We have such beautifully specified provision as:
Ds1 will require access to ICT such as a laptop or computer ......
Ds1 will require support with developing imaginative writing skils, ensuring that he takes into account of the audience, using correct punctuation, editing and improving work that he has produced. (That's it - no suggestion of what for this 'support' will take.)
Teachers should be aware that he will require extra support with ............. elements of the curriculum. (Again no suggestion as to type of support.)
Ds1 requires support with self organisation so that it is clear what is expected of him and ensure that difficulties in this area do not impact on his access to teaching. For example, through not having the right equipment or not having handed in work. (Yet again, no suggestion how they will support him.)
It would be practical for his mentor to support with this during regular daily meetings as well as addressing emotional needs. (There had been no mention of a mentor prior to this point on the statement and they are effectively trying to cover two completely different areas of issue/support into one extremely vague point here.)
In order for ds1 to be ready to learn, his emotional difficulties need to be carefully managed and addressed. He requires access to a trusted mentor figure on a regular basis in order to explore any worries, social diiculties or misunderstandings that he has encounters. He benefits from having time to process his thoughts, talk them through, workt them out and feel listened to. Access to the mentor should be ofered on a regular and consistent basis. (Er ... how often, how much, when - not to mention who?)
In addition to providing support in reacting to and managing difficulties that arise, ds1 will also require ongoing support to develop his emotional understanding, self-regulation and social understanding. This support should be provided by an adult with knowledge and understanding of ASD. He will need regular sessions that focus on supporting him in developing skills in identifying his feelings, managing negative feelings ........ etc. (again, how often, how much?)
.... and that's just a small part of it. Every single point is along similar lines - not one 'will be provided with' 'will receive' or 'x number of hours' 'x sessions per week/month of x amount of time' or in fact anything that might even resemble an attempt to specify or quantify. 
I've been working through some sample statements and stuff from Treehouse, SOSSEN, IPSEA and ACE-ED and the other thing that really stands out is that the other statements all either state the objectives under section 3 then address each objective in turn or state the needs under specific titles in section 2 and then respond under the same titles in section 3. Ours has totally different section titles for 2 and 3 and there has been absolutely no attempt to match provision to specific needs or objectives, which makes the document incredibly hard to read, follow and make sense of.
Its is definitely ds1 specific in as much as much of the text has been lifted directly from my initial SA request - so at least its not just a rehash of a standard statement proforma or mis-mash of other statements for children with similar needs, but its like its been written by someone who has zero knowledge of SEN or the law relating to it.
I'm tempted to just write a statement the way I would like it to be and ask for a meeting to discuss which is better. Its got to be quicker than trying to make a silk purse out of this particular sow's ear.
