Hope this helps, I did standard IPSEA letter, listing difficulties and dx's.
All reports, IEP's etc that I enclosed, school already had copies of so was pointless holding back.
Then My reasons for believing that the school cannot on their own make the provision required to meet my child’s needs are as followings:
Ds has failed to make adequate progress with the extensive support he has and a Note in Lieu.
The level of support that ds requires is more than can be provided for from within the schools own resources.
There are too many areas of need and his needs are too complex for school to manage without the aid of a statement.
I then did sub headings Attention and listening, verbal comprehension, expressive language, cognition and learning, social interaction/understanding, self help, flexibility of thinking/routines, anxiety/phobias/emotional, delayed play, sensory/motor and visual impairment.
Example under expressive language I have written;-
Expressive Language – functional ability
Although ds can achieve average scores during formal assessment, this does not describe his functional ability. From 2009 to 2011 various professionals all identify difficulties in this area (enc 1). I see similar behaviour at home and have not seen any improvement. . This area remains untargeted. This is adding to ds’s anxieties (enc 24-31) ds’s self injurious behaviour has increased again (enc 36)
Dr XXXX and XXXX SALT February 2010 ds was seen for assessment by EP. The report shows a very able boy in all areas. However, Dr X and I felt that this picture does not describe his functional abilities (enc 4)
Another example under social interaction/understanding I have written
Ds has received social skills group 2 x week in school since xxx 2010, this has not been enough. From 2009 to 2011 various external professionals all identify difficulties in this area. I see similar behaviour at home and have not seen any improvement. ds did not achieve xxxx 2010 IEP target (enc 17). This target was removed before it was met. This area remains untargeted. This is adding to ds’s anxieties. Ds’s self injurious behaviour has increased again (enc 36)
