[senco-forum] advice early literacy

I have a year 4 child, P levels, relative visual strengths. general  
cognitive ability 1%, arrived with 3 initial letter sounds, no sight  
vocab, unable to copy handwriting patterns,
I have used multi sensory techniques, lots of over learning, blood  
sweat etc and  now he:
knows all letter sounds
about 30 Reception sight vocab
can form some letters correctly
can spell a few words
likes to 'read' Jelly and Bean books
not much success with word building

Long story, but today I have been made to feel by county that I have  
failed this child and that he should have achieved much more,   
(Everyone who meets this child says not mainstream - EP, us, mld  
outreach, even ofsted!)

So, what 'magic programme' would you advise, please?
thanks
Sue
