DS (summer born) did not meet the expected standard in writing at EYFS. This came as somewhat of a surprise as there had been no mention of any concern throughout the year (we raised concerns with regards to phonics but we're made to feel like these concerns were unfounded). I'm still unsure why he didn't meet the standard, although suspect it may be because he often likes to write random letters down and pretend they mean something/ask you what it says as if it should mean something! 
So as not to drip feed, he has had glue ear since he was a baby and had his second set of grommets fitted in the latter part of his reception year I think his hearing may be a big factor with his writing. There is also a strong family history of dyslexia (which obviously is a concern but too early to tell) and dysgraphia and dyspraxia, although his actual handwriting doesn't seem too bad to me given that he is only just 5.
What support should he be getting in Year 1 to help him meet the expected standard?
