A very good letter, long but warrants attention. I have my kid privately tested due to thestypes of problems and more with the school screeners. The school will not use them for placement but at leasy we know and I submit them and ask for explanations when there is a discrepency between their screeners and a full WISC or Stanford.
I would have a couple bullets that highlight the main problem and highlaight what you are asking them to do at the end. Our admin. have a difficult time reading anything longerthan a half page. sad but true
