If teachers and other school staff members would just accept that it is okay to be wrong a lot more kids would get the help they need at the time they need it; not years later. It is okay to not know everything.
As a parent I didn't know anything about my child's disability until I had to learn. Trust that I have spent more hours than you researching this disability. I now know what works and what doesn't work so believe me when I tell these things.
