Done! Dropped the letter off this morning.

I met some other GT parents last week, both their children had this teacher previously and they loved her. They said that she kept trying different interventions throughout the school year (as late as the month that school ended) to improve outcomes. We'll officially meet her on Thursday.

As a side note, their DD, starting 4th grade, seems to be underachieving, so I was able to direct them toward "A Nation Deceived". I'm hoping that the more GT parents are aware of the research, the less I will be "that parent" and the more that everyone will be successful in advocating for our kids. (Then I don't have to be the first person to mention it with a child who is new to the school.)
