My DS got something like that on his report card at the end of the year last year. It said something like "even though X is gifted and talented, he has to learn that he has to follow the rules just like everyone else." The teacher never even spoke with us during the 1/2 year he was in the class about any behavior issue and we were a large presence at the school. Plus it was a mid year skip so he was the youngest in the class.
I wrote the teacher a scathing email something along the lines of she needed to learn (even though she was not gifted and talented) to engage her students and that it was her responsibility to teach kids "the rules" and that maybe if she used some other behavior system other than public humiliation he would have "learned" something in her class.
Then . . . I sent the email to my husband.
