Going to a TV station wouldn't be on my list of options. That's why she's a pendeja. Saying that she had no idea of this problem shows that she's a pendeja. I don't believe she made any mention that she didn't receive any progress reports or anything of the such. If I was unaware of the problem and I didn't receive any progress reports, much less pay attention to her frickin' report card, then I'd be saying I never received any notification of any problem.
I'd deal with that, first, before I went to any damn TV station and before I dealt with the teacher on what she did.
