Yeah. I had this ALL year. One parent insisted her daughter was failing because I was YOUNG. She would first call me, then she switched to guidance and finally would just call my AP. She was the only parent who gave me a problem and blamed me for their child failing. Meanwhile, the girl would cut mandatory tutoring & my class. Besides the fact that the mom never came up to see me for parent teacher night. All the other parents were very supportive that I was a young teacher (23yo).
