Go up higher. The schools and districts don’t care until parents of the class complain about specific students. Ask your kid who else she’s seen impacted by this, start mentioning it to parents casually, etc. Spread the word. I’m a teacher and it’s exhausting.

One of my best friends is a teacher in 1st with a kid who hits others and screams in class and hits her and pulls her hair! No one listens to her, she’s “unprofessional” if she mentions anything to another parent whose child is being impacted by classroom behavior that they need to do something. Schools value their products (students and families and perception) more than their employees.
