Mental health services in public schools

Just had a conversation with my co-worker. Her 11 years old niece tried to commit suicide. Parents blamed the school for not recognizing the problems and tested her before it gets this bad. I just shook my head with the parents completely not taking the responsibility. The kid is already at the special ed class, there is no “lower level” or “more specialized class” at this school, no reason for the school to just randomly “test” the kid, and test for what? They already knew she has issues therefore she is in the special class. She had some incidents and the parents were notified and discussions happened, the parents didn’t take the next steps but yet they expected the school to. Sure everyone missed the sign, but the sign were there. There is only so much a school can do. People need to take responsibility for their own kids.
