I wish the article linked to the actual lawsuit. The details matter a lot.
The way I land on this is that actively concealing information about a student from a parent is probably a legit critique. There's hints in the articles that this isn't the case. The teacher set-up a sit-down with the parent to discuss the matter, so at least by that point there was transparency.
Do teachers have an affirmative duty to narc on students to their parents for non-disciplinary issues? Do they have a duty to out queer kids to their parents? I would think not.
Do students need parental consent to join a school club in California?
I think the assertion here is that the teachers saw a kid who, presumable, displayed some sort of behavioral pattern and then either suggested a diagnosis and/or suggested participation in a group where there were social rewards for having a particular condition. (Recruiting a specific student to a group rather than just making it available and known in general.)
The problem is that teachers are not doctors and they are not psychologists. That's why teachers can't diagnose ADHD. But they can submit their suspicions to the school counselor who can suggest evaluation to the parents.
But it gets fuzzy because suggesting their child be evaluated for an identity disorder may get a different response from parents than a suggestion to evaluate for ADHD or another learning impairment.
At what point does a teacher step across the limits of their qualifications? And how do you get kids help with issues where the parents may react badly?
This particular case, as written doesn't sound like the parent freaked out. It sounds like she went along with it and then the child, when out of the school environment for a while due to covid, reverted back on her own. That's written from the parent's perspective. It appears that the lawsuit did not appear until after the student went back to her original gender.
