Veiled,

Don't try to do this alone; you will not win. That's what the school board is counting on.

Get the media involved; schools and school systems don't like negative publicity because too often more people step forward with stories of the same.

Get the therapist involved. With a letter from the doctor, the absences will have to be excused, especially with anxiety and depression. There is a known condition called "school anxiety" that is just that: anxiety about going to school. The school cannot ignore it; they will get into huge trouble if they do. And, get the therapist to insist on a home teacher, one that will go to your house (or some other place agreed upon by every one) that will teach her the lessons she will miss by not being in school.

Get a lawyer involved. Just the threat of a lawsuit should wake the school system up. If it doesn't, don't back down. Sexual harassment is a real thing and too often in schools is it underreported for a variety of reasons, not the least of which is adults not believing or taking it seriously.

The comment of "it should've been reported Friday" is just a tactic to scare you off; don't back down. There is no statue of limitations in the country for sexual offenses and the same holds true for schools (they are not above and beyond the law).

Call the school and make an appointment to see the principal (if you haven't already). Popping in to the school often doesn't get results we wish for; the principal has meetings, conferences, observations, etc. already planned (parents where I work aren't allowed to just "pop in" for conferences with teachers either because we are so busy with grading, planning, meetings, etc.).

But don't go alone; take your lawyer (if you already have one). That way nothing is agreed upon that could be used against you later.

Then begin up the chain of command.

Good luck, Veiled...we're here for you!
