Hey Tony, as you know I used to live in Oklahoma and know the system well. First, be calm, and proceed with offering suggestions as you have done, but be firm. A little known fact is that I was loosely involved when everything went down at Owasso and for those in Oklahoma all you should have to do is remind the principal or any others of Owasso and their issues related to Title IX.
Be firm, in being firm you may also have to seek legal council for a situation like this. I would speak to the school board or superintendent first. It is always better to make friends than to make enemies. It is also better to stand up for your daughter over school systems. If need be, you would be able to find an attorney easily for this.
I am curious as to the school system you are at. I have my suspicions and if I am correct, it is time that system has an issue like this addressed. Email me off line and I can give you further information and details as to everything that went down at Owasso.
