I'm sorry I can't point you to a public online source. My comment is anecdotal; relying on my own observations across family and friends with kids at the HS level. It is pretty obvious speaking to them that their advisors and administrators expect all written pieces to comply with DEI principles. I have asked if there is a formal style-book and no one has pointed me to one yet. But there is a powerful group think. Not complying is asking for censure or excommunication.
There's a sign in the assistant principles offices at my local high school which defines what critical race theory is, including the "critique of liberalism" part.
I would ban public high schools from encouraging a "critique of liberalism". Being a critic takes no skill and doesn't help the world. Critical theory, and critical thinking are extremely overrated skills. We need constructive thinking and constructive communication.
It is not in fact the case that you can work out what Critical Theory, Critical Legal Theory, and Critical Race Theory (3 distinct concepts originating at 3 different points in the 20th century) axiomatically from the the word "critic".
