If they want to teach creationism or intelligent design in a religion course, they would have passed their audit. Teaching creationism in a science class is not kosher, since the first base premise of science is that observed events have a natural explanation. If you believe in supernatural explanations, it really isn't science. This is definitional. Now, if they want to exclude teaching evolution from their biology courses, then maybe they could pass the audit also.
It would be similar to teaching New Age ideas about how people get sick in a germ theory or microbiology class.
It sounds to me like they are picking a fight with the accreditation agency. They don't have to have accreditation. There may be some government and military jobs that their graduates would be excluded from, but if it is a matter of principle, then they should stick to their guns.
science is not entirely fact. Much of it is a religion to the atheists.
