Several things must be done here:

1. What makes the claims of TX against CCU valid? The state of TX must prove these claims against CCU, or "back-off" from their claims and issue necessary apologies for defaming the school, its students and misleading the public.

2. To undermine a school is one thing, but to undermine the DETC which is a respectable accrediting body recognized by the U.S. Department of Education is another thing. The DOE & DETC "must take immediate action" to protect institutions under their span of accreditation.

3. Labeling an accredited institution "fraudulent" or a "diploma mill" is a serious charge. CCU must defend it's honor by legally challenging the state of TX in this situation - to protect both its reputation and student body from these damaging claims of fraud.

I hope to see a positive outcome from all of this, since a state cannot define and impose its own set of educational standards which totally oppose the set standards defined by the U.S. Government and its agencies.
