Civil right violation related to ferpa?
1 attorney answer
I don't understand what your underlying concern is. If I can try to fill in the blanks, I'm guessing that your son gave the professor an excuse for something, and after investigating that, the professor believes that your son is lying to him. I certainly don't see a FERPA violation here. FERPA applies to a student's private academic record -- nothing here is related to your son's academic record.
If your son has gotten in trouble for whatever this is, he needs to work within the school's administrative system to defend himself. There is probably some process for responding to academic violations. Your son needs to review the student handbook and then follow through.
Be aware that this response does not create an attorney/client relationship. I live and work in Massachusetts and may or may not know the local laws where you live. I hope people find my responses not only helpful but somewhat entertaining as well. If you rely on this as legal advice, remember the old saying, "You get what you pay for."
