What are the identity verification rules for the Praxis exam?

I have a kind of predicament, and I need some guidance. I am asking whether it is legal or possible to have somebody impersonate me through the take my PRAXIS test for me. I have read both good and bad things online, yet I would like to know the rules in order to think about anything. What are the dangers, and is there any fair method of seeking assistance with the exam without contravening the rules? It would be much appreciated to get some guidance.
