Student Sues Nevada College, Claiming Sex Class Assignments Equaled Harassment

After reviewing the college's own investigation, the Office of Civil Rights wrote in a Jan. 25, 2012, letter that it deferred to the college's decision and would not be pursuing the allegations any further, Hansen said.

Undeterred, Royce filed her federal suit. McKenna said it could take up to a year for the case to reach a court room, but he hopes the school will terminate Kubistant.

"I think he needs to be terminated. He has crossed so many ethical, legal and moral boundaries," McKenna said. "My mind immediately went to the question is he grooming these young 17-, 18-, 19-year-olds so he can have further contact with them outside the school environment? His behavior borders on perversion."

Royce is continuing to pursue her education, but McKenna said her experience in the human sexuality class was a "setback."

"It was a shocking experience and altered her perception of current education," he said. "She still is shocked by the fact the school is willing to accept this kind of behavior."

Kubistant did not ABCNews.com's request for comment. He is still teaching at the college.
