A St. Louis high school student is getting an "A" from authorities after discovering a teacher's X-rated past.
Tera Myers, 38, was put on administrative leave at Parkway North High School this week after a student inquired about pornographic films Myers starred in during the 1990s.
The science teacher decided to leave the school "out of respect for her privacy and that of her family," Paul Tandy, spokesman for the school district told the Daily News. "She was concerned about the impact it would have in the building."
Officials didn't know about Myers' past, which included a suspension five years ago from a Paducah, Ky., school for her role in the adult films.
While in Kentucky, Myers taught under a different name, Tericka Dye.
In 2006, the former porn star spoke to several media outlets and even made an appearance on "Dr. Phil," arguing she deserved to get her job back and that she had made the biggest mistake of her life.

"Anybody who has been in my classroom could tell you how much I love teaching and how much I love these students, and that should be what matters more than anything in my past," she said in May 2006.
Myers, whose stage name is Rikki Andersin, said she made the movies when she was living in California, working as an exotic dancer to earn desperately needed cash.

Because Myers' role in the adult films wasn't illegal, her pornographic past didn't show up during a background check.

The teacher, who has been at the school for four years, will be paid through the end of the school year but will not be returning in the fall.
"We're surprised, very surprised," said Tandy. "At the same time we feel for her and her family. We do believe she has tried to move on with her life... Unfortunately, even though it happened 15 years ago, [the video] is still there."
