Nationally, about 6,000 of the 3.5 million public school teachers face adverse actions against their licenses every year, according to the National Association of State Directors of Teacher Education and Certification (NASDTEC).
Those actions can range from breaking school policy and not paying child support to making an inappropriate comment.
Bella Hoffman was 16 years old when she said her teacher began grooming her.
By the time she turned 17, the abuse had become sexual. Her former teacher, Andrew Snead is now serving an 8-year sentence for sex crimes against students in Powhatan.

"He started manipulating me when I was 16," Hoffman said.
Hoffman says looking back, it was a nightmare.
"Almost immediately after I turned 17 is when he came after me sexually," Hoffman said.
Her case is among a rare but troubling category: teachers who lose their licenses due to bad behavior.

Our investigative team also uncovered cases that did not result in criminal charges but still led to license revocations.

Jimmy Adams, executive director of NASDTEC, said the organization runs a clearinghouse that districts across the country use to check whether a teacher has had issues at other schools.

"Unfortunately, when there are some people who do things that are inappropriate or they violate their professional code of ethics, they tend to overshadow the good work that's really taking place," Adams said.
Adams said some teacher behavior may not rise to the level of a criminal charge but is still deemed inappropriate under school policies. He said access to the clearinghouse helps districts make better hiring decisions.
"It really helps that school district make an informed decision about the people they are hiring, and it also helps them to communicate to their community that they are doing things above and beyond doing their due diligence to try to make sure they're hiring the right people," Adams said.
For Hoffman, knowing those guardrails exist offers some comfort. She has advice for students and parents.
"You have to watch out for everybody, and it's not that you can't trust anyone, but you just have to be careful of who you do trust and put your trust into," Hoffman said.
