A judge also sent Hall, who taught at Riverton's Rosamond Elementary School, to prison for 15 years to life.

But Rep. Carl Wimmer, R-Herriman, doesn't think that is enough, so he is sponsoring a bill that would force the Utah State Board of Education to permanently revoke the licenses of teachers who molest students or other children.

Rep. Stephen Sandstrom, R-Orem, also is sponsoring a bill that would allow the the board to revoke a teacher's license for sexually explicit conduct with an adult student. Both bills follow an Associated Press study that showed Utah ranked 16th in the nation for the number of teachers whose licenses were revoked or suspended for sexual misconduct.

"Over the last year some of my constituents have gone through hell because of Frank Laine Hall," Wimmer said. "This may or may not prevent other teachers from committing these offenses, but it will hold them responsible."

The Utah Professional Practices Advisory Commission (UPPAC) sometimes recommends the board revoke teachers' licenses permanently. But often, as in Hall's case, UPPAC recommends the board revoke teachers' licenses for five or more years. After that time, if the teachers can prove at a hearing they have completed counseling and met other conditions, they might technically be able to regain their licenses.

UPPAC investigator and prosecutor Jean Hill said she has never heard of that happening in serious cases. "We've never reinstated someone who's been sexually involved with a student, and they don't come back to get [their licenses]."

Still, Wimmer wants to make sure of that. If a teacher violates parents' trust, "I don't want them to ever have that opportunity again," he said.

Cal Evans, Jordan School District executive director for compliance, supports Wimmer's bill, saying it is important to keep child predators away from schools.

Hill, however, has concerns about the legality of permanently revoking teachers' licenses without criminal convictions. Wimmer's bill would revoke teachers' licenses based on UPPAC findings.

"A permanent revocation is a very serious action, and it may not fit every situation," she said.

Hill said UPPAC's rules already give it power to revoke licenses of teachers who have relationships with adult students, as Sandstrom's bill would do. Sandstrom said he wanted to make sure the rule made it into state law as well.
