Similar bills have been vetoed twice before, but Rep. Michael Morley, R-Spanish Fork, said the governor is comfortable with this year's bill.

Supporters say some school officials overstep their duties by pressuring parents to medicate their hyperactive children. Opponents of the bill, including doctors and support group leaders who work with hundreds of families, said they've never heard such stories. Three doctors who addressed the committee worry the bill will chill communication between teachers and parents, which is vital to accurate medical diagnoses. They also point to existing rules that bar teachers from diagnosing medical conditions.

The bill passed on a vote of 4 to 2.

What's next: Bill moves to the Senate floor.
