The Nebraska State Board of Education has suspended the certificates of two teachers who tried to hide how a student with a peanut allergy tasted a peanut butter sandwich.

Board spokeswoman Betty Van Deventer says the board decided on Tuesday to suspend the certificates of Keri Watkins and Ann Gigstad for a year. The suspensions were dated back to late April last year, when the two resigned from the Millard school district. Thus, Van Deventer says, the teachers’ suspensions have been completed.

The teachers had lied to administrators and the mother of the boy who’d tasted a peanut butter sandwich in Watkins’ classroom earlier in April 2012.
