The Vallivue School District Board of Trustees accepted Lisa Carriere's resignation without discussion at the board's Tuesday meeting, Superintendent Pat Charlton told KIVI-TV, Channel 6.
Carriere, 47, faces a misdemeanor charge and a threatened lawsuit for allegedly slapping a nonverbal 6-year-old with autism on Jan. 5 at West Canyon Elementary School in Caldwell.
The boy's family filed a tort claim seeking $2500 in damages. The claim states the child had a red hand-shaped mark on his face as well as swelling, a loosened tooth and an abrasion inside of his mouth.
Carriere is scheduled for a pre-trial hearing on the injury to a child charge on March 30.
