OMAHA, Neb. (AP) — Teachers a middle school in Omaha will soon get two days for special disciplinary training to respond to persistent bad behavior at the school.

The Omaha school district is adding more administrators and hired a consultant to help reform procedures at Nathan Hale Magnet Middle School. Teachers at the school have complained this year of widespread discipline problems, including assaults on staff and other students.

Principal Darin Williams says the problems are due to a small group of students.

Parents and staff at a meeting Monday called for higher expectations, more parental involvement and greater diversity among teachers.

The school’s enrollment has nearly doubled this year with the addition of sixth-graders.
