The school board on Tuesday is scheduled to consider the ban, which is supported by the school superintendent.
Currently, students can be suspended for refusing to remove a hat or cursing the teacher.
The Los Angeles Times ( http://lat.ms/18EpJ5e) says willful defiance suspensions accounted for nearly half of all California suspensions in the 2011-2012 school year. Black students were disproportionately affected.
Critics say it's a catch-all way of getting rid of underachievers that hurts the student but does nothing to solve behavior issues.
Supporters say defiant kids disrupt classes and reduce learning time. Gov. Jerry Brown vetoed a bill last year that would have barred suspensions for defiance.
