Every principal or teacher in charge of a public school may temporarily suspend any pupil on account of disobedience or misconduct, and any principal or teacher suspending any pupil shall promptly notify the district superintendent or secretary of the board of school directors. The board may, after a proper hearing, suspend such child for such time as it may determine, or may permanently expel him. Such hearings, suspension, or expulsion may be delegated to a duly authorized committee of the board, or to a duly qualified hearing examiner, who need not be a member of the board, but whose adjudication must be approved by the board.
