The school board or board of education may authorize the emergency exclusion, short-term or long-term suspension, expulsion, or mandatory reassignment of any pupil from school for conduct prohibited by the board's rules or standards established pursuant to the Student Discipline Act if such emergency exclusion, short-term or long-term suspension, expulsion, or mandatory reassignment complies with the procedures required by the act.

Administrative and teaching personnel may take actions regarding student behavior, other than those specifically provided in the Student Discipline Act, which are reasonably necessary to aid the student, further school purposes, or prevent interference with the educational process. Such actions may include, but need not be limited to, counseling of students, parent conferences, referral to restorative justice practices or services, rearrangement of schedules, requirements that a student remain in school after regular hours to do additional work, restriction of extracurricular activity, or requirements that a student receive counseling, psychological evaluation, or psychiatric evaluation upon the written consent of a parent or guardian to such counseling or evaluation.

(1) The school board or board of education may by rule amplify, supplement, or extend the procedures provided in the Student Discipline Act if such actions are not inconsistent with the act.

(2) Any action taken by the school board or board of education or by its employees or agents in a material violation of the act shall be considered null, void, and of no effect.

(3) The school board or board of education may authorize the delegation to other school officials of responsibilities directed to the principal or superintendent by the act.

(1) The school board or board of education shall establish and promulgate rules and standards concerning student conduct which are reasonably necessary to carry out or to prevent interference with carrying out any educational function, if such rules and standards are clear and definite so as to provide clear notice to the student and his or her parent or guardian as to the conduct prescribed, prohibited, or required under the rules and standards. Notwithstanding any other provisions contained in the Student Discipline Act, the school board or board of education may by rule specify a particular action as a sanction for particular conduct. Any such action must be otherwise authorized by section 79-258, 79-265, or 79-267. Any such rule shall be binding on all students, school officials, board members, and hearing examiners. Expulsion may be specified as a sanction for particular conduct only if the school board or board of education finds that the type of conduct for which expulsion is specified has the potential to seriously affect the health, safety, or welfare of the student, other students, staff members, or any other person or to otherwise seriously interfere with the educational process. On or before August 1 of each year, all school boards shall annually review in collaboration with the county attorney of the county in which the principal office of the school district is located the rules and standards concerning student conduct adopted by the school board and the provisions of section 79-267 to define conduct which the principal or designee is required to report to law enforcement under section 79-293.

(1) Except as provided in section 79-265.01, each school district shall adopt a policy requiring the expulsion from school for a period of not less than one year of any student who is determined to have knowingly and intentionally possessed, used, or transmitted a firearm on school grounds, in a vehicle owned, leased, or contracted by a school being used for a school purpose or in a vehicle being driven for a school purpose by a school employee or his or her designee, or at a school-sponsored activity or athletic event. For purposes of this section, firearm means a firearm as defined in 18 U.S.C. 921. The policy shall authorize the superintendent or the school board or board of education to modify the expulsion requirement on an individual basis.

(3) On or before July 1, 2009, each school district as defined in section 79-101 shall develop and adopt a policy concerning bullying prevention and education for all students.
