(1) The General Assembly finds: That the current standard, which requires cause that is not arbitrary, capricious, or discriminatory for the nonrenewal, termination, or suspension of a teacher, should be raised to a standard of just and reasonable cause; and
(2) That the current standard for compliance with this subchapter and a school district's personnel policies of strict compliance should be lowered to substantial compliance.
(3) This subchapter is not a teacher tenure law in that it does not confer lifetime appointment of teachers.
(4) A nonrenewal, termination, suspension, or other disciplinary action by a school district shall be void unless the school district substantially complies with all provisions of this subchapter and the school district's applicable personnel policies.
