(b) Instructional materials, including, but not limited to, materials adopted by the state board or any governing body, shall be factually accurate and reflect the adopted curriculum and standards as described in subdivision (c) of Section 60200, and be consistent with accepted standards of professional responsibility, rather than advocacy, personal opinion, bias, or partisanship.
