(1) Each school district must adopt a harassment, intimidation, and bullying prevention policy and procedure as provided for in RCW 28A.300.285.

(2) If the allegations in a written report of harassment, intimidation, or bullying pursued under the school district's procedure adopted under RCW 28A.300.285 indicate a potential violation of this chapter or the guidelines adopted under WAC 392-190-005, the school district's harassment, intimidation, and bullying compliance officer, designated under RCW 28A.300.285, must promptly notify the district employee designated under WAC 392-190-060. Or, if during the course of an investigation of harassment, intimidation, or bullying, the district becomes aware of a potential violation of this chapter or the guidelines adopted under WAC 392-190-005, the school district staff member investigating the report must promptly notify the district employee designated under WAC 392-190-060. Upon receipt of this information, the designated employee must notify the complainant that their complaint will also proceed under the discrimination complaint procedure in WAC 392-190-065 through 392-190-075, in addition to the procedures adopted under RCW 28A.300.285. School districts must provide this notice in a language that the complainant can understand, which may require language assistance for complainants with limited-English proficiency, in accordance with Title VI of the Civil Rights Act of 1964. In these cases, the investigation and response timeline set forth in WAC 392-190-065 begins when the school district knows or should have known that a written report of harassment, intimidation, or bullying involves allegations that the school district has violated this chapter or the guidelines adopted under WAC 392-190-005.

(3) This section is not intended to limit the scope of RCW 28A.300.285 or the use of a school district's procedures adopted under RCW 28A.300.285.
