Washington State Legislature's Revised Code of Washington (RCW) 28A.320.260

Dyslexia interventions

1. Beginning in the 2021-22 school year, and as provided in this section, each school district must use multitiered systems of support to provide interventions to students in kindergarten through second grade who display indications of, or areas of weakness associated with dyslexia. In order to provide school districts with the opportunity to intervene before a student's performance falls significantly below grade level, school districts must screen students in kindergarten through second grade for indications of, or areas associated with, dyslexia as provided in this section.
2. Screening Tools
   1. School districts must use screening tools and resources that exemplify best practices, as described under RCW 28A.300.700.
   2. School districts may use the screening tools and resources identified by the superintendent of public instruction in accordance with RCW 28A.300.700.
3. Interventions
   1. If a student shows indications of below grade level literacy development or indications of or areas of weakness associated with dyslexia, the school district must provide interventions using evidence-based multitiered systems of support, consistent with the recommendations of the dyslexia advisory council under RCW 28A.300.710 and as required under this subsection (3).
   2. The interventions must be evidence-based multisensory structured literacy interventions and must be provided by an educator trained in instructional methods specifically targeting students' areas of weakness.
   3. Whenever possible, a school district must begin by providing student supports in the general education classroom. If screening tools and resources indicate that, after receiving the initial tier of student support, a student requires interventions, the school district may provide the interventions in either the general education classroom or a learning assistance program setting. If after receiving interventions, further screening tools and resources indicate that a student continues to have indications of or areas of weakness associated with dyslexia, the school district must recommend to the student's parents and family that the student be evaluated for dyslexia or a specific learning disability.
4. For a student who shows indications of, or areas of weakness associated with dyslexia, each school district must notify the student's parents and family of the identified indicators and areas of weakness, as well as the plan for using multitiered systems of support to provide supports and interventions. The initial notice must also include information relating to dyslexia and resources for parental support developed by the superintendent of public instruction. The school district must regularly update the student's parents and family of the student's progress.
5. School districts may use state funds provided under chapter 28A.165 RCW to meet the requirements of this section.
