Establishing a public school-based mental health internship grant program.

SB 5666 creates a grant program to address Washington's shortage of school psychologists by funding full-time school psychology interns in public schools. School districts, charter schools, and tribal education schools can apply for grants covering 75% of interns' entry-level salaries, provided interns are enrolled in accredited programs and placed with qualified supervisors. The program aims to increase the pipeline of school psychologists by supporting internships, which research shows improves retention after three years of employment. It requires annual reporting on grant recipients, demographic data, and program outcomes starting in 2026.
