Washington RCW 28A.155.220: High School Transition Services
“The office of the superintendent of public instruction must establish interagency agreements with the department of social and health services, the department of services for the blind, and any other state agency that provides high school transition services for special education students. Such interagency agreements shall not interfere with existing individualized education programs, nor override any individualized education program team’s decision-making power. The purpose of the interagency agreements is to foster effective collaboration among the multiple agencies providing transition services for individualized education program-eligible special education students from the beginning of transition planning, as soon as educationally and developmentally appropriate, through age twenty-one, or through high school graduation, whichever occurs first. Interagency agreements are also intended to streamline services and programs, promote efficiencies, and establish a uniform focus on improved outcomes related to self-sufficiency.”
