RCW 28B.15.544
Findings-Intent-1999 c 344: "The legislature finds that policies that encourage regional planning and access to higher education benefit both the students and the state. Such policies improve access, reduce unnecessary duplication, and make higher education more cost-effective. The western undergraduate exchange program, coordinated by the western interstate commission for higher education is a program through which students in participating states may enroll in designated institutions in other participating states at a special, reduced tuition level. During the 1998-99 school year institutions in fifteen western states participated in the western undergraduate exchange program, including Washington's bordering states of Oregon and Idaho. Eastern Washington University participated on a pilot basis. It is the intent of the legislature to permit Washington's institutions of higher education to participate in the western undergraduate exchange program." [ 1999 c 344 s 1.]
