In the 2011 legislative session, House Bill 3681 written as, "Allows student to attend school in school district where student does not have legal residence if student receives written consent from district where school is located." was introduced to and passed the Oregon House, passed the Oregon Senate and was signed into law.

According to the Oregon Department of Education website:
Open Enrollment, enacted by the Oregon Legislature in 2011, created an additional option for students wishing to transfer between districts. The open enrollment statute contains a sunset provision, effective July 1, 2019.
What this means for districts and students:
The Legislature may choose to extend the sunset during the 2019 legislative session. However, until the Legislature takes action, the sunset is still in effect and districts may not enroll new students through open enrollment.
