Oregon
In Oregon, public school K–12 registration is overseen by individual school districts, with enrollment generally opening in the spring or early summer before the academic year begins. Parents or guardians must provide key documentation such as proof of age (typically a birth certificate), immunization records, and proof of residency within the school district. Children entering kindergarten must be five years old on or before September 1 of the school year. Many Oregon districts support online registration platforms, although some may require in-person enrollment or verification. For students transferring from another school, prior academic records may also be required. Since policies and timelines can vary, families are encouraged to contact their local district or visit the district’s website for detailed registration procedures and deadlines.

Washington
In Washington state, public school K–12 registration is handled by each local school district, with most districts opening enrollment in the spring for the upcoming school year. To register, families must typically provide documentation such as proof of the child’s age (usually a birth certificate), immunization records, and proof of residency within the school district boundaries. Children must be five years old by August 31 to enroll in kindergarten. Many districts offer convenient online registration systems, while others may require or offer in-person options. Students transferring from other schools will usually need to submit transcripts or academic records as well. Because requirements and procedures can differ by district, it is important for families to check with their local district office or website for accurate and up-to-date enrollment information.
