Washington offers two homeschool pathways. Most families use the homeschool statute, which requires filing a Declaration of Intent by September 15 each year with your local district. Instruction must cover 180 days OR average 1,000 hours per year (your choice), in occupational education, science, math, language, social studies, history, health, reading, writing, spelling, art, and music appreciation. An annual standardized test or evaluation by a certified person is required, but results are not submitted to any state actor — they're kept by you. The teaching parent must have completed 45 college quarter-credit hours, completed a parent-qualifying course, be supervised by a certified teacher, or be deemed sufficiently qualified by the local district superintendent. The alternative pathway — enrolling under a private school's extension program — shifts compliance to the private school. Compulsory attendance covers ages 8–18. WHO (Washington Homeschool Organization) hosts the statewide convention and is the primary community resource. The annual September cadence becomes routine after the first year.

Public school sports access for homeschool students varies by district in Washington, and the rules are typically set by the state high school athletic association rather than the legislature. Many districts allow participation under state equal-access laws or athletic association rules; others have restrictions tied to part-time enrollment or residency.
Contact your local school district's athletic director directly to confirm what your child can participate in this year, and consult HSLDA's Washington page for the current statewide picture.
