How many hours of homeschool instruction are required in Wisconsin?

Wisconsin doesn't mandate a specific number of hours of homeschool instruction. Instead, it requires that homeschool students complete a "full-year program of instruction" in the subjects required by law. The law doesn't define "full-year" in terms of hours. The determination of sufficient instruction is left to the homeschooling parent's judgment, subject to the requirement to meet the state's other regulations regarding curriculum and assessments.
