Education: athletics; children who are homeschooled or attending nonpublic school; require the board of a school district or intermediate school district to allow to participate in certain extracurricular activities. Amends 1976 PA 451 (MCL 380.1 - 380.1852) by adding sec. 1290.

HB 4856 requires Michigan public school districts and intermediate school districts to allow homeschooled or nonpublic school students to participate in extracurricular activities like sports teams, theater, band, and debate. It prohibits school boards from blocking these students' participation and mandates that districts avoid joining athletic conferences or associations with exclusionary policies. The bill defines an "eligible child" as one residing within the district, homeschooled or attending a nonpublic school, and meeting standard eligibility requirements. This directly affects homeschooled and nonpublic school students seeking access to school-run activities. The law amends the Revised School Code (MCL 380.1 et seq.) by adding Section 1290.
