Education: curriculum; requirement for schools to provide instruction on African-American history; provide for, and create the commission to update African-American history in K to 12 instruction. Amends 1976 PA 451 (MCL 380.1 - 380.1852) by adding sec. 1164.

HB 4020 creates a temporary commission to update African-American history curriculum for Michigan K-12 schools. The commission, appointed by the governor and including university representatives, NAACP, and museum staff, must review current standards within 365 days and recommend age-appropriate instruction covering Reconstruction, the Civil Rights Era, and African-American contributions to U.S. development. Starting in the 2026-2027 school year, Michigan school districts must provide this instruction, and state assessments will include related questions. The bill mandates curriculum updates to the state board within two years of the commission's recommendations. This directly affects all public K-12 schools in Michigan and their required social studies curriculum.
