Requires school districts and charter schools to display the Ten Commandments in every building and classroom under their jurisdiction

SB 643 requires Missouri public school districts and charter schools to display the full text of the Ten Commandments in every classroom and school building by January 1, 2026. The display must be at least 11x14 inches, feature the text as the central focus in a large, readable font, and may be a poster or framed document. Schools may use existing funds or accept donated displays but are not required to spend money on them. This bill directly affects all Missouri public and charter schools, mandating the physical display of the religious text in educational settings without specifying how it must be presented beyond size and readability.
