School curriculum; require comprehensive MS History course for public school students in Grade 9.

HB 462 requires all public school students in Mississippi Grade 9 to take a comprehensive Mississippi History course beginning July 1, 2025. The course must cover Mississippi's history from colonial times to the present, with specific emphasis on 19th- and 20th-century political, social, economic, and cultural issues affecting the state's diverse racial and ethnic populations. This policy directly affects all public high school freshmen in Mississippi by mandating a new curriculum requirement. The bill does not specify teaching methods or materials, only the scope and timing of the required instruction.
