Relating to social studies curriculum choice for public school students.

HB 178 requires Texas public school districts to include "ethnic studies, world geography, or world history" as one of the three required social studies credits for high school students, alongside existing mandates for U.S. history, government, and economics. It directly affects all Texas public school students in grades K-12 by modifying the social studies curriculum structure under the foundation high school program. The bill adds ethnic studies as a specific, mandatory option for fulfilling the social studies credit requirement, while maintaining other existing subject requirements. This change applies to all Texas public school districts offering grades K-12.
