# Texas social studies curriculum controversy > Live situation record from CLSTR: https://clstr.news/situations/texas-social-studies-curriculum-controversy > Updated: 2026-09-17T07:17:29.000Z. Sources: 14. Developments: 2. The Texas State Board of Education approved revised high school social studies standards for U.S. history, government, and world geography. The new curriculum, set to take effect in 2030, includes requirements to teach that the September 11 terrorist attacks were motivated by “radical Islam” and to study early Islamic history through the lens of “brutal military campaigns,” the “normalization of slavery,” and the use of “harem slaves.” The decision has faced criticism from curriculum experts, students, and civil rights groups who argue the standards lack historical scrutiny and present Islam through a disproportionately negative lens. Critics specifically noted that the phrasing regarding the 9/11 attacks fails to identify al-Qaida and that the curriculum lacks sufficient context regarding Muslim contributions to fields such as astronomy and algebra. In response to the approval, Muslim community leaders in Houston have initiated a voter registration drive. The Islamic Society of Greater Houston reported efforts to register approximately 1,000 voters weekly at local mosques to increase community participation in state and local elections. ## Timeline ### 2026-09-17: Texas approves controversial social studies standards Texas has approved new high school social studies standards that critics claim contain anti-Muslim bias, prompting Houston Muslim leaders to launch a major voter registration drive. 2 sources. https://clstr.news/cluster/texas-approves-controversial-social-studies-standards ### 2026-09-08: Texas Board of Education approves controversial social studies curriculum The Texas State Board of Education approved new high school social studies curriculum linking the September 11 attacks to “radical Islam” and including controversial descriptions of early Islamic history. 12 sources. https://clstr.news/cluster/texas-board-of-education-approves-controversial-social-studies-curriculum-1 --- Cite as: Texas social studies curriculum controversy.
