The Texas State Teachers Association is calling the delay in updating the social studies curriculum an “extremist attack on history curriculum” and an “attack on teachers.”

The Texas State Board of Education sets curriculum standards for Texas public schools, and its makeup will change after Tuesday's election. But Republicans appeared poised to keep control of two other seats Texas Democrats wanted to flip this year. Currently, the 15-member education board seats 10 Republicans and five Democrats — with eight seats in play this year. Popp also picked up the support of Texas Values, a conservative statewide advocacy group, which recently urged the board to adopt abstinence-focused sex education. The board is weeks away from revising Texas' sex education policy, its first attempt to do so since 1997.
