The presence of religious literature was the source of frustration Wednesday among several Democratic board members and Texans who testified. Still, many of the speakers at Wednesday’s meeting said the list lacked racial, ethnic or gender diversity — pointing out that Hispanic and Black children make up the majority of Texas students. “This list does not represent the students of Texas,” said Tiffany Clark, a Democratic board member who is Black and represents parts of North Texas. Whatever reading list the State Board of Education agrees upon, however, will be mandatory. But the education agency acknowledged Wednesday that students could still be tested on the material.
