Tiffany Clark, who was elected to fill a vacant State Board of Education seat in January, said she would have voted against the curriculum.

The curriculum adopted by the Texas State Board of Education, which is controlled by elected Republicans, is optional for schools to adopt, but they will receive additional funding if they do so. The materials could appear in classroom as early as next school year.

The Texas Board of Education will vote Friday to implement its new K-5 curriculum that calls for expanding Bible teachings in classrooms.
