Alabama Governor Kay Ivey signed into law on Wednesday a ban on diversity, equity and inclusion programs in public schools, making the state one of a few to enact broad measures against what she and other Republicans call a leftward tilt in U.S. education.

The bill, which passed Alabama’s Republican-led legislature on Tuesday, bans public schools from maintaining diversity, equity and inclusion offices or teaching what the bill calls “divisive concepts” about race and identity, such as that of holding people of one race responsible for actions committed by the same racial group in the past.

It also requires public institutions of higher education to designate bathrooms as only for males or females, a move that counters transgender rights advocates’ push for gender-neutral bathrooms.
