Florida’s education department has rejected 54 mathematics textbooks from next year’s school curriculum, citing alleged references to critical race theory among a range of reasoning for some of the rejections, officials announced.

The department said in a news release Friday that some of the books had been rejected for failure to comply with the state’s content standards, Benchmarks for Excellent Student Thinking [Best], but that 21% of the books were disallowed “because they incorporate prohibited topics or unsolicited strategies, including CRT”.

The release does not list the titles of the books or provide any extracts to offer reasons why the books were removed.
