According to a statement from the two groups, the new Kansas standards are improved, but as currently written, they overemphasize controversy in the theory of evolution and distort the definition of science. NAS and NSTA offered to work with the board to resolve these issues so the state standards could use text from the National Research Council's "National Science Education Standards" and NSTA's "Pathways to Science Standards."
This is not new either. NAS and NSTA refused Kansas their permission in 1999 too.
