I found this on my NYC schools website. Strictly copied, I have no knowledge on the subject:
200 mathematicians, including several Nobel laureates, have written to the US Department of Education complaining about reform mathematics. The chairmen of almost every college and university mathematics department in the New York area have written to Klein complaining that the reform programs like TERC and Everyday Mathematics are failing to educate our kids in math so that they can do college work.
The rubber stamp committee that "advised" Klein and Diana Lam (remember her?) on Everday Mathematics did not include anyone with a degree in math or engineering, nor anyone even qualified to teach high school math. Actually, Everyday Mathematics for our kids was the brainchild of the discredited Lam.
TERC and Everyday Mathematics lead students directly to math remediation classes as they enter college. Those classes are bigger than ever since the introduction of NCTM reform math programs. The decline of American mathematics education compared with the rest of the world is directly traceable to these reform programs.
These are the reasons that TERC and Everyday Mathematics are no longer permitted in the public schools of California which now leads the nation in Math education.
