New data and analysis from the National Council on Teacher Quality finds significant progress on the science of reading instruction in teacher preparation. For the first time since NCTQ began publishing program ratings in its 2013 Teacher Prep Review, the number of programs in the nation to embrace reading science has crossed the halfway mark, with 51 percent of 1,000 evaluated traditional elementary teacher preparation programs across the country now earning an A or B grade for their coverage of the key components of the science of reading--up from just 35 percent seven years ago.
