In the summer of 2013, the National Council on Teacher Quality (NCTQ) issued public, highly-visible ratings of teacher education programs as part of their ambitious and controversial Teacher Prep Review.

Test-score ceilings are increasingly common in testing instruments across the country as education policy continues to…
