There's an organization called the National Council on Teacher Quality that creates a lot of attention for itself by promoting a ranking system it's developed for teacher preparation programs. The NCTQ rankings have irked many people in teacher education, generally because the methods and criteria used in the rankings appear flawed, such as judging a university's program by content found in course syllabi. These feelings now appear validated, as Gary Henry and folks at Vanderbilt have done some research of their own and found that NCTQ rankings more or less have no correlation with the average effectiveness of graduates of teacher education programs.
