A lot of big universities have research schools where they test schooling techniques on students, run assessments and see what works. The problem is most of these schools are near big universities. So you've got an overwhelming amount of students who are nurtured in an education rich environment (mama is a professor, papa is an adjunct, etc.), they are well ahead of the rest of the country as far as educational experiences. Then when they run the tests and think they have a success, it usually results in failure once they try to roll it out to schools in a completely different environment. What they should be doing is working on the baseline students, inner city schools, poor areas. But this requires professors to get out their comfort zones and they don't want to do that. A lot of these research schools are very competitive. They'll basically ace any test you put in front of them just because they can.
