National survey of colleges of education deeply flawed, incomplete

Imagine a new restaurant comes into town. Its goal is to lure away customers who visit existing restaurants in the community. To achieve this goal, they gather the menus of each restaurant. Based nearly exclusively on these menus, they develop a rating scale critical of each restaurant, which is subsequently published in the local newspaper. The casual reader of this newspaper might be swayed by the rating scale and wonder what's occurring in those restaurants. The critical reader would speculate about the motives of the new restaurant, would question the use of the menu as the nearly exclusive source of the ratings, would wonder why the food wasn't tasted or former customers interviewed, and would marvel that any newspaper would even publish these restaurant ratings.
