Rather than award credit for an introductory course to incoming students who got the highest score on the AP test, the department gave those students a condensed version of the Dartmouth course's final exam. Ninety percent failed, Tell said. And when those students went on to take the introductory class, they performed no better than those who did not have the high AP test scores.

I was surprised at the number of fellow students at my University who openly admitted that within a month or two of the final exam, they couldn't recall much of anything about some of the courses in which they had scored an A or higher in.
It's entirely possible that the issue isn't the AP courses, but the significant delay taking (and doing well in the course) - and retesting again.
Alternatively - take a student from another Ivy League, Yale, Harvard - and see how they would do on a Dartmouth Final exam with some delay between taking the course and testing out again.
I think it is related to a similar effect I have noticed- when I teach something, I again retain that information much better.
Like most standardized tests, the AP tests are incredibly game-able. As a student, I began taking random AP tests without taking the class and just studying a guide the week before the test. I passed every test (most with a 5), but that was because I had learned to become good at the test, rather than learning the material behind it. (There are some exceptions, like art portfolios)
But myself and the above commenter (InclinedPlane) are the exception. There is, frankly, no better way for a student to demonstrate prior knowledge of a subject than through a standardized test.
Dartmouth, and all colleges, are welcome to set their policies to reflect their trust in the system, but there should be a way, whether internal or standardized, for a student to be placed based on prior knowledge.
I'm not sure this supports your conclusion. My guess is that many of us could do the same for the final exams of the classes those AP tests translate to credit for. In fact I'd guess most of us either did this or know of many people who did the same for even more advanced classes.
I'm really curious whether Dartmouth performed any studies on the matter or if this is just a spontaneous decision based on anecdotal evidence.
P.S. Also, in my experience and observation taking 100 and 200 level classes in college is a pretty significant ripoff outside of perhaps the top 20 universities in the nation. Almost all of the time such courses tend to be taught by assistants and are heavily textbook based. For the vast majority of people pursuing a college education getting an AA at a community college and then transferring to a local state college is a far, far better option financially.
