Community colleges wasting student time and money

Jay Matthews:

As I learn more about community colleges, one of the most surprising lessons has been the sloppy and deceptive ways that students are introduced to courses. Placement tests are not well explained to students. Whether you have a passing score or not can depend on which college you attend.
At least as unsettling are studies showing that dual enrollment courses — community college courses given to high school students — often bar applicants who have less than a B average or fail a placement test, even though they need that taste of college-level work to prepare for the real thing.
Now a troubling new research paper says that the remedial courses given to community college students who do not score high enough on placement tests often do no good. Colleges still swear by the courses, however. Students are further deceived by upbeat guidance to a community college placement test owned by the College Board that tells students, wrongly, that they can’t really fail a placement test.
