"[T]he CCRC found that the single strongest predictor of student success that's actually under the college's control -- so I'm ignoring gender and income of student, since we take all comers -- is length of sequence. The shorter the sequence, the better they do. The worst thing you can do, from a student success perspective, is to address perceived student deficits by adding more layers of remediation. If anything, you need to prune levels. Each new level provides a new 'exit point' -- the goal should be to minimize the exit points."
