Source: Restricted use database covering placement test takers at the LUCCS community colleges.
Notes: All outcomes measured three years after test date unless otherwise noted. Outcomes for college-level math include zeros for those who never took college-level math. Equated credits are a measure of total credits which include remedial coursework. Estimates of effects on exit exam scores are not strictly causal because they are computed only for those students (representing approximately 17 percent of the analysis sample) who took the exam; however, because there is no impact on taking the exam, this limits the concern that such comparisons are biased by differential selection.
