“…More intense early enrollment is associated with improved degree completion at two- and four-year colleges, especially among minority students (Attewell, Heil, and Reisel, 2012 ; Attewell and Monaghan, 2016 ). These effects also apply to grades (Brugiavini et al 2020 ), and effects may be stronger if intensity is maintained (Belfield et al 2016 ). Volkwein and Lorang ( 1996 ), Knight ( 2004 ), Belfield et al ( 2016 ), and Venit ( 2017 ) all find direct or indirect evidence that increase course load reduces completion time, although Cornwell, Lee, and Mustard ( 2005 ) find only mixed evidence.…”
