This report describes the results of a REL Southeast study comparing student success in online credit recovery and general courses taken online compared to traditional face-to-face courses. Credit recovery occurs when a student fails a course and then retakes the same course to earn high school credit. This research question was motivated by the high use of online learning in the Southeast, particularly as a method to help students engage in credit recovery. The data for this study covered all high school courses taken between 2007/08 and 2010/11 in Florida (excluding Driver's and Physical Education). The study compares the likelihood of a student earning a C or better in an online course as compared to a face-to-face course. Comparisons for both general and online courses include those courses taken for the first time and credit recovery courses. The results show that the likelihood of a student earning a grade of C or better was higher when a course was taken online than when taken face-to-face, both for general courses and credit recovery courses. Most subgroups of students also had higher likelihood of success in online courses compared to face-to-face courses, except that English language learners showed no difference in outcomes when taking credit recovery courses online. However, it is not possible to determine whether these consistent differences in course outcomes are attributable to greater student learning, other factors such as differences in student characteristics, or differences in grading standards. The following are appended: (1) Data and methodology; and (2) Detailed results.
