Course completion rate

The share of students who enroll in a course and finish it, a core measure of engagement in online and adult learning.

Also called: completion rate

Course completion rate is the percentage of students who enroll in a course and go on to finish it, typically defined as completing all required assignments, passing a final assessment, or reaching the last module. It is one of the most commonly cited metrics in online and adult learning, particularly for massive open online courses (MOOCs), where it is used as a rough proxy for course quality and learner engagement.

The formula is students who complete / students who enroll × 100, but what counts as "enroll" and "complete" varies by platform, which makes the metric hard to compare across providers: a course requiring only a click to register reports a very different denominator than one requiring payment or an application. This differs from student retention rate, which tracks continued enrollment across terms or years rather than finishing one course.

MOOC completion rates are notoriously low compared to instructor-led or credit-bearing courses, since free, self-paced enrollment attracts many casual browsers with no intention of finishing, and platforms increasingly report engagement segmented by learner intent to avoid this misreading. Practitioners pair completion rate with cohort analysis by enrollment source and with engagement rate metrics like time-on-task to distinguish disengagement from a course that is simply too difficult, and watch module-by-module drop-off for patterns resembling churn rate.
