Methodology

The methodology we used for this ranking is simple. Using thousands of reviews written by our learners, Class Central was able to sort courses by the Bayesian average of their ratings. Then we removed all the courses with fewer than 20 reviews (the low threshold helps smaller providers to compete on quality) and courses that are unlikely to be offered again. If a course has multiple parts, we only included the first part.
