Aaron Rasmussen, co-founder of MasterClass, this week announced the launch of Outlier, an online provider of university-level courses. Although the Outlier topics are decidedly more staid, they may serve a higher purpose. That’s because Rasmussen thinks he can help students reduce the cost of earning degrees. Outlier joins the ranks of several other online course providers that market their a-la-carte classes (rather than complete degree programs) as more affordable options for earning college credit despite having no accreditation of their own. It’s largely left up to students to check and verify which institutions will accept which online classes for which degree requirements.
