Easy installation, amazing support, and great feature updates that happen on a regular base. LearnDash isn't only in the plugin business, but as an organization, they care about online learning, and that shows in their product roadmap, which is an amalgamation of user input and industry trends.

Very simple structure and straightforward to use. Their support is excellent and they offer video tutorials which I would say are a MUST if you are new to LearnDash. They respect your time and get you on your way knowing what you are doing.

Out-of-the box this ships with more features than any other similar system, specifically advanced quiz types with question types for most situations; certificates, automatic grading. Reporting can be enhanced via their compatible ProPanel plug-in. Support response within 24 hours and then happy to respond when requesting status updates for bug fixes; friendly support team.
