For the purposes of this site, when we refer to course, we typically mean one of the following:

A SCORM Cloud course corresponds to a SCORM, xAPI, or cmi5 package that has been loaded into a SCORM Cloud realm that is connected to a Bright-enabled website.

If you are using LearnDash, a course is an entity configured in the LearnDash configuration screens. Note that a SCORM Cloud course can appear as the content for a lesson or topic within a LearnDash course.

For the most part, if this site doesn't explicitly say "LearnDash course", we are using the term in the canonical context of SCORM Cloud.
