SCORM defines how course content is packaged and how it communicates with an LMS — reporting completion, scores, and time spent. Because it is broadly supported, SCORM makes courses portable between systems.
The common versions are SCORM 1.2 (most universally supported) and SCORM 2004 (richer sequencing and status reporting). For more flexible, modern tracking — including offline and non-browser activity — many teams look to xAPI.
In ELIL
ELIL exports any generated course to SCORM 1.2 / 2004 (and xAPI), so you can deploy it in an existing LMS — or deliver and track it natively in ELIL.
