Aviation Industry Computer-Based Training Committee

1988

The original eLearning standard, born from the aviation industry's need to deliver computer-based training for pilots and technicians.

Sharable Content Object Reference Model 1.2

2001

The standard that changed everything. SCORM 1.2 became the de facto eLearning standard, and thousands of courses built to it still run today.

Sharable Content Object Reference Model 2004 (4th Edition)

2004

The ambitious successor to SCORM 1.2, adding powerful sequencing and navigation but at the cost of complexity.

Learning Tools Interoperability

2010

The standard that lets external tools plug directly into an LMS. LTI solves a different problem than SCORM or xAPI — instead of packaging content or tracking data, it standardizes how a platform launches and communicates with third-party learning tools.

Experience API (Tin Can API)

2013

A radical departure from SCORM's browser-based model. xAPI tracks any learning experience, anywhere, in a simple Actor-Verb-Object statement format.

cmi5: xAPI Profile for LMS

2016

The best of both worlds — cmi5 combines xAPI's flexibility with SCORM's LMS integration, adding back the launch and packaging that xAPI deliberately omitted.
