Through fostering flexibility, promoting cross-domain functionality, and paving the way for interoperable course structure, AICC made seminal contributions that continue to influence contemporary eLearning standards and practices.

SCORM: The Evolution of Digital Learning Standards


SCORM, which stands for Sharable Content Object Reference Model, is a collection of standards and specifications for eLearning. It provides a framework that ensures the interoperability, accessibility, and reusability of eLearning content across various Learning Management Systems (LMSs). SCORM enables the packaging of eLearning content in a standardized format, facilitating the seamless transfer and tracking of learning materials and learner progress across different SCORM-compliant platforms.


The origins of SCORM trace back to the late 1990s when the United States Department of Defense (DoD), through its Advanced Distributed Learning (ADL) initiative, identified the need for a standardized approach to eLearning. The primary motivation was to reduce the cost and improve the efficiency of individualized training and education.

The development of SCORM was a collaborative effort that brought together the insights and guidelines from existing standards of the time, including AICC (Aviation Industry Computer-Based Training Committee), IMS Global, and the Institute of Electrical and Electronics Engineers (IEEE). The goal was to amalgamate the best features of these standards into a new comprehensive standard that would address the challenges faced by the eLearning community.

The first edition of SCORM was released in 2000, with subsequent versions released over the following years, each building upon the previous to enhance and refine the standard. The most widely adopted version is SCORM 1.2, which was released in 2001, followed by SCORM 2004 which introduced sequencing and navigation capabilities among other improvements.

The inception of SCORM marked a significant milestone in the eLearning industry, setting forth a path towards more standardized, interoperable, and efficient eLearning solutions.
