SCORM 2004 3rd Edition
October 2006 
SCORM 2004 3rd Edition continues to build upon a common Web-based "Content Aggregation Model" and a "Run-Time Environment" for learning content.  SCORM continues to solidify its collection of specifications and standards adapted from multiple sources to provide a comprehensive suite of e-learning capabilities that enable interoperability, accessibility and reusability of Web-based learning content.

SCORM 2004 3rd Edition introduces changes from past SCORM 2004 editions.  These changes fall into several categories: clarification of concepts, clarification of requirements, changes due to standardization/specification efforts, best practices from the ADL Community, enhancements and bug fixes.

With the release of SCORM 2004 1st Edition, ADL decided to change the versioning so that each book can be maintained independently. The number of specifications and the sheer size of the documents have made this change necessary to manage revisions and corrections to the document set.  Note: The ADL Technical Team no longer supports this edition.
