INTENDED AUDIENCE
The SCORM 2004 4th Ed. Documentation Suite contains technical information for a
variety of audiences, but product vendors needs to know which specific information is
critical to making their learning products SCORM 2004 4th Ed. compliant.
The target audiences for this document are LMS vendors, content providers, content
package creators and those building tools to support these activities.
CONFORM, COMPLY, AND CERTIFY
Since SCORM 2004 was published, several specifications in SCORM documentation
have been accepted as IEEE standards. When using standards, the appropriate term is
compliance. You either comply with the standard, or not. The path to certification is
compliance. Conformance is not an option. Accordingly, ADL is amending and
updating publications to reflect SCORM-compliance. The SCORM Test suite has been
renamed the SCORM Test Suite. This change will be reflected in a future reissuance of
DoDI 1322.26. ADL recognizes that there are many documents within our archives that
cite compliance. Most are in .pdf or other file formats that cannot be changed. The
SCORM 2004 4th Ed. Documentation Suite reflects this change in terminology.
A product that is SCORM certified has been independently tested by one of the ADL
Certification Testing Centers and after passing the SCORM Test Suite, becomes “ADL
Certified.” ADL certification assures consumers of distributed learning content and
systems that certified products have successfully implemented SCORM’s requirements.
