The Advanced Distributed Learning (ADL) Initiative was founded by the DoD in 1997 and charged with developing and implementing technologies across the DoD and federal government. Part of the ADL charter is to collaborate with government, industry and academia to promote international specifications and standards for designing and delivering learning content; the shareable content object reference model (SCORM) is one result of those efforts.
SCORM is a design specification in which learning assets are collected into shareable content objects (SCOs) which can then be aggregated in a plethora of combinations in order to suit the purpose of a particular instructional implementation. The aggregations of of SCOs are structured into an organization and then delivered as a single content package. SCORM helps instructional designers to integrate their course content with various learning management systems (LMS) like Blackboard, WebCT, or Moodle, including the use of sequencing, recording assessment scores, and tracking student usage of the SCOs.
