Sharable Content Object Reference Model (SCORM) is a collection of standards and specifications for web-based e-learning. It defines communications between client side content and a host system called the run-time environment (commonly a function of a learning management system). SCORM also defines how content may be packaged into a transferable ZIP file.

SCORM is a specification of the Advanced Distributed Learning (ADL) Initiative, which comes out of the Office of the United States Secretary of Defence.

SCORM 2004 introduces a complex idea called sequencing, which is a set of rules that specify the order in which a learner may experience content objects. The standard uses XML, and it is based on the results of work done by AICC (CBT), IMS Global Learning Consortium, IEEE, and Ariadne
