'SCORM' stands for Shareable Content Object Reference Model It is a technical standard for building eLearning materials.
It s a collection of specifications that enable interoperability, accessibility and reusability of web-based learning content. SCORM content can be delivered to students via any SCORM-compliant Learning Management System (LMS) using the same version of SCORM.It means that packages can be created through programmes such as iSpring or they can be bought in. This tool can be used with a variety of SCORM packages but they cannot be created in SOL, only hosted on it.
