SCORM (Sharable Content Object Reference Model) is a collection of specifications that define communication between learning content and learning management systems. It allows for reusable learning objects that can be delivered across different LMSs. SCORM specifies content packaging, communication between content and LMS via an API, and sequencing and navigation of content. It defines data models, how content is aggregated and packaged, and rules for tracking interactions and assessment results. SCORM aims to facilitate interoperability and accessibility of e-learning content.
