SCORM is a collection of standards and specifications used for e-learning. It can be thought of as a format for creating and delivering interactive learning courses.
The SCORM format enables e-learning courses to be highly customisable and interactive and is popular due to its compatibility with so many web-based Learning Management Systems, such as Clui, and across various devices.
You can upload SCORM files to Clui using the .zip format. At first, the format may appear to be strict, however, SCORM recognises many popular standards while offering a simplified way for those standards to be used together.
