What is SCORM?

Definition, development, objective, and purpose

SCORM stands for Sharable Content Object Reference Model and is a widely used standard for eLearning content. SCORM was developed by the US Department of Defense’s Advanced Distributed Learning (ADL) initiative, with the aim of ensuring interoperability, reusability, and compatibility of learning content across different learning management systems (LMSs).

SCORM is a technical standard that defines how eLearning content should be structured and delivered so that it can be used in different LMSs. It describes specific technical requirements and functionalities for learning objects that ensure they can communicate with LMSs and be exchanged smoothly.

The development of SCORM began in the late 1990s when the US Department of Defense recognized the need to create standardized methods for delivering learning content. Before SCORM, there were several proprietary formats that were often incompatible and made it difficult to integrate content. SCORM was designed to solve these challenges by introducing a universal standard.

The first official SCORM standard, SCORM 1.0, was published in 2000. Since then, there have been several further developments, including SCORM 1.1, SCORM 1.2, and SCORM 2004, each of which brought new functions and improvements. SCORM 2004 is the latest version and includes important enhancements such as sequencing and navigation.

The main objective of SCORM is to simplify the creation and use of learning content by providing a standardized framework that ensures interoperability. SCORM enables you to create content once and use it in different LMSs without further adaptation. This leads to cost savings, wider reach for the content, and more efficient use of learning resources.

SCORM also promotes the reusability of learning objects. Content can be made modular and reused in different courses, making it easier to develop and update eLearning courses.

In short, SCORM is an essential building block of our modern eLearning infrastructure. It provides clear guidelines and standards that improve the quality and consistency of learning content and simplify its dissemination and use.


The most important components of SCORM

SCORM consists of several basic components that work together to ensure the interoperability and reusability of eLearning content. These components are the Content Aggregation Model (CAM), the Run-Time Environment (RTE) and Sequencing and Navigation (SN). Each of these components plays a specific role in the SCORM ecosystem and contributes to the efficient management and delivery of learning content.


SCORM Content Aggregation Model (CAM)

The Content Aggregation Model describes how learning content is organized and structured. It comprises three main features:

  1. Content packaging: SCORM uses XML-based IMS content packaging to bundle and describe learning content. A SCORM package contains all the files and metadata an LMS needs to import the content and provide it to learners.
  2. Content structure: Learning content is organized into a hierarchical structure consisting of courses, modules, lessons, and learning objects. This structure enables you to design and reuse content in a modular way.
  3. Metadata: Metadata describes the properties and content of learning objects to improve their findability and reusability. It contains information such as title, description, author, and keywords.

SCORM Run-Time Environment (RTE)

The Run-Time Environment defines the mechanisms by which the learning content and LMS interact during run-time. The most important aspects of the RTE are:

  1. Launch process: Describes how learning content is started by the LMS and what information needs to be transferred in order to display the content correctly.
  2. API: SCORM uses a JavaScript-based API (application programming interface) to facilitate communication between the LMS and the learning content. This API provides functions with which learning content can send data to and receive data from the LMS, such as progress information, test results, and timestamps.
  3. Data model: The SCORM data model defines a set of data elements that the LMS and learning content use to store and exchange learning progress and other relevant information. This includes elements such as CMI (computer managed instruction), which contains data including current status, scores, and interactions.

SCORM Sequencing and Navigation (SN)

The SCORM Sequencing and Navigation model ensures that learning content is presented in a predetermined order, and governs how learners can navigate through this content. The most important functions are:

  1. Sequencing rules: These rules determine the order in which the learning content is presented, based on the learner’s actions and progress. They enable you to create adaptive learning paths that cater to the learners’ individual needs and performance.
  2. Navigation controls: SCORM defines the navigation elements available to learners, such as ‘Next’, ‘Back’, ‘Repeat’ and ‘Cancel’. These controls allow for flexible and user-friendly navigation through the learning content.

Together, these three components form the backbone of SCORM and facilitate standardized, efficient, and flexible eLearning content management. The interaction between CAM, RTE, and SN ensures that learning content can be used and reused regardless of the platform, making SCORM an indispensable standard in the eLearning sector.

How does SCORM work?

SCORM enables eLearning content to communicate with a learning management system (LMS) in a standardized way. This is achieved through clear structuring and defined mechanisms that ensure learning content can be used regardless of the platform. The following explains how SCORM works, including the design and structure of a SCORM course, communication between learning content and the LMS, and the role of the SCORM API.


Design and structure of a SCORM course

A SCORM course comprises several components that are organized into a specific structure. This structure makes the content modular and reusable. The main components of a SCORM course are:

  • Content package: This is a compressed archive (ZIP file) containing all the files and metadata required for the course. The content package typically contains HTML pages, multimedia files, scripts, and other resources.
  • Manifest file (imsmanifest.xml): This XML file is the heart of the SCORM package and describes the content structure and organization. It contains information about the hierarchy of learning objects, metadata, and dependencies.
  • Shareable content objects (SCOs): SCOs are the basic building blocks of a SCORM course. They are standalone learning objects that can be started and tracked independently of one another. A course can consist of one or more SCOs.
  • Assets: These are the supporting files and resources used by the SCOs, such as images, videos, audio files, and documents.

Communication between learning content and the LMS

SCORM defines a standardized method for communication between the learning content (SCOs) and the LMS. This is done via the SCORM API, a JavaScript-based interface that enables content to send data to the LMS and receive data back. The most important aspects of this communication are:

  • API initialization: When a piece of learning content is started, it initializes communication with the LMS. This ensures that a connection is established between the content and the LMS.
  • Data exchange: While the learning content is active, it can send various data to the LMS, such as learning progress, scores, timestamps, and interactions. 
  • Status check: The learning content can retrieve the current status and other information from the LMS. This facilitates learning progress monitoring and adaptation.
  • Termination: When the learning content is completed, it informs the LMS. This ends the session and ensures that all data is saved.

Role of the SCORM API

The SCORM API (application programming interface) plays a central role in the SCORM architecture. It establishes the connection between the learning content and the LMS and facilitates data exchange. The most important functions of the SCORM API are:

  • Initialize(): Initializes communication with the LMS and prepares the data exchange.
  • Terminate(): Ends the communication and ensures that all data is saved.
  • GetValue(element): Retrieves the value of a specific data element from the LMS.
  • SetValue(element, value): Sets the value of a specific data element in the LMS.
  • Commit(): Saves all changes made during the session.

These features enable learning content to track learner progress, store scores, and manage other relevant data.


SCORM and LMSs: How do they fit together?

Integrating SCORM into a learning management system (LMS) is a decisive factor in the success of eLearning programs. SCORM-compatible LMSs facilitate seamless management and delivery of eLearning content, resulting in an improved learning experience and more efficient training processes.
