AICC vs SCORM: Understanding the key differences

Do you know how eLearning courses interact with their LMSs? Thanks to some established technical standards or guidelines, which have contributed tremendously to the development of the eLearning world.  

AICC, SCORM, and xAPI are some of the most commonly used technical standards in e-learning. They define how e-learning courses interact with LMSs to facilitate course tracking. Let’s understand these standards in detail, see how they facilitate communication between eLearning content and an LMS, and learn some key differences between them. Let's get started. 

What is AICC?

AICC stands for "Aviation Industry Computer-Based Training Committee". It was developed in the early 1990s primarily for the aerospace industry. AICC is an organization that develops guidelines for the development of training programs in the aviation industry. However, its principles and standards have since become fundamental in the broader field of eLearning.

The AICC standard defines how online learning content and Learning Management Systems (LMS) should communicate with each other. 

What are the various components of AICC?

The AICC (Aviation Industry Computer-Based Training Committee) standard consists of several components that govern:

  • The structure of courses and
  • The exchange of data between:
  • eLearning content and
  • Learning Management Systems (LMS)

Let us study its two key components:

Component I: Course Structure

AICC-compliant courses typically have a hierarchical structure, which consists of:

  • Lessons
  • Topics, and Subtopics

This structure organizes the content in a logical sequence and makes it easier for learners to understand the course. Courses include navigation controls such as:

  • Menus
  • Buttons, and
  • Links

These navigation controls help facilitate learner interaction and movement between different sections of the course.


  • AICC specifies how course content should be packaged for delivery. This commonly includes guidelines for organizing:
  • Multimedia elements
  • Assessments, and
  • Other learning resources within the course structure.
  • AICC-compliant courses often include:
  • Assessments
  • Quizzes, or
  • Tests
  • These help in evaluating learner comprehension and progress.
  • AICC standard defines:
  • How these assessment components should be structured? and
  • How can they be integrated into the course?

Component II: Data Exchange

AICC defines a communication protocol, which:

  • Allows eLearning content to communicate with the LMS
  • Guides how data (such as learner progress, assessment results, and completion status) should be transmitted between:
  • The content and
  • The LMS.

AICC also specifies a data model. It defines the structure and format of data exchanged between the content and the LMS. This often includes standardized data elements and fields for 

  • Tracking learner activity
  • Storing assessment results, and
  • Recording other relevant information

Lastly, the standard outlines methods for transferring data between the content and the LMS, such as:

  • HTTP communication or
  • Other network protocols

These methods ensure secure and reliable data exchange between the two systems.

What is the primary feature of AICC?

At its core, AICC serves as an interoperability standard. In the context of eLearning, interoperability means:

  • The ability of educational content (such as online courses, modules, or assessments) to work seamlessly with different Learning Management Systems (LMS)
  • Content developed using the AICC standard can be deployed and managed across various LMS platforms without compatibility issues.

Let’s understand this concept of interoperability better using a hypothetical example:

Say you're an organization that develops eLearning courses for employee training. You've created a series of online courses using a specific authoring tool, which follows the AICC standard for packaging and communication.

Now, your organization wants to deploy these courses across different departments. Each of these departments uses a different Learning Management System (LMS) to manage and deliver training.

  • Department A uses LMS X
  • Department B uses LMS Y, and
  • Department C uses LMS Z

Thanks to the interoperability provided by the AICC standard, you can seamlessly deploy your eLearning courses across all three LMS platforms without encountering compatibility issues. 

Let’s see how it happens:

  • Packaging Content

  • Your eLearning courses are packaged according to the AICC standard.
  • This type of packaging ensures that they are structured and organized in a consistent format.
  • This format can be understood by any AICC-compliant LMS.
  • Communication Protocol
  • The AICC standard defines a communication protocol that allows your courses to interact with the LMS. 
  • This protocol ensures that data can be:
  • Accurately tracked and
  • Recorded by the LMS
  • There are no interruptions caused by any specific kind of platform being used.
  • Deployment Across LMS Platforms
  • You upload your AICC-compliant eLearning courses to each department's respective LMS (X, Y, and Z). 
  • Since all three LMS platforms support the AICC standard, they can recognize and interpret the packaged content correctly.
  • Consistent User Experience

  • Employees across all departments can access the same eLearning courses through their respective LMS platforms
  • They can browse the courses, complete assessments, and track their progress just as they would in any other eLearning environment.
  • Centralized Tracking and Management
  • As learners interact with the courses, their progress and performance data are:
  • Captured by the LMS and
  • Stored centrally
  • This allows administrators to:
  • Monitor learner activity
  • Generate reports, and
  • Assess the effectiveness of the training program across all departments, regardless of the LMS used.

Which eLearning platforms support AICC?

Some examples of eLearning platforms that support AICC include:

  • Docebo
  • This platform supports AICC standards
  • It also offers modern alternatives for online learning experiences
  • Lectora
  • Lectora is compliant with both SCORM and AICC.
  • It allows users to create graded eLearning content
  • isEazy
  • This authoring tool enables the creation of dynamic and accessible eLearning courses
  • All its courses are compatible with AICC standards.

What is SCORM?

AICC was initially developed for the aerospace industry. However, it found broader application in eLearning due to its

  • Security
  • Flexibility, and
  • Robust communication protocols

But, as technology has advanced, newer standards like SCORM (Sharable Content Object Reference Model) have emerged. They offer additional features and improvements over AICC. Let’s understand what SCORM is.

SCORM is a comprehensive set of technical standards. These are designed specifically for eLearning products. Their primary purpose is to perform seamless communication and interaction between:

Let’s understand some key components and functions of SCORM

Component I: Packaging Content

SCORM dictates how eLearning content should be structured and packaged for delivery. This includes:

  • Specifying the format and
  • Organization of files containing the learning materials

Essentially, SCORM ensures that eLearning content is properly packaged. This kind of proper packaging ensures that an LMS can:

  • Easily launch the content
  • Interpret it, and
  • Track it

Component II: Run-Time Communication

SCORM defines the communication protocol between the learning content and the LMS during runtime. It guides how data is exchanged between the two entities, such as:

  • Tracking learner progress
  • Recording assessment results, and
  • Reporting back to the LMS

This robust communication mechanism leads to a seamless flow of information between the content and the LMS.

Component III: Pedagogical Neutrality

It's important to note that SCORM is agnostic to pedagogical concerns. In other words,

  • SCORM focuses purely on the technical aspects of eLearning interoperability.
  • It does not focus on prescribing:
  • Specific instructional methods or
  • Content design principles

This kind of pedagogical neutrality ensures that SCORM-compliant content can work effectively with any SCORM-compliant LMS.

Component IV: Versioning

SCORM has evolved over time. There have been multiple versions released to address evolving needs and technological advancements. Some popular examples are:

  • SCORM 1.2
  • SCORM 2004

Organizations often choose the SCORM version that:

  • Best aligns with their requirements or
  • Supports the content they need to deliver.

Component V: ADL and Rustici Software

The development and maintenance of SCORM are overseen by the Advanced Distributed Learning (ADL) initiative. This initiative is sponsored by the United States Department of Defense (DoD). 

Additionally, companies like Rustici Software specialize in assisting organizations in achieving SCORM compliance. These companies ensure that the eLearning products adhere to the SCORM standards.

Which eLearning platforms support SCORM?

Many eLearning platforms support SCORM. Some popular names include:

  • Calibr.ai
  • Adobe Learning Manager
  • TalentLMS
  • Docebo
  • Absorb LMS
  • eFront
  • GyrusAim
  • Academy Of Mine
  • 360Learning


Both AICC and SCORM serve similar purposes. They help in standardizing e-learning content interoperability. However, they differ in their:

  • Technical specifications
  • Compatibility
  • Flexibility, and
  • Industry adoption

Let's compare AICC and SCORM across various aspects:

  • xAPI supports distributed learning ecosystems
  • It allows data to be collected from multiple sources, such as:
  • Websites
  • Mobile apps
  • Learning games, and
  • Even physical interactions
  • All this collected data is then stored in a centralized Learning Record Store (LRS).
  • Flexible Data Model
  • xAPI employs a flexible data model based on "statements".
  • These statements describe learning activities in a structured format
  • These statements consist of three main components:
  • Actor
  • Verb, and
  • Object
  • Actors represent the learners or users
  • Verbs denote the actions performed (e.g., completed, watched, answered)
  • Objects specify the targets of the actions (e.g., courses, modules, resources).
  • Real-Time Tracking and Analysis

  • xAPI enables real-time tracking and analysis of learning activities
  • It provides organizations with immediate insights into:
  • Learner behavior
  • Preferences, and
  • Performance
  • This data can be used to personalize learning experiences and measure the effectiveness of training programs

  • xAPI is designed to be highly interoperable and extensible
  • These features allow for integration with a wide range of learning technologies and systems
  • It can complement existing standards like SCORM
  • Also, it can be used independently to track learning experiences

How did xAPI overcome the shortcomings of SCORM?

xAPI, or Experience API, addressed several limitations of SCORM. Let’s understand how:

xAPI Tracks Beyond E-Learning Courses

SCORM was primarily designed to track activities within traditional e-learning courses accessed through Learning Management Systems (LMS). However, xAPI expands tracking capabilities beyond these boundaries. It allows organizations to capture data from a wide range of learning experiences, such as:

  • Simulations
  • Mobile learning
  • Virtual reality
  • Social learning interactions, and
  • Real-world experiences

While SCORM uses a fixed data model based on completion status and scores, xAPI employs a flexible data model based on "statements." This flexibility allows organizations to capture a wide range of learning interactions and events, such as:

  • Watching a video
  • Completing a task, or
  • Attending a workshop

xAPI has Wider Interoperability and Extensibility

SCORM has limited interoperability with non-SCORM-compliant systems. However, xAPI is designed to be highly interoperable and extensible. It can:

  • Complement existing standards like SCORM or
  • Be used independently to track learning experiences


Both AICC (Aviation Industry Computer-Based Training Committee) and SCORM (Sharable Content Object Reference Model) offer standards for e-learning content interoperability. AICC was developed in the 1990s for the aviation industry. Gradually, it became fundamental and was adopted in the broader field of eLearning. However, due to its several shortcomings, a newer and better technology started gaining prominence known as SCORM. 

AICC emphasizes hierarchical course structures and specific data exchange formats. It ensures compatibility and communication between content and Learning Management Systems (LMS). 

SCORM, on the other hand, offers modular packaging, detailed run-time communication protocols, and pedagogical neutrality.

Further technological advancements led to the development of xAPI, or Experience API. It is again a better and improved protocol representing a significant advancement over SCORM. xAPI enables comprehensive tracking of learning experiences beyond traditional courses. It has a flexible data model and wider interoperability. 

In essence, while AICC and SCORM remain relevant in certain contexts, xAPI offers a more modern and inclusive approach to tracking learning experiences.
