Today Computer Based Training (CBT) is being written by a diverse number of parties using very diverse tools or authoring systems. Many of the CBT lessons being developed can complement and work well with other lessons developed in different locations with different tools by different people. There is a need to allow these complementary lessons to be brought together and used in a single course. However, this cannot be done without defining a standard set of CMI (Computer Managed Instruction) functions and a matching set of CBT functions.
Additionally, there are reasons for courses to be moved from one environment - one CMI system - to another.
- Need to save money by purchasing a single CMI system instead of one for each course to be administered.
- Low cost of administering a single CMI system instead of many.
Consequently there is a need to standardize the description, listing of contents, and sequencing of the lessons in a course.
And finally, there is a need to analyze student performance data accumulated in a lesson. A standard means of describing a student's performance can enable the analysis of diverse lessons, authored by different persons with different systems.
For the above reasons, the purpose of this standard is to:
- Allow different lessons to work with different CMI systems
- Allow courses to move from one CMI system to another with minimal effort (Course interchange/interoperability)
- Allow modification/expansion of a course by any instructor with his/her preferred CMI tools
- Enable easier analysis of student data from different lessons.

| The IEEE LTSC Standard for Information Technology --Learning Systems-- Computer Managed Instruction is composed of 2 (sub)standards: |
P1484.11.1: Data Model for Content to Learning Management System Communication
This Standard describes a data model to support the interchange of agreed upon data elements and their values between a learning-related content object and a runtime service (RTS) used to support learning management. This Standard does not specify the means of communication between a content object and an RTS nor how any component of a learning environment shall behave in response to receiving data in the form specified. This Standard is based on a related data model defined in the "Computer Managed Instruction (CMI) Guidelines For Interoperability," version 3.4, defined by the Aviation Industry CBT Committee (AICC). To balance the need to support existing implementations with the need to make technical corrections and support emerging practice, this Standard selectively includes those data elements from the CMI specification that are commonly implemented; renames some data elements taken from the CMI specification to clarify their intended meaning; modifies the data types of data elements taken from the CMI specification to reflect ISO standard data types and internationalization requirements; removes some organizational structures used in the CMI specification to group data elements that are specific to the AICC community of practice and not generally applicable; and introduces some data elements not present in the CMI specification to correct known technical defects in data elements taken from that specification. The data model supports learner data and preferences, interactions, objectives, content-object entry, exit, and status information, time parameters, and scores. |
1484.11.2: ECMAScript API for Content to Runtime Services Communication
This Standard describes an ECMAScript application programming interface (API) for content-to-runtime-services communication. This Standard is based on an API defined in the "CMI Guidelines for Interoperability," version 3.4, defined by the Aviation Industry CBT Committee (AICC). It defines common API services in the ECMAScript language that enable the communication of information between learning-related content and a runtime service (RTS) used to support learning management. This Standard does not address the data structures that may be transmitted, data security, or communication between an RTS and a related management system.

The IEEE P1484.11 Computer Managed Instruction Specification is based directly on the works from the Aviation Industry CBT Committee (AICC) and the US DoD Advanced Distributed Learning (ADL) Initiative.
The Computer Managed Instruction (CMI) Guidelines For Interoperability, Version 3.4 document, from the AICC, has been the base document for this specification. |
