Common Cartridge® (CC®)

Common Cartridge® is a standard developed by 1EdTech. Common Cartridge provides a way to package and exchange learning content and assessments. Provides a way to package and exchange learning content  (documents, images, videos, audio files, etc.) into a zip file for easy transport. CC can contain the actual content, or links to the content via LTI  links, all with metadata.

Thin Common Cartridge is a subset of the full Common Cartridge that contains only links and metadata about the content. Today’s digital content comes from a variety of resources making it difficult to integrate. Common Cartridge solves this problem by providing a standard way to package learning content so that it can be exported from one system and imported into another, providing educators and students with greater choice and flexibility to share and reuse content to personalize learning. For more information, see 1EdTech's Common Cartridge Project Group Activity.

Compatibility Check (CCx)

CCx is the software developed and used by 1EdTech to enable the Characterization of products that have already achieved 1EdTech Certification. Characterization is the process by which the interoperability capabilities of a deployed product can be determined. The CCx software produces the characterization reports and is used for the comparison of such reports. It is this comparison which is used to identify the actual interoperability between the two characterized systems. This is the software that is used as a part of the 1EdTech Standards First Program.

Competencies and Academic Standards Exchange (CASE)

CASE® is the abbreviation for the 1EdTech Competencies and Academic Standards Exchange® standard. CASE is a framework for digitally transmitting learning standards, competencies, rubrics, and the relationships among sets of learning standards.  Learn more about the standard: CASE.  For more information on the CASE Network, visit:

CASE provides a consistent, machine-readable format.  

EdTech suppliers (LMS, SIS, LOR, CMS) use CASE to label and package academic standards. 

  • Label: CASE provides each learning standard its own unique identifier. 
  • Package: States (or Learning Standards Issuers) can format and wrap a complete set of standards for a given subject (like a database) so it can be uploaded into a learning platform or digital library. 

Competency Framework Item (CFitem)

1EdTech's Competencies and Academic Standards Exchange® (CASE®) standard uses the term competency framework to refer to academic standards documents published by organizations such as a state department of education and individual learning standards. 

Competency Framework Rubrics

Instruments used to identify performance expectations around a task, product or performance. 

For example, using Bloom’s Taxonomy to determine the depth of learning expected at a grade level.


In 1EdTech terms, compliant has no official meaning. You should be wary of the use of this in reference to a supplier’s reported implementation of a standard, specifically when there is no certification. Also a product’s claim of conformance, without certification should be discounted.  Only certified products have demonstrated adherence to the 1EdTech open interoperability standards.

Comprehensive Learner Record (CLR)

Comprehensive Learner Record (CLR) - the specification that defines a comprehensive digital learner record applicable to education and workforce learning in a verifiable, portable, and interoperable format. 

A CLR is an official document that seeks to capture, record, and communicate learning when and where it happens in a student’s educational experience. This includes learning outcomes from courses, programs and degrees, as well as experience they have outside the classroom that help develop their career ready skills and abilities.

Example: Educators designed the CLR to record more context about learning achievements and the learning journey than is possible with a digital badge.

Computer Adaptive Testing

Computer Adaptive Testing is a standard for establishing interoperability between adaptive testing engines and assessment delivery platforms to adapt a test to students' understanding of the subject matter. For more information, see 1EdTech's Assessment Project Group Activity and the Computer Adaptive Testing Project Group Activity.


Is simply a claim by a supplier that an application or tool demonstrates that it adheres to an 1EdTech specification e.g. that it has implemented the standard’s requirements. 

Only certified products have demonstrated adherence to the 1EdTech open interoperability standards.

Content Consumer

EdTech’s interoperability design relies on two important roles: consumer and provider. Consumers and Providers can be related to tools, content, or services. A Content Consumer ingests content. A Content Consumer would also typically be a learning management system.
