CaSS
CaSS is an open-source system for describing and exchanging competencies, evidence of attainment, and related learning resources.
What CaSS is
CaSS is an open-source system for describing and exchanging competencies, evidence of attainment, and related learning resources. It translates competency data between systems that organize it differently, and can help users find courses, assessments, books, and games through competencies and framework alignments. It can hold competency-based profiles, transcripts, badges, and credentials for training, credentialing, and career management. CaSS supports importing and exporting competencies in common formats; its developer tools include a REST JSON-LD API, a JavaScript library for browser and Node.js environments, and adapters such as IMS CASE, Open Badges, xAPI, and JSON-LD. Assessment evidence can include scored xAPI events, self-declarations, activity completion, supervisor observation, and tests. Organizations can configure who views, accesses, or edits competencies. Deployment options include public or private cloud, federated architecture, or a lightweight open configuration or one using strong cryptography. CaSS is available under the Apache 2.0 license for commercial and non-commercial use and modification, with code for hosting an instance. Eduworks also offers a hosted, customizable, supported service. The developer overview describes a no-knowledge security architecture in which the server cannot access unencrypted private data or user credentials.
Good
- Apache 2.0 license permits commercial and non-commercial use
- Supports competency exchange across differently structured systems
- Includes REST JSON-LD API and JavaScript library
- Offers configurable access controls and deployment options
Watch out
- Hosted service is offered separately by Eduworks
- Self-hosting requires hosting an instance
Who it suits
CaSS may suit organizations that need to exchange competency information across systems or manage competency-based profiles and credentials. Its API, adapters, and deployment choices may also fit teams integrating learning or credentialing tools.
Verdict
CaSS combines competency records, evidence, resource discovery, and integration tools in an open-source system. Organizations should weigh its deployment and integration options against their own competency workflows.
