Schema

http://schema.cassproject.org/0.3/

Framework

http://schema.cassproject.org/0.3/Framework

Organize and scope competencies and other objects.

A Competency Framework or simply Framework is a collection of competencies and relations between competencies in the framework and potentially between competencies in the framework and competencies in other frameworks. In practice, a Framework represents competencies related to a specific job, task, organization, career, knowledge domain, etc.

Competency

http://schema.cassproject.org/0.3/Competency

Skills, Knowledge, Abilities, etc.

Competencies include skills, knowledge, abilities, traits, and combinations thereof that are needed to perform a task or job. In CASS, competencies are identified and located using a globally unique ID. Competencies can be further described using titles, descriptions, levels, indicators (coming soon), roll-up rules, and relationships to other competencies.

Assertion

http://schema.cassproject.org/0.3/Assertion

Make claims of competence about individuals.

A claim of competence in CASS is called an Assertion. It states with some confidence that an individual has mastered a competency at a given level, provides evidence of such mastery, and records data such as the time of assertion and the party making the assertion.

Relation

http://schema.cassproject.org/0.3/Relation

Structure and relate competencies within a framework.

A relation specifies an relationship between two competencies. With it, one can express super-sub relationships through the 'narrows' relation, pre-requisite relationships through the 'requires' relation, equivalence, and many more.

Level

http://schema.cassproject.org/0.3/Level

Specify the performance levels of a competency.

When an individual's performance in a competency can be measured, a level specifies milestones that an individual can reach, creating fine-grained distinction between the proficient and the adept.

RollupRule

http://schema.cassproject.org/0.3/RollupRule

Encode inferential rules used to determine rollup.

When no direct evidence of an individual's competence is available, CASS uses assertion processing to estimate competence. Rollup Rules provide a means of encoding rules that govern when competence is warranted in the absence of direct evidence.
