Final answer:
Observable behaviours that showcase competency levels within a set are known as indicators, which are distinguishable from criteria, the measurable standards used for comparison.
Step-by-step explanation:
Observable behaviours that indicate the level of competency within each competency set are known as indicators. Competencies are made up of a combination of skills, abilities, and knowledge that can be observed and measured. An indicator provides a specific behaviour that can be observed, which shows how well an individual is meeting a certain criterion or standard within a competency set.
While a criterion is a specific standard or attribute that can be measured, such as weight or size, an indicator is more about the observable action that demonstrates competence. Indicators are often used in various settings, including educational institutions and the workplace, to assess performance. Some other related terms include metrics, which are quantifiable measures, and benchmarks, which are reference points against which other things can be compared.
