What does competency mean?
Competency is a noun describing the ability to perform a task or function effectively, combining adequate knowledge, skill, and judgment. While closely related to the more general word competence, competency tends to appear in formal, structured contexts: employers list the competencies a role requires, educators assess student competencies against defined standards, and courts may evaluate a person's legal or mental competency before allowing them to act or sign documents. In modern professional language, a competency is typically treated as something identifiable and measurable — communication, data analysis, clinical procedure — rather than a vague overall capability. The word carries neutral to positive connotations: it implies meeting a required standard without necessarily implying excellence, sitting somewhere between mere adequacy and true mastery. Its prominence has grown with competency-based hiring, training, and accreditation systems, making it a staple vocabulary of workplaces, schools, hospitals, and law alike.
An ability, skill, or area of expertise that a person possesses or is formally assessed on, especially in professional, educational, or legal contexts.
"Effective communication is listed as a core competency for all management positions at the firm."
In HR and education, competencies are usually enumerated and measured; in law and medicine, competency can denote formal fitness to perform a duty or make decisions.
The general state or quality of being adequately qualified, capable, or legally fit to undertake a task.
"The judge determined that the witness lacked the mental competency to provide reliable testimony."
This broader sense overlaps heavily with the noun 'competence,' which many style guides prefer in non-technical writing.
The plural is standard and widely used when referring to multiple distinct skills or assessed areas, particularly in job descriptions, curricula, and performance reviews.
"The new leadership framework outlines twelve core competencies that every manager is expected to develop."
"Core competency" became one of the most quoted business phrases of the 1990s — and it owes its life to this single word.

Etymology of competency
Competency derives from the Latin verb competere, meaning 'to come together, agree, or be fitting,' formed from com- ('together') and petere ('to seek or strive'). English adopted it in the late sixteenth or early seventeenth century, alongside its sibling word competence. Because both descend from the same Latin root, they share a family of cognates including compete, competition, and competitive, all of which preserve the idea of striving toward a goal or standard.
