A job competency can be defined as the skills, traits, qualities or characteristics that contribute to a person’s ability to perform responsibilities in an organization. It is a cluster of knowledge, skills, and abilities (KSAs) that an individual possesses.
The competencies are generally divided into two categories, threshold competencies that an individual requires to perform the job at the workplace, and differentiating competencies are those that are present in superior performers but are not present in the average performers.
