Competences represent the effective application of knowledge and skills in specific contexts. They transcend knowledge and skills to explain how knowledge and skills are applied effectively. Competences involve conscious and intentional decision making that combines knowledge, cognitive skills, and attitudes. Competences have both a mental component involving thought and a behavioral component involving competent performance, with competent behavior always associated with conscious thinking. Competences are difficult to directly assess but are typically described in terms of observable behaviors in defined situations.
