Skills and knowledge are key aspects of education and employment. Skill can be described as an ability to perform a particular activity that may be developed through vocational training or practice. Knowledge is a familiarity, awareness or understanding that has been acquired through experience or education; knowledge supports and informs skills. Skills and knowledge are at the heart of the education and training system; they are intertwined and often considered from many stakeholder perspectives, including students, workers and employers. Research in this area often centres on current and future capabilities that workers must have to fulfil business or industry requirements with a focus on how the education and training systems can help meet these needs. Government and economic perspectives are also central to these considerations.
