Other, more specific shades of meaning are also found in the literature. For example, instead of generic competences, there are references to key competences: Key competences are context-independent, applicable and effective across different institutional settings, occupations and tasks. These typically include basal competences, such as literacy, numeracy, general education; methodological competences, like problem solving, IT skills, communication skills, including writing and presentation skills; and judgement competences, such as critical thinking. (Winterton, Delamare-Le Deist, Stringfellow, 2006, p. 33) A series of other terms used in the literature on competences are defined in the box below.
