At first, informal learning was only delimited from formal school learning and nonformal learning in courses (Coombs /Achmed 1974). Marsick and Watkins take up this approach and go one step further in their definition. They, too, begin with the organizational form of learning and call those learning processes informal which are non-formal or not formally organized and are not financed by institutions (Watkins /Marsick, p. 12 et sec.).
