Non-formal learning is a loosely defined term covering various structured learning situations, such as swimming sessions for toddlers, community-based sports programs and conference style seminars, which do not either have the level of curriculum, syllabus, accreditation and certification associated with 'formal learning', but have more structure than that associated with 'informal learning', which typically take place naturally and spontaneously as part of other activities. These form the three styles of learning recognised and supported by the OECD.
