Parents teaching their children?
"Non-formal education became part of the international discourse on education policy in the late 1960s and early 1970s. It can be seen as related to the concepts of recurrent and lifelong learning.

Fordham (1993) suggests that in the 1970s, four characteristics came be associated with non-formal education:"
"Relevance to the needs of disadvantaged groups. Concern with specific categories of person. A focus on clearly defined purposes. Flexibility in organization and methods."
