Educational methods include storytelling, discussion, teaching, training, and directed research.

Education frequently takes place under the guidance of educators, but learners may also educate themselves.

Education can take place in formal or informal settings and any experience that has a formative effect on the way one thinks, feels, or acts may be considered educational.

The methodology of teaching is called pedagogy.

A nonprofit organization (also known as a non-business entity) is an organization whose purpose is something other than making a profit.

A nonprofit organization is often dedicated to furthering a particular social cause or advocating for a particular point of view.

In economic terms, a nonprofit organization uses its surplus revenues to further achieve its purpose or mission, rather than distributing its surplus income to the organization's shareholders (or equivalents) as profit or dividends.

This is known as the non-distribution constraint.

The decision to adopt a nonprofit legal structure is one that will often have taxation implications, particularly where the nonprofit seeks income tax exemption, charitable status and so on.
