Education is an important part of the development of human society. With the continuous progress of society, the form of education is also evolving. This paper will introduce three forms of education: pre-institutionalized education, institutionalized education and non-institutionalized education.

Pre-institutionalized education

Pre-institutionalized education started from primitive education synchronized with society and gradually evolved into formal entity education. It marks the emergence of educational subjects, educational objects, cultural communication, educational places and other factors, and jointly constructs an independent form of social activities-educational entities.

Institutionalized education

Institutionalized education refers to a formal and unique education system extending from primary schools to universities. Including traditional academic courses and professional courses and educational institutions suitable for full-time vocational and technical training. Institutionalized education is committed to establishing a sound school system at all levels.

Non-institutionalized education

Non-institutionalized education is an educational form that has not yet formed an independent educational form, but exists objectively. It is closely related to daily life and production, highly integrated, and has not become an independent social institution without being separated from daily activities. Non-institutionalized education embodies the close combination with production and life, such as Coombs' concept of informal education and ilych's concept of "non-school society".
