Alternative education movement in Korea has been mainly expanded by alternative school. Early alternative school was given positive evaluation that it can complement problem in public education system. After that, many alternative schools have been established, and part of those were institutionalized by government approval. However, unauthorized alternative school, especially full-time alternative school mainly bear alternative education movement. Unauthorized alternative schools have common character, disappointment and criticism for public education, and pursuit of alternative education practice. However, it can be said that such common character of alternative schools was changed. Of course, change of educational practice exists because of change of Korean society and educational environment. I discuss whether the change of character actually exists by case study in Gandhi school community.
