This study extracts the plan that is suitable to open education through the assessment and analysis of the open education environment. For this, the questionnaire survey of teachers at the elementary school in Kyengsang-bukdo was used. The results of this study can be summarized as follows; 1) In the estimation of satisfaction on the classroom environment for open education, although the score of "Comfortableness" is high, the scores of "Variety", "Convenience", and "Silence" are low in satisfaction. 2) The image on the classroom environment is highly regarded in general in "Stability", "Nobleness" and "Activity". However, it is necessary to devise some methods to improve the image on "Stability", when removing the wall between classrooms and corridors. 3) To improve the satisfaction and image associated with classroom environment, it is important to maintain suitable size of school and density of classroom. 4) The factors of satisfaction and those of image are correlated each other. Thus, to enhance the total image on the open class, it is necessary to improve the whole classroom environment.
