Moreover, if there is a request from a student, individual guidance is also performed.Experience of attendance without a charge is possible for the student who is having admission inquired.

"SPROUTS": From the small children to college students and the people of around 20 years old who have a handicap in development are supported. A small child is instructed by the method based on application action analysis (ABA). Moreover, support which brings up educational guidance and sociality is performed to the student from a schoolchild. Especially in the direction of more than a junior high school student and a high school student, counseling is taken in, and instruction according to each of the student's purpose is served. Since SPROUTS is making to be allowed to support until the one student can become independent in society into the motto, if allowed to carry out the support which left for the long-term view, I will think that it is happy. In addition, SPROUTS also installs the free school for the student of a handicap in development or the student absent from school for a long time.
