The new stage of free arrangement begins, apart from Kakei-ho.
Upon completion, application can be made for The Third Certificate (Nikyu).

After completing all the studies of the four curricula, lessons continue for  acquisition of a Teacher's Diploma (to be officially certified as Sogetsu  teacher). At this stage, various subjects learned using the textbooks are  reviewed and applied to gain skills of free expression using plant materials.  At the same time, training is required to gain mental preparedness as a  teacher. At the point of completing the required curriculum of both the  technical and mental aspects, application can be made for Teacher's  Diploma Fourth Grade, a Hand-carved Kanban/Name board, and Hand- carved Sekisatsu/Nameplate.
