The specialist qualification system of the Japanese Society for Neuroendovascular Therapy was initiated in 2000. The qualified title is ranked as the technical specialist based on the fundamental clinical societies. After completing the training curriculum mainly programmed in the authorized institutes, the examinees are inspected with a triple-tiered comprehensive style using written, oral, and practical tests. Although the overall passing rate is not very high(50-60%), we are holding more than 1,700 specialists and 400 upper-level specialists designated as trainers and consultants in 2022. According to the definition of the organization of specialist authorization, enough knowledge and experience are required for the specialist to practice the standard treatments and offer adequate patient information. The education and training of the specialists are important duties for upper-level supervisors. In our qualification system, upper-level supervisors are strictly inspected and are requested to have a bigger potential to contribute to the development of the society and to take the lead on academic activity as well as clinical work. All qualified specialists should master "neuroendovascular therapeutics" and always brush up on themselves. In the recent rapid progress of our field, the effort to get the newest information about trends and consensus is essential to achieve the most effective and safest treatments.
