Shin'ō Academy

Shinōreijutsuin (Spiritual Arts Academy): sometimes called the Shinigami Academy. This is the academy founded by Genryūsai Shigekuni Yamamoto some 2,000 years ago. It was once called the Shinigami Academy. It changed to spiritual Arts Academy when it developed into an institute for the next generation of the Kidō Corps and the Onmitsukidō as well as the Shinigami of the Gotei 13. In Rukongai, it is still referred to as Shinigami Academy. The academy, which is located in Seireitei, trains future Shinigami for each of the three military arms of Soul Society. Also, the academy is not under the jurisdiction of the Central 46 Chambers.

Appearance
The Institute is a sprawling, multiple story building with architecture typical of Seireitei. It has an open courtyard, many class rooms, dormitories and practice areas for Zanjutsu, Hakuda, Hohō, and Kidō.

Uniform
The uniform of the Academy is similar to the standard Shinigami Shihakushō uniform, but with a different colour scheme. This consists of a red shitagi (under shirt), a white kosode (shirt) with red stripes, red hakama (trousers), white socks and sandals for women. There is a circular symbol on both breasts of the outer shirt. This appears to be the emblem of the Academy. For the male version of the uniform, the red is replaced with blue.

Admission to the Academy
Applicants to the academy must pass an entrance exam in order to be admitted, and likely must demonstrate that they have some Spiritual Energy. The entrance exam seems to be open to any and all who wish to apply, resulting in a wide range of individuals (of any age) joining, from nobles and residents of the more hospitable districts of Rukongai to its more barbaric outer regions. The results of the entrance exam are used to divide up the successful applicants into different classes, with those who obtain the highest grades being placed in the first class. At the start of the academic year, there is a welcoming ceremony for the new students. If an applicant fails the exam, it may be taken again, though presumably only in the subsequent year. Shūhei Hisagi failed the entrance exam twice, only passing on his third attempt. Despite this, he went on to become a Lieutenant in the Gotei 13.

Academy Curriculum
The Academy's curriculum is taught over six-years, though exceptionally gifted students have been known to graduate from the academy in less time than this, such as Kaien Shiba and Gin Ichimaru. In addition to a more general education, the pupils are taught how to control and make use of their Spiritual Energy, as well as the four major Shinigami combat forms of Hakuda, Hohō, Kidō and Zanjutsu. Students also learn how to perform Soul Burials, learning to communicate with the spirit of their Zanpakutō and are prepared for the general duties of a Shinigami. Upon completing the Academy's curriculum, a student will then apply to join a division of the Gotei 13, Kidō Corps or Onmitsukidō.

On occasion, highly talented Shinigami may be admitted to a squad, or even granted a seated position with a squad before completing the full curriculum, or partake in missions with a squad, as Shūhei Hisagi did. The importance of the Academy is undermined somewhat by the influence of the Great Noble Houses, as seen when Byakuya Kuchiki used his influence to have Rukia Kuchiki graduate immediately upon adopting her into the Kuchiki clan, and organized an unseated position with the 13th Division for her.
