Vice-Ministers. The NCA follows direction of the Chief Justice and implements decisions from the Council of Supreme Court Justices. Its main role includes assisting the Chief Justice's power on human resource issues of lower ordinary court Judges, planning fiscal budget and expenditure issues for all ordinary courts, and internal inspection for anti-corruption ethics. Judicial Research and Training Institute The 'Judicial Research and Training Institute' (JRTI, ) is currently an institution for training and reeducating lower ordinary court Judges by article 72 of the Court Organization Act. However, it was originally a kind of nation-wide 2-year law school supported by South Korean government before South Korea adopted American styled 3-year law school system in year 2008. Before South Korea adopted American law school system (), South Korea trained its legal professionals mainly by JRTI. Another route was recruitment by South Korean Armed Forces as 'Judge Advocates' (). The JRTI was basically a South Korean conversion of 'Legal Research and Training Institute' () in Japan, which was an institution for training judges, prosecutors and attorneys-at-laws at the same time. The trainees at JRTI was selected by a nation-wide exam on jurisprudence called 'Judicial exam' (). These trainees were commonly trained and competed against each other in the JRTI for 2 years, as their career option after graduation was restricted according to graduation records of JRTI. Graduated trainee with superior records usually choose to become Judges and Prosecutors, while trainees with lower records had to choose working as lawyers in fields. This partially continued civil law tradition of regarding prosecutors as de facto part of judiciary, like French National School for the Judiciary, is reflected in organization of JRTI, as the deputy director (or vice-president) of the JRTI is appointed among Prosecutors by article 74(1) of the Act. Yet after American styled 3-year law school system was adopted in South Korea, the JRTI lost its status as only professional school for law in South Korea, and turned into internal education institute for newly appointed Judges and Law clerks. Some of senior Judges are also retrained in JRTI for technical matters. Also, currently all of training functions for Prosecutors are transferred to 'Institute of Justice' () at Ministry of Justice. Judicial Policy Research Institute Established by article 76-2 of the Court Organization Act in year 2014, the 'Judicial Policy Research Institute' (JPRI, ) is apparatus of the Supreme Court for research on policy issues
