Globally, there are currently three major competency models for healthcare professions education: CanMEDS 2015 in Canada, Accreditation Council for Graduate Medical Education Six-Competency model in the United States, and Tomorrow's Doctors in the United Kingdom. An investigation by the Revision Committee for the Japanese National Model Core Curriculum revealed that these competency models had been utilized in seven countries. In each country investigated for revision, medical schools were allowed to implement these major competency models flexibly. Although each university has a high degree of freedom in curriculum design and educational delivery, each country is regulated by a quality assurance system that requires accreditation by the World Federation for Medical Education (WFME) and other organizations. The 2022 Revision of the Japanese National Model Core Curriculum has also been translated into English and released to the global audience in the field.

In this revision, we have attempted to align the Model Core Curriculum for Medical Education competency, "problem-solving ability based on specialized knowledge," with the "Standards of National Examination for Medical Practitioners." The major diseases and syndromes in "Essential Fundamentals" correspond to the basic diseases in Table 1 of the Core Curriculum, symptoms, physical and laboratory examinations, and treatment in "General Medicine" correspond to the items in Table 2 of the Core Curriculum, and the diseases in "Medical Theory" correspond to the diseases in PS-02 of the Core Curriculum. The validity of the diseases in the Core Curriculum was verified using the evaluation results of the examination level classification of the "Research for Revision of National Examination Criteria." Approximately 690 diseases were conclusively selected. This revision mentions the number of diseases in the Core Curriculum for the first time. Hopefully, this will lead to a deeper examination of diseases that should be studied in medical schools in the future.
