In the context of the reform to “delegate power, improve regulation, and update services,” there is a tendency towards centralized approval and separation of approval and management in the administrative authorization reform. The reform of teacher qualification system, a type of administrative authorization for market entry, also manifests the same trend and characteristics. The focus of teacher qualification accreditation is gradually shifted from ex-ante licensing to interim and ex-post regulation. The notification-commitment system, and the system of supplementary or exempt examination are applied in the ex-ante licensing to provide applicants with more efficient and convenient application facilities. Regular registration and revocation of teacher qualification are adopted in the interim and ex-post regulation to strengthen the supervision of teacher qualifications. In the future, teacher qualification accreditation bodies can further improve their pre-licensing examination methods, strengthen the coordination between approval and supervision, focus on the interim and ex-post regulation, improve service awareness and ability, and constantly improve the teacher qualification system.
