1. Access to official database or public information: The examination and approval authority will use the database or public information provided by official websites such as education departments, human resources and social security departments to inquire about the qualifications and background information of teachers in training institutions. This information can include teachers' educational background, professional qualifications, teaching experience and so on.
2. Examination and approval of qualification certificates: The examination and approval bureau will require training institutions to provide teachers' relevant qualification certificates, such as teacher qualification certificates and professional qualification certificates, and review these certificates to ensure their authenticity and validity.
3. Verification of personal data: The examination and approval authority will ask the training institution to provide the personal data of the teacher, such as ID card, education certificate, work experience, etc., and conduct verification to ensure the accuracy and authenticity of these data.
4. On-site investigation: The examination and approval bureau will conduct on-site investigation on training institutions, including the evaluation of teachers' on-the-job situation, teaching level and teachers' morality and style. This can be achieved by observing the teaching site and communicating with students and parents.
