National qualification accreditation assessors are trained and assessed by training institutions entrusted by CNCA, such as CNCA Institute of Certification and Accreditation Technology, and Provincial Quality Supervision Bureau entrusts Certification and Accreditation Association for training and assessment. Training is irregular, depending on the assessor's situation. Registration is accepted after the training examination notice, and there are quota restrictions. Only after the examination screening meets the requirements, such as major and professional title, can you take the examination, and the examination score requires more than 70 points. CNAS assessors are trained and tested by qualified training institutions, and they can only enter the next round if they score more than 70 points in the first round. They enroll students all the year round, as if there were no places. After passing the qualification examination, the internship evaluation can be arranged directly. After three internships, the team leader will praise and issue a formal evaluator certificate; However, CNAS assessors must be registered and approved by CNAS before they can arrange internship assessment.
