The validity period of the project manager's certificate is 4 years, that is to say, continuing education should be done within 4 years, and then the project manager's certificate should be renewed with the certificate of continuing education; If it has passed 4 years but not more than 5 years carelessly, it can still be done (this is the case of a friend of mine, and later the replacement was successfully guided by the staff of IT Construction Talent Network, and now it is hanging there); If you haven't renewed your license after five years, you may have to go to Beijing to attend face-to-face training and then renew your license with a certificate. Continuing education requires you to study every year in principle, but it may be more troublesome. It is suggested that you can study in the third year of renewal, and then take the exam and get a new card. This is the fourth year, just right.
