The certificate of China Building Association is printed first, and the issuing time is about 15-30 days.

The certificate of China Architectural Education Association belongs to the "employment certificate" to a great extent. The biggest difference between it and the housing construction department is that the eight-member certificate of the housing construction department can be used not only for employment, but also for "company affiliation" for project bidding and company qualification promotion. There is a time limit for obtaining the certificate from the housing construction department. For example, only 2-3 examinations are organized every year, and it takes 2-3 months to get a certificate. Compared with this, the issuing speed of the association is relatively fast. The association may organize training examinations every month, and the issuing time is about 15-30 days.
