Three years. The continuing education of consulting engineers is a cycle every three years, from August 1 of the third year to July 3 1. In one cycle, consulting engineers should participate in continuing education for a total of 120 hours, including 72 hours for public courses and 48 hours for professional courses.

The form of continuing education for consulting engineers is mainly based on the network. Consulting engineers log on to the consulting engineers' continuing education network platform and study according to the teaching guidance. During the learning process, the system automatically tracks and checks the online situation of students.

Consulting engineers can freely arrange the time for continuing education according to their own actual conditions, and the hours of continuing education completed each year can be rolled into the next year. Continuing education hours completed in one cycle can only be valid in this cycle.
