The undergraduate talent training plan is a guiding document for professional construction. It is an educational contract between majors and college students. In addition to regular evaluation of the rationality of training programs， professional certification also puts forward various specific requirements. There are many constraints in the preparation of civil engineering professional training plans， which require meeting various requirements such as national standards， certification standards， professional norms， etc. with students as the center， balancing and handling various issues， and reasonably integrating various educational ideas such as integrated general education and interdisciplinary education. The research， analysis， formulation， management and implementation of the training program are all very important education links. The composition of the preparation team， the training program review process， the modification process， the publicity method and the rationality evaluation should have strict mechanisms to ensure that they meet the requirements of professional certification. The training program is also the carrier of new talent training model. The training program of civil engineering specialty of Chongqing University has experienced the development process from pilot optimization of experimental classes to comprehensive promotion. In the process of the reform of major enrollment， the preparation of major training plans may involve coordination between different majors or even different colleges and face more challenges.
