In language assessment, the contents and approach of assessment are of critical importance to validity. Taking into account the concept of assessment for learning (AfL) and recent developments in Chinese language curriculum, this article aims to establish a system that better assesses listening, speaking and oral interaction skills of Chinese language. The system consists of a framework of listening, speaking and oral interaction skills, a multiparty (including teachers, parents and students, etc.) assessment process, and diverse assessment approaches. This system of oral assessment will not only help to achieve higher validity, but will also guide students to further improve their listening, speaking and oral interaction skills.
