More and more researchers are becoming involved through a variety of actions and programs, which divides assess-ment into different branches (such as formative, summative, normative assessment, etc). In the present paper, I will try to empha-sis that collaborative assessment is positive to high school studentsleing outcome, and cooperative and competitive assess-ment should be mixture implemented in Chinese education process rather than only using competitive assessment to evaluate stu-dentsachievement. I hope that Chinese students and teachers could teach or test in the less pressure by reforming the education-al evaluation system.
