Abstract This study put forward 14 hypothetical influence factors of difficulty of exercises in chemistry textbook for senior high school base on literatures, eliminated the inefficient factors after testing and analyzing, and determined the significant influence factors such as calculation requirements, knowledge quantity, question types and behavior target level. Based on the measured difficulty and assignment criteria of the 14 hypothetical influence factors, this paper established difficulty prediction equation, tested the accuracy of the prediction equation and provided the basis for the prediction of difficulty of chemistry test in the future.
