According to characteristics of the Skill operation paper, this paper proposes to build constraint mode around the skill point. It achieves the skills item bank automated test paper using the combination of the distribution. It designs skill point matrix constraint model. It discusses three key components: parameter validation optimization, the program generates combinations of skill points and becoming the skills test paper. The example indicates the this method can achieve the skills item bank to satisfy the skills points test paper. The method is simple, highly efficient and of excellent quality. It is very suitable for application of the Skill operation paper.
