One student’s project is always evaluated by many teachers on multi criteria. If the mean score of projects are similar, it will be hard to compare them each other. However, if there has difference between score by different teachers or by different criteria, we can determine the real assessment of projects. In this paper, we apply the hesitant fuzzy set and multi-attribute decision making to evaluate student’s projects. We have high rating on project which has low chaos on score by different teachers or by different criteria. 2021 Ieee.
