This article proposes the use of a new technology to assure student anonymity and reduce bias hazards: identifying students by using bar codes. The limited finding suggests that the use of bar codes for assuring student anonymity could potentially cause students to perceive that grades are assigned more fairly and reassure teachers that they are avoiding identity bias to the greatest extent possible. The authors recommend further implementation of bar code usage to investigate whether students and faculty could achieve positive perceptions as well as whether there are any drawbacks to such use.
