Taking the bar exam is stressful enough. But the implementation of facial recognition technology in Michigan's and California's bar exam has added another layer of anxiety as accuracy, fairness and privacy concerns creep into test takers' minds.

The botched launch of Michigan's online bar exam, which used ExamSoft software to collect biometric data to verify identities and monitor potential cheating, included some of the 700 bar examinees being temporarily locked out of the test.

But ExamSoft's system crashing isn't bar takers' only anxiety. Some are also nervous that the potential racial bias of facial recognition technology will unfairly flag them as cheating.
