A national software testing organization has identified several potential technical problems with the online bar exams that many states are planning to administer in October—echoing concerns raised by many who are slated to take the exam remotely next month.

Giving the test online almost certainly means that some percentage of examinees will face internet connectivity issues that could derail their exams, according to a statement released this week by the Association for Software Testing, which is a nonprofit group dedicated to the science of software testing. And plans to have thousands of exam takers log into the exam simultaneously could overwhelm the testing system and lead to examinees getting locked out, it said.
