We have become aware of an intermittent problem with the online test taker registration system. In rare instances, the calendar of available seat time fails to appear for testers during registration. The full test schedule is available in Registration Manager, and testers are encouraged to contact the call center to complete the scheduling process. This issue is a top priority to resolve, and the engineering team is working on a fix. In the meantime, please encourage testers to reach out to the call center.
