From March 29 through April 7, the Department of Testing Services will be upgrading its online systems to provide a better user experience and incorporate enhanced security features. All ADA online systems and functionalities will be unavailable during this period. No new applications or scores will be processed during this time. This systemwide upgrade will not impact test applications that have already been processed and are awaiting candidates to schedule testing appointments.
