Upcoming EFDA Examination Dates

IMPORTANT: Due to Coronavirus (COVID-19), many exams are now "closed" (open only to graduates of an institution) and it is possible exam dates will be rescheduled. If an exam date is pending below, it will have a "pending" icon next to it. It is still recommended to sign up for pending exams to reserve your seat. In the event an exam date is rescheduled to a later date, payment plan due dates will be extended and you will be notified as soon as possible of the change of date.
