Registration deferrals to the next available exam are considered on a case-by-case basis for life-threatening or very serious illnesses (candidate or immediate family), natural disasters, and mandatory military service. This does not guarantee a deferral to any candidate for any condition but instead provides CFA Institute with the discretion to determine which deferral requests it approves and denies. Candidates awarded a deferral are responsible for all applicable new curriculum charges. Deferral requests must be received by CFA Institute prior to the scheduled exam or within 10 U.S. business days after the exam date.
