Hardest Actuarial Exam: Which One Stumps the Most Candidates
Identifying the most difficult actuarial exams based on pass rates, study requirements, and candidate experiences.
The Toughest Preliminary Exams
Among preliminary exams, Exam LTAM (and its successor ALTAM) consistently earns the reputation as the hardest. Its combination of vast content, written-answer questions, and conceptual complexity produces some of the lowest pass rates. CAS Exam MAS-II is similarly challenging, with its integration of advanced statistics and insurance applications. These exams represent a significant step up from the earlier preliminary exams and serve as gatekeepers to the associate credential.
Fellowship Exams
Fellowship exams are universally considered harder than preliminary exams. CAS Exams 7, 8, and 9 have pass rates that sometimes dip below 30%. SOA fellowship exams vary by track but are similarly demanding. The difficulty of upper-level exams comes from their breadth (covering entire practice areas), depth (requiring nuanced professional judgment), and format (multi-hour written-answer exams with complex scenarios). Many actuaries consider the fellowship exams the most intellectually demanding professional examinations in any field. The journey from first preliminary exam to fellowship typically takes 7 to 10 years of sustained effort.
