The Complete CAS ACAS Certification Pathway
A step-by-step guide to earning the Associate of the Casualty Actuarial Society (ACAS) designation.
Overview of the ACAS Credential
The Associate of the Casualty Actuarial Society (ACAS) is the first professional credential on the CAS pathway, focused exclusively on property and casualty insurance. Earning your ACAS demonstrates mastery of the mathematical, statistical, and insurance-specific knowledge required for P&C actuarial practice. The credential qualifies you for roles in pricing, reserving, product development, and risk management within the property and casualty insurance industry.
The CAS pathway is more streamlined than the SOA pathway because there is a single credential track focused entirely on property and casualty insurance. Every CAS candidate follows the same exam sequence, which provides a shared knowledge base across the P&C actuarial profession.
Exam Requirements
The ACAS pathway begins with exams shared with the SOA: Exam 1 (Probability, equivalent to SOA Exam P) and Exam 2 (Financial Mathematics, equivalent to SOA Exam FM). These shared exams establish the mathematical foundation that both organizations consider essential for actuarial practice. Passing these exams early, ideally before or shortly after graduation, gives you a significant advantage in the job market.
CAS-specific exams include MAS-I (Modern Actuarial Statistics I), which covers probability models, estimation, and hypothesis testing with insurance applications. MAS-II (Modern Actuarial Statistics II) covers advanced statistical methods, predictive modeling, and machine learning techniques applied to insurance data. These two exams replaced the former Exams 3F and 4 and reflect the CAS's emphasis on modern data science skills.
Upper-Level ACAS Exams
Exam 5 (Basic Techniques for Ratemaking and Estimating Claim Liabilities) is the first exam focused specifically on P&C actuarial practice. It covers the fundamental methods for setting insurance rates and estimating reserves, including loss development triangles, the chain-ladder method, the Bornhuetter-Ferguson method, and basic ratemaking formulas. This exam bridges the gap between mathematical theory and day-to-day P&C actuarial work.
Exam 6 (Regulation and Financial Reporting) covers insurance regulation, statutory accounting principles, GAAP accounting for insurance, the NAIC Annual Statement, and risk-based capital requirements. This exam requires more reading and memorization than the earlier mathematical exams, and candidates often find its qualitative nature to be a significant shift from the quantitative focus of previous exams. Exam 6 has two variants: 6-United States and 6-Canada, reflecting the different regulatory environments.
Additional Requirements
ACAS candidates must complete VEE requirements in Economics, Accounting and Finance, and Mathematical Statistics. These are the same VEE topics required by the SOA and can be fulfilled through approved college coursework or online courses. Credits earned for VEE are accepted by both organizations, so candidates who switch between the SOA and CAS paths do not need to repeat their VEE coursework.
You also need to complete CAS Online Courses covering insurance operations and professionalism. These courses provide practical context about how insurance companies operate, including underwriting, claims handling, distribution, and reinsurance. They are self-paced and can be completed during breaks between exam study periods.
The Course on Professionalism
The CAS Course on Professionalism is a live seminar similar to the SOA's APC. It covers the CAS Code of Professional Conduct, ethical case studies, regulatory expectations for actuaries, and communication with non-actuarial stakeholders. Attendance is required before you can receive your ACAS designation. The course is offered several times per year at various locations, and you should register for a session as soon as you complete your final exam to avoid delays in receiving your credential.
Recommended Exam Sequence and Timeline
The typical exam sequence is Exam 1, Exam 2, MAS-I, MAS-II, Exam 5, and Exam 6. Some candidates take Exam 5 before MAS-II if they are already working in a pricing or reserving role, as the practical relevance can provide motivation and context. The entire ACAS process typically takes three to five years for candidates studying while working full time.
A sample timeline might be: pass Exams 1 and 2 during college or in the first year of employment, pass MAS-I in year two, pass MAS-II in year two or three, pass Exam 5 in year three, and pass Exam 6 in year four. Complete VEE requirements and online courses during gaps between exam sittings. This timeline assumes passing each exam on the first attempt; plan additional time for any retakes that may be needed.
Tips for the CAS Path
CAS exams above the preliminary level are offered less frequently than SOA exams (typically twice per year in the spring and fall), so missing a sitting means a six-month delay. Plan your study schedule to ensure you are ready for each sitting, and register early since testing centers can fill up. Build relationships with other CAS candidates and credentialed actuaries in your organization, as the CAS community is smaller and more tightly knit than the SOA community, and these connections provide valuable support throughout the credentialing process.
