Choosing Your Third Exam: A Tactical Guide to SOA vs CAS Certification Decisions for Early Actuarial Candidates

You’ve made it through the first two actuarial exams—no small feat—and now you’re staring down a fork in the road: SOA or CAS for your third exam? This isn’t just about picking a test; it’s about setting the course for your career. I’ve seen plenty of candidates agonize over this decision, and while there’s no universal “right” answer, there are smart ways to approach it. Let’s walk through what you need to know, peppered with real-life examples, practical tips, and a dose of honesty about what this choice really means for your future.

Understanding the Basics: SOA and CAS Explained #

First, let’s clarify what SOA and CAS actually are. The Society of Actuaries (SOA) and the Casualty Actuarial Society (CAS) are the two main professional bodies for actuaries in the United States. Both offer rigorous exam pathways to earn your credentials, but they serve different industries. The SOA is your go-to if you’re interested in life insurance, health insurance, retirement, or investments. The CAS, on the other hand, is all about property and casualty (P&C) insurance—think car, home, and business insurance[1][2].

Up until your third exam, the path is pretty much the same for both societies. You’ll take Exam P (Probability) and Exam FM (Financial Mathematics), and you’ll meet some basic educational requirements. But here’s where things start to diverge. Your third exam is where you begin to specialize, and that’s a big deal—because once you’re a few exams deep into one society, switching tracks gets tougher[3].

Why Your Third Exam Matters More Than You Think #

It’s tempting to think of exams as just hoops to jump through, but your third exam is where you start to build momentum in a specific direction. The content becomes more specialized, and the material you study will shape the kind of work you do later. For example, if you take Exam IFM (Investment and Financial Markets) through the SOA, you’re signaling an interest in financial risk and investment products. If you go with CAS Exam 3F (Modeling), you’re diving into the statistical models that power P&C insurance pricing.

This isn’t just academic—it’s practical. Employers pay attention to which exams you’ve passed, and they often use this to gauge your fit for certain roles. Passing a CAS exam can make you a stronger candidate for P&C internships and jobs, while SOA exams open doors in life, health, and retirement.

The Big Question: How Do You Choose? #

So, how do you decide? The most common advice is to follow your first job. If you land an internship or entry-level role in P&C, the CAS route is usually the way to go. If you’re in life, health, or pensions, SOA makes more sense[2]. But what if you’re still in school or haven’t secured that first gig? That’s where things get interesting.

Here’s a practical approach: start by exploring both industries. Talk to actuaries in both fields, attend campus events, and maybe even try an internship in each area. You’d be surprised how many students think they want one path, only to discover a passion for the other after some hands-on experience.

The Flexibility Myth: Can You Switch Later? #

You might hear that you can always switch from SOA to CAS (or vice versa) later. Technically, that’s true—but it’s not as simple as it sounds. The exam syllabi overlap early on, but the further you go, the more they diverge. If you switch after a few exams, you’ll likely have to retake some material, which means more time and money spent studying[1]. That’s why your third exam is such a pivotal moment—it’s your first real step toward specialization.

Salary and Career Prospects: What’s the Difference? #

Let’s talk money. Both SOA and CAS actuaries are well-compensated, but there are differences. P&C actuaries (CAS) often work in a more volatile, data-driven environment, which can lead to higher bonuses in good years. Life and health actuaries (SOA) tend to have more stable career paths, with strong demand in consulting and corporate roles. According to recent surveys, entry-level salaries are comparable, but as you gain experience, your specialization can influence your earning potential. That said, the difference isn’t huge—passion and aptitude for your chosen field matter more in the long run.

Real-Life Examples: Stories from the Field #

Let me share a couple of stories from people I’ve mentored. Sarah started out convinced she wanted to work in life insurance. She passed her first two SOA exams, then took an internship in P&C on a whim. She loved the fast pace and the analytical challenges, so she switched to CAS for her third exam. It wasn’t easy—she had to learn new material—but she’s now a rising star at a major P&C firm.

Then there’s James, who was certain he wanted to work in pensions. He stuck with SOA, but after a few years, he realized he missed the variety of P&C work. He made the switch, but it took him an extra year of studying to catch up. Both paths worked out, but Sarah’s story shows the value of staying open-minded, while James’s reminds us that switching isn’t impossible—just harder.

Actionable Advice: Steps to Take Right Now #

Here’s what you can do today to make a smart decision:

  • Explore Both Fields: Attend information sessions, reach out to professionals on LinkedIn, and consider internships in both life/health and P&C.
  • Assess Your Interests: Are you drawn to the stability and long-term focus of life insurance, or do you thrive in the dynamic, data-heavy world of P&C?
  • Talk to Your Network: Ask mentors, professors, and recent grads about their experiences. Most people are happy to share their stories.
  • Consider Your Location: Some regions have more opportunities in one field than the other. For example, the Midwest has a strong life insurance presence, while the Northeast is a hub for P&C.
  • Don’t Panic: It’s okay if you’re not sure yet. Many actuaries change paths early in their careers, and that’s normal.

The Exam Logistics: What to Expect #

Both SOA and CAS have updated their exam structures in recent years, so it’s important to check their websites for the latest info. Generally, after Exams P and FM, the SOA offers Exam IFM, then a choice between LTAM (Long-Term Actuarial Mathematics) and STAM (Short-Term Actuarial Mathematics). The CAS path includes Exam MAS-I and MAS-II, which focus on statistical modeling and advanced topics in P&C.

The key takeaway? The material gets more specialized, so your study habits need to level up, too. This is a good time to join a study group, find a mentor, or invest in a prep course.

The Personal Angle: What Worked for Me #

When I was in your shoes, I agonized over this decision. I had a summer internship in life insurance, but I was curious about P&C. I decided to take the CAS third exam, just to see how it felt. It was challenging, but I loved the applied statistics and real-world problem solving. That experience shaped my career, and I’ve never looked back.

The point is, you don’t have to have everything figured out right now. What matters is that you’re intentional about exploring your options and making an informed choice.

The Bottom Line #

Your third actuarial exam is more than just another test—it’s your first real step toward a specialized career. Whether you choose SOA or CAS, the most important thing is to pick the path that excites you. Talk to people, try out different roles, and don’t be afraid to change direction if your interests evolve. The actuarial profession is full of smart, curious people who’ve taken winding paths to get where they are. You’re in good company.

So take a deep breath, do your homework, and trust that whichever path you choose, you’re building a foundation for a rewarding career. And remember: the best actuaries aren’t just good at math—they’re passionate about solving real-world problems, wherever that takes them.
