Series 65 vs Series 66: Which Should I Take?

The honest breakdown of prerequisites, career paths, and why you only need ONE of these exams (not both).

Last updated February 2, 2026 by Mike Thompson

🎯

They're Mutually Exclusive

You only need ONE. Series 66 supersedes 65 + 63 IF you have Series 7 first.

Series 65 = Standalone

No prerequisites. Take it WITHOUT Series 7. Perfect for independent RIAs and career changers.

🔐

Series 66 = Requires Series 7

Zero independent utility without Series 7. ONLY for dual-role professionals at hybrid firms.

💼

Your Career Path Decides

RIA-only? Series 65. Hybrid firm? Series 66. It's that simple.

The honest truth: If you don't have Series 7 and aren't getting it, you need Series 65. If you already have Series 7 and work at a hybrid firm, you need Series 66. It's that simple. This guide helps you figure out which situation you're in.

Why This Choice is Confusing

What Makes This Confusing

  • Marketing materials are vague about prerequisites
  • The naming is misleading (66 isn't the next step after 65)
  • Prerequisites aren't obvious upfront
  • Everyone has conflicting opinions

The Simple Truth

  • Series 65: Standalone exam for IARs at RIA firms
  • Series 66: Combined exam (63+65) ONLY for people with Series 7
  • They're mutually exclusive: you only need ONE
  • You cannot take Series 66 without Series 7

Decision Tree: Do You Have Series 7?

Do you have Series 7?
├─ NO → Take Series 65
└─ YES
├─ Work at hybrid BD + RIA firm? → Take Series 66
└─ RIA-only firm? → Either works, Series 65 simpler

Side-by-Side Exam Comparison

Aspect Series 65 Series 66
Questions 130 100
Duration 180 minutes 150 minutes
Passing Score 72% 73%
Prerequisites NONE REQUIRES Series 7
Exam Fee $175 $175
Pass Rate 70-75% 65-70%
Independent Utility YES (Full) ZERO without Series 7

⚠️ CRITICAL: Series 66 has zero independent utility without Series 7. If you don't have Series 7 and aren't getting it, Series 66 is completely useless to you. You would be paying $175 (exam fee) plus hundreds for prep materials for a license you can never use.

What Content is the Same vs Different?

Content Overlap

  • Investment products (stocks, bonds, mutual funds, ETFs)
  • Portfolio management strategies and asset allocation
  • Risk assessment and investor profiling
  • Fiduciary duty and ethical obligations
  • Economic indicators and market analysis basics
  • Retirement planning and tax efficiency

Series 65 Unique

  • Comprehensive Uniform Securities Act coverage
  • Deep state registration and compliance requirements
  • Advanced economic analysis and forecasting
  • In-depth financial statement analysis
  • Quantitative analysis methods

Series 66 Unique

  • Securities industry regulations (FINRA focus)
  • Broker-dealer business practices
  • Federal securities laws (builds on Series 7 knowledge)
  • Streamlined state law (assumes Series 7 foundation)
  • Compliance and supervisory procedures

Which is harder? Series 66 has a slightly lower pass rate (65-70% vs 70-75%), suggesting it's marginally harder. However, the difference is small. Don't choose based on difficulty. Choose based on what your job requires.

6 Common Mistakes to Avoid

Taking Series 66 without understanding you need Series 7 first

Why this happens

FINRA will not let you schedule Series 66 without Series 7. Wasted study time.

Better approach

Verify with your firm or FINRA that you meet prerequisites before studying

Thinking Series 66 must be better because the number is higher

Why this happens

They're not sequential steps. 66 isn't an upgrade from 65.

Better approach

Understand they're alternative paths for different career situations

Taking both Series 65 AND Series 66

Why this happens

Series 66 supersedes both Series 63 and 65. Completely redundant.

Better approach

If you have Series 66, you don't need Series 65 or Series 63

Choosing which exam based on which one is easier

Why this happens

Pass rates are similar (70-75% vs 65-70%). Difficulty shouldn't drive decision.

Better approach

Choose based on your job requirements, not perceived difficulty

Not checking with your firm first about requirements

Why this happens

Firm may have specific licensing requirements or may pay for exam prep.

Better approach

Ask your compliance or HR department: Which licenses do I actually need?

Thinking Series 66 skips the need for Series 7

Why this happens

Series 66 REQUIRES Series 7 as co-requisite. It doesn't replace it.

Better approach

If your job requires Series 7, you must take it before or with Series 66

Frequently Asked Questions

Can I take Series 66 without Series 7?

No. FINRA requires Series 7 as a mandatory co-requisite. You must pass Series 7 first (or take it concurrently with Series 66, but that's complex). If you don't have Series 7 and don't plan to get it, Series 66 is completely useless to you. You need Series 65 instead.

Do I need both Series 65 AND Series 66?

No, absolutely not. They are mutually exclusive licenses. If you have Series 66, you don't need Series 65 or Series 63. You only need ONE. Series 66 is designed to replace both Series 63 and Series 65 combined, but only if you have Series 7 first.

I have Series 7 and Series 63. Should I take Series 65 or Series 66?

Take Series 65 only. You already have Series 63. Since Series 66 combines Series 63 + Series 65, taking Series 66 would be completely redundant (and a waste of $175). Just take Series 65 to complete your licensing.

Which exam is harder?

Series 66 has a slightly lower pass rate (65-70% vs 70-75%), suggesting it's marginally harder. However, the difference is small. Don't choose based on difficulty. Choose based on what your job requires. Series 66 assumes you already know Series 7 material, so the comparison isn't apples-to-apples anyway.

Can I work as an investment advisor with JUST Series 65?

Yes, absolutely. Series 65 qualifies you as an Investment Adviser Representative (IAR) at RIA firms. You can provide comprehensive investment advice and charge fees. You cannot sell securities (that requires Series 6 or 7), but advisory-only is a legitimate and popular career path.

What if I want maximum flexibility to work at different types of firms?

You need Series 7 + Series 66 (or Series 7 + Series 63 + Series 65). This dual-licensed path allows you to work at hybrid firms or switch between broker-dealers and RIAs. However, this requires firm sponsorship for Series 7, which is harder to get without existing broker-dealer experience.

I'm a career changer. Which exam should I take?

Almost certainly Series 65. Career changers typically transition directly into RIA firms, which only require Series 65. Series 7 requires broker-dealer sponsorship, which is harder to get without previous securities experience. Series 65 is standalone and can be taken independently.

Does Series 66 completely replace Series 65?

Sort of, but only if you have Series 7 first. If you already have Series 7, then yes, Series 66 gives you all the capabilities of Series 63 + Series 65 combined. But if you don't have Series 7, Series 66 is worthless without it.

Which exam should I take if I'm launching my own RIA?

Series 65. Independent RIA firms typically don't need broker-dealer registration, so Series 7 isn't required. Series 65 alone is sufficient for pure advisory work. Bonus: You can take Series 65 without firm sponsorship, which is helpful when launching independently.

Can I take Series 66 first and then Series 7?

No. FINRA requires Series 7 to be passed BEFORE Series 66. The order is fixed: Series 7 → Series 66. You cannot reverse this. If you need both, start with Series 7.

Know Which Exam You Need?

Compare all Series 65 prep courses side by side, read detailed provider reviews, and find the best course for your study style and budget.
