Series 65 vs Series 66: Which License Do You Need for Your RIA Career?

Two NASAA exams lead to the same destination: registration as an investment adviser representative (IAR). But the path you take depends entirely on your existing credentials and career trajectory. The Series 65 and Series 66 are not competing alternatives — they serve different populations. This guide explains the structural differences, who should take each exam, and how to make the decision quickly.

The Core Difference: What Series 7 Changes

The most important structural fact about the Series 65 vs. Series 66 decision is this: the Series 66 requires a FINRA Series 7 as a co-requisite or pre-existing license. You cannot take the Series 66 without a Series 7.

This requirement exists because the Series 66 was designed to add the investment advisory dimension to an existing broker-dealer representative. If you are already licensed to sell securities products through the Series 7, you need only add the advisory layer — and the Series 66 provides that in one exam rather than two (the Series 63 and Series 65 separately).

The Series 65, by contrast, stands alone. No prior license is required. Any individual can register and sit for it. This makes it the go-to exam for:

• Professionals transitioning directly to pure investment advisory roles
• Entrepreneurs launching RIAs without a broker-dealer affiliation
• Fee-only financial planners who do not want or need securities dealing authority

Series 65: Who Should Take It

Take the Series 65 if any of the following apply to you:

You are launching an independent RIA and do not plan to conduct securities transactions as a broker-dealer. Pure advisory models — fee-only financial planning, investment management, hourly planning — require only the Series 65 (plus state registration).

You do not have a Series 7 and do not plan to get one. Obtaining the Series 7 requires employer sponsorship from a FINRA-member broker-dealer. If you are not working for a broker-dealer, you cannot get a Series 7, so the Series 66 path is unavailable to you.

You are joining a state-registered RIA (not a broker-dealer) that does not require its IARs to hold a Series 7.

You are in insurance or financial planning and moving toward fee-based advice without transitioning to a broker-dealer firm.

You are a CFP, CPA, or attorney adding investment advisory services to your existing practice.

Series 66: Who Should Take It

Take the Series 66 if any of the following apply to you:

You already hold a Series 7. The Series 66 replaces both the Series 63 and Series 65, so it is more efficient than taking both exams separately. If you hold a Series 7 and need investment advisory authority, the Series 66 is the correct path.

You are simultaneously obtaining a Series 7. Many candidates take the Series 7 and Series 66 together as part of entering a career at a wirehouse, regional broker-dealer, or dual-registered firm. You can sit for them simultaneously — you just need to pass both before registering as an IAR.

Your employer requires both broker-dealer and advisory capabilities. Wirehouse financial advisers, bank-based investment consultants, and dually registered representatives need both selling and advisory authority. The Series 7 + Series 66 combination provides both.

You work at a firm that is both a broker-dealer and an RIA. Many large firms operate as dual registrants — registered as both a broker-dealer with FINRA and as an investment adviser with the SEC or states. Employees at these firms typically need both the Series 7 and Series 66.

Content Comparison: What Each Exam Tests

The two exams reflect their different target populations in what they test:

Series 65 Content Areas

| Content Area | % of Exam | Questions | |---|---|---| | Economic Factors and Business Information | 15% | 18 | | Investment Vehicle Characteristics | 25% | 30 | | Client Investment Recommendations & Strategies | 30% | 36 | | Laws, Regulations, and Guidelines | 30% | 36 |

The Series 65 devotes substantial weight to investment vehicles and client recommendations because its candidates may not have a prior securities education (unlike Series 7 holders). The laws section covers both federal adviser law and state law comprehensively.

Series 66 Content Areas

| Content Area | % of Exam | Questions | |---|---|---| | Economic Factors and Business Information | 10% | 9 | | Investment Vehicle Characteristics | 19% | 17 | | Client Investment Recommendations & Strategies | 26% | 23 | | Laws, Regulations, and Guidelines | 45% | 41 |

The Series 66 dramatically reduces the investment vehicle and economic content (presuming this is already covered by the Series 7) and dramatically increases the legal and regulatory weight. Nearly half of the Series 66 is laws, regulations, and guidelines — reflecting its function as an "advisory layer" for candidates who already have a securities foundation.

Practical Difference for Studying

If you are considering both exams, the content difference means:

• Series 65 studying: Comprehensive coverage of finance fundamentals, portfolio theory, and securities law
• Series 66 studying: Focused on state securities law, fiduciary duties, and advisory-specific regulations; less review of investment products

Series 7 holders often find the Series 66 shorter to prepare for (50–70 hours) because they already know the investment vehicle content from their Series 7 study. Candidates without a Series 7 must use the Series 65, which requires more foundational study (80–150 hours).

Pass Rate and Difficulty Comparison

NASAA does not publish official pass rates for either exam, but industry estimates from prep providers suggest:

| Exam | Estimated First-Attempt Pass Rate | Typical Study Time | |---|---|---| | Series 65 | 65–72% | 80–150 hours | | Series 66 | 70–78% | 50–80 hours (for Series 7 holders) |

The Series 66's higher estimated pass rate reflects its population — experienced Series 7 holders with a securities background who primarily need to learn the advisory-specific regulatory content. The Series 65's lower pass rate partly reflects its more diverse population of first-time exam takers.

Which is actually harder? For the populations they serve, they are roughly equivalent difficulty. A candidate without a finance background who took the Series 66 without a Series 7 (which is not allowed, but hypothetically) would find it extremely challenging due to the reduced product content coverage.

Cost Comparison

Both exams charge the same NASAA fee of $187. The difference in total investment comes from:

| Cost Component | Series 65 | Series 66 | |---|---|---| | NASAA exam fee | $187 | $187 | | Study materials | $150–$500 | $100–$350 | | Series 7 cost (if applicable) | N/A | $245 exam fee + $300–$600 study materials | | Total (exam only path) | $337–$687 | $632–$1,032 (including Series 7) |

If you are comparing the two paths purely on cost and do not need the Series 7 for other reasons, the Series 65 alone is less expensive than the Series 7 + Series 66 path.

However, if you are going to work at a firm requiring the Series 7 anyway, the Series 66 adds less marginal cost ($187 + $100–$350 in study materials) to a path you were already taking.

Career Path Differences

Series 65 career paths (pure advisory, no securities dealing):

• Independent RIA founder
• IAR at a state-registered RIA
• Fee-only financial planner
• Investment consultant at an institution (bank, family office) without dealing authority

Series 7 + Series 66 career paths (both dealing and advisory):

• Financial adviser at a wirehouse (Merrill Lynch, Morgan Stanley, UBS, Wells Fargo)
• Adviser at a regional broker-dealer that is also an RIA
• Bank-based financial consultant
• Dual-registered representative at an independent BD/RIA

The key difference is whether your employer or business model involves both selling securities products and providing investment advice, or just providing investment advice. Pure RIAs use the Series 65; dually registered firms need both the Series 7 and Series 66 (or the Series 7 and Series 65, though the Series 66 is typically preferred for efficiency).

Broker-Dealer Employees vs. RIA Professionals

This distinction is fundamental to the decision:

Broker-dealers execute securities transactions as agents or principals. Their representatives — agents — need FINRA licensing (Series 7 for general securities; other licenses for specific products). Broker-dealers operate under a suitability standard (Regulation Best Interest as of 2020).

Investment advisers provide advice about securities for compensation. Their representatives — IARs — need NASAA licensing (Series 65 or Series 66). Investment advisers operate under a fiduciary standard.

Some firms are dually registered — operating as both a broker-dealer and an investment adviser. Representatives at these firms need both a FINRA license (Series 7) and a NASAA license (Series 66 or Series 65).

When you consider where you want to work, the licensing path follows naturally:

• Pure RIA → Series 65
• Broker-dealer with advisory services → Series 7 + Series 66
• Insurance company adding advisory services → Series 65 (usually)

What If You Already Have the Series 65 and Get a Series 7 Later

If you currently hold the Series 65 and later obtain the Series 7, you do not automatically "convert" to a Series 66 — nor do you need to. You can continue holding the Series 65 as your investment advisory license while adding the Series 7 for dealing authority.

However, some candidates choose to take the Series 66 after obtaining the Series 7 to consolidate their regulatory footprint. This is optional and typically unnecessary — the licenses serve different regulatory purposes and can coexist.

One consideration: if you hold the Series 65 and the firm where you work later requires the Series 63 (Uniform Agent State Law Exam) for securities dealing at the agent level, you cannot use your Series 65 to satisfy that requirement — the Series 65 is for the advisory side only. The Series 63 or Series 66 is needed for the broker-dealer agent role.

Can You Take Both

Yes, there is nothing preventing you from taking both the Series 65 and Series 66, and some candidates do so — for example, holding a Series 65 as a legacy license while later adding a Series 7 and Series 66. However, most states will recognize only one investment advisory license per IAR registration, so holding both provides limited practical benefit.

From a regulatory compliance perspective, your state registration will reflect either the Series 65 or Series 66 (whichever you used for that registration), but passing both is not prohibited.

State-Specific Considerations

The Series 65 is accepted in 48 states as the qualifying examination for investment adviser representative registration. California, New Hampshire, New York, and Wyoming have their own processes and may not require the Series 65 (or accept it in modified form). Always verify with your specific state securities regulator.

The Series 66 is similarly accepted across most states but is subject to the same state-by-state verification requirement. Some states have specific continuing education or additional examination requirements regardless of which qualifying exam you hold.

The Practical Decision Framework

Answer these three questions in order:

1. Do you currently hold a Series 7?

• Yes → Take the Series 66
• No → Proceed to question 2

2. Are you required to obtain a Series 7 for your current or planned employment?

• Yes → Take the Series 7 and Series 66 together
• No → Proceed to question 3

3. Do you plan to provide investment advice as a fee-only or independent advisory practice?

• Yes → Take the Series 65
• Unsure → Take the Series 65 (it is the more flexible standalone option and does not close any doors)

FAQ

Q: Can I switch from Series 65 to Series 66 if I later get my Series 7? A: You can take the Series 66 after obtaining your Series 7, which would give you both licenses. However, for your IAR registration, you typically only need to reference one — and your Series 65 remains valid. You do not need to "switch"; you simply add credentials.

Q: Does the Series 66 cover everything the Series 65 does? A: No. The Series 66 covers less investment vehicle content and less portfolio theory than the Series 65, on the assumption that Series 7 holders already have that knowledge. If you take the Series 66 without a Series 7, you may have gaps in your investment product knowledge.

Q: Is the Series 66 easier than the Series 65? A: For Series 7 holders, typically yes — mainly because they already know much of the investment vehicle content and can focus their study on the advisory-specific regulatory material. Objectively, the pass threshold is slightly higher (73% vs. 72%) and the regulatory content is more concentrated, so it is not universally easier.

Q: Which exam do I need if I work for a bank? A: Depends on your role. If you are providing investment advice for a fee, you need the Series 65 (or Series 66 if you also have a Series 7). If you are also executing securities transactions, you need a Series 7 and Series 66. Some bank employees are exempt from certain registration requirements if their advisory activities are incidental to their banking activities — check with your compliance department.

Q: My employer is requiring the Series 66. Do I need to take the Series 7 first? A: You must have a Series 7 (or hold it concurrently) to sit for the Series 66. If your employer requires the Series 66, they will need to sponsor your Series 7 enrollment first or simultaneously.

Q: If I want to work at a fee-only planning firm, which do I need? A: Fee-only planning firms that are registered investment advisers (not broker-dealers) require the Series 65 for their IARs. The Series 66 would require a Series 7, which is not needed for a fee-only practice.

Q: What happens to my Series 65 if I become registered with the SEC instead of a state? A: Your Series 65 remains the qualifying examination regardless of whether your firm registers with the SEC or with states. SEC registration vs. state registration is a firm-level decision based on AUM; your individual IAR license is governed by the state where you primarily conduct business.

Q: Are there any jobs that require both the Series 65 and Series 66? A: No legitimate job requires both. They serve the same regulatory purpose (IAR licensing) through different exam paths. Some professionals hold both as a result of career transitions, but it is not a requirement for any specific role.
