Series 63 vs Series 65 vs Series 66 — the three NASAA exams and when you need each one
These three exams are among the most confusing securities licensing exams because they sound similar but serve different purposes. The Series 63, Series 65, and Series 66 are all NASAA-administered state law exams, and all three are commonly paired with FINRA securities exams. However, they qualify professionals for different roles.
The easiest way to understand the difference is this: the Series 63 is primarily for securities agents, the Series 65 is for investment adviser representatives, and the Series 66 combines both paths for professionals who already hold a Series 7 license.
Choosing the wrong exam can add unnecessary time, cost, and licensing delays. The right exam depends on the role you want, the registrations you need, and whether you already have another securities license.

Understanding the three state law paths: Series 63 vs Series 65 vs Series 66
The Series 63, Series 65, and Series 66 exist because securities professionals can operate under different registration models. While the Series 7 focuses on product knowledge and transaction activity, these NASAA exams focus on the state regulatory framework that determines what type of business you can conduct with clients.
The key difference is the role each exam supports. The Series 63 is designed for securities agents representing broker-dealers. The Series 65 is designed for Investment Adviser Representatives (IARs) providing fee-based advice through Registered Investment Advisers. The Series 66 combines both exams into one qualification for Series 7 holders who want both brokerage and advisory capabilities.
Series 63
State Securities Agent RegistrationThe Series 63 is the Uniform Securities Agent State Law Examination. It is a NASAA exam focused on state securities regulations, including agent registration requirements, broker-dealer obligations, fraud prevention, prohibited practices, and the authority of state securities administrators.
The Series 63 does not qualify someone to sell securities by itself. It is typically paired with a FINRA qualification such as the Series 7 or Series 6. Together, these registrations allow a representative to conduct securities business with clients in states that require state registration.
The exam is shorter than the Series 65 or Series 66, but it should not be treated as an easy formality. State law concepts are different from FINRA rules, and candidates must understand the specific regulatory framework tested by NASAA.
- Required for many Series 7 and Series 6 representatives
- Focuses on state securities laws and ethical practices
- No firm sponsorship required
Series 65
Investment Adviser Representative QualificationThe Series 65 is the Uniform Investment Adviser Law Examination. It qualifies candidates as Investment Adviser Representatives (IARs), allowing them to provide investment advice and offer advisory services through a Registered Investment Adviser (RIA).
Unlike the Series 63, the Series 65 focuses on advisory relationships rather than securities sales. The exam covers investment strategies, portfolio management, economics, retirement planning, client recommendations, fiduciary obligations, and professional ethics.
The Series 65 requires no broker-dealer sponsorship, making it one of the most accessible securities licenses. Career changers, financial planners, and professionals building an independent advisory career often choose this path because it supports fee-based wealth management.
- Registers professionals as Investment Adviser Representatives
- Designed for fee-based advisory and wealth management roles
- No prerequisite license or sponsor required
Series 66
Combined Agent + Adviser RegistrationThe Series 66 is the Uniform Combined State Law Examination. It combines the state securities agent content of the Series 63 with the investment adviser representative content of the Series 65 into a single exam.
The Series 66 was created specifically for professionals who already hold or are pursuing the Series 7. Instead of completing the Series 63 and Series 65 separately, a Series 7 holder can use the Series 66 to qualify for both securities agent registration and Investment Adviser Representative registration.
Although it combines two exams, the Series 66 is not simply an easier version. Candidates must master two separate regulatory frameworks: securities agent laws and investment adviser regulations. It is the most efficient option for professionals who want maximum career flexibility.
- Combines Series 63 and Series 65 requirements
- Ideal companion exam for Series 7 holders
- Provides both brokerage and advisory registration paths
"The Series 63, Series 65, and Series 66 all test state securities law — but each one prepares you for a different professional role. The Series 63 focuses on selling securities through a broker-dealer, the Series 65 focuses on providing fiduciary investment advice, and the Series 66 combines both paths for professionals who want maximum flexibility."
Deep dive: core concepts covered on each NASAA exam
Although the Series 63, Series 65, and Series 66 are all NASAA exams, the tested knowledge areas are very different. The Series 63 is focused on the rules governing securities agents and broker-dealer activity at the state level. It emphasizes registration requirements, prohibited practices, and ethical standards.
The Series 65 moves beyond transaction rules and focuses on the advisory relationship. Candidates must understand economics, investment strategies, portfolio management, fiduciary responsibility, and the regulations governing Investment Adviser Representatives.
The Series 66 combines both regulatory frameworks. It requires knowledge of securities agent regulations from the Series 63 and investment adviser regulations from the Series 65, making it the most comprehensive state law exam for Series 7 professionals.

Which state law path is right for you?
If your goal is representing clients through a broker-dealer, selling securities products, or building a traditional registered representative career, the Series 63 is typically the state law requirement paired with your FINRA qualification.
If your goal is becoming an Investment Adviser Representative, joining an RIA, providing financial planning services, or building a fee-based advisory practice, the Series 65 is the direct path.
If you already hold or are pursuing the Series 7 and want the ability to both execute securities transactions and provide advisory services, the Series 66 is usually the most efficient option.
The dual-registration path
Modern financial professionals increasingly operate under a hybrid model: serving brokerage clients while also providing fiduciary investment advice. That path typically includes the SIE, the sponsored Series 7 Top-Off, and the Series 66. The Series 66 combines the state securities agent requirements of the Series 63 with the investment adviser requirements of the Series 65, creating one efficient qualification for professionals who want both capabilities.
