The Series 65 and Series 66 both qualify you to register as an investment adviser representative. Choosing between them is not about difficulty or preference — it comes down to a single factual question about your employment.
Quick answer: If you hold or will hold the Series 7, take the Series 66 — it covers both IAR qualification and state agent registration in one shorter exam. If you will not hold the Series 7, take the Series 65.
Confirm current specifications with NASAA before planning around them.
That is genuinely the whole decision. Everything else follows from it.
Why the Series 65 Is Longer
The Series 65 is a standalone exam. It cannot assume you have passed the Series 7, so it must cover investment vehicle characteristics, economic factors, and analytical methods in more depth on its own.
The Series 66 assumes Series 7 knowledge and therefore spends less time on products and more on law, ethics, and fiduciary duty.
That is why the Series 66 is shorter but not proportionally easier: the material it retains is the material most candidates find hardest.
Both exams cover four broad areas, with different weighting:
For both, the regulatory and ethics content is the highest-yield study area. Fiduciary duty, disclosure of conflicts, custody, advertising, and prohibited practices are where the exams concentrate.
Our fiduciary training resources cover the underlying principles, and the securities licensing exam glossary covers the vocabulary both exams assume.
Fee-only financial planners and RIAs. The classic Series 65 candidate. No broker-dealer, no commissions, no Series 7 — advisory fees only.
Accountants and attorneys adding advisory services. Professionals who want to provide investment advice for a fee without joining a broker-dealer.
Career changers entering the RIA space. The Series 65 has no sponsorship requirement in most cases, which makes it accessible before you are hired — a meaningful advantage over the Series 7 path.
Solo advisers launching their own RIA. You will need IAR registration, and without a broker-dealer relationship the Series 65 is the route.

Wirehouse and broker-dealer financial advisors. The standard package is SIE + Series 7 + Series 66.
Hybrid advisors. Professionals doing both brokerage and advisory business under one roof.
Anyone already registered with the Series 7 who needs to add advisory capability. Adding the Series 66 is more efficient than adding the Series 63 and Series 65 separately.
Several states waive the Series 65 examination requirement for individuals holding certain professional designations — commonly including CFP®, CFA, ChFC, PFS, and CIC (the Certified Investment Counselor designation, not the insurance CIC).
If you already hold or are pursuing one of these, check your state administrator's rules before you register for an exam you may not need. Waivers are state-specific and not universal.
Our CFP certification courses and CFA training cover two of the most commonly recognized designations. See also financial advisor certifications and designations.
Note that waivers typically apply to the Series 65 only — not the Series 66, which incorporates agent registration material.
Do not study for the Series 7 and Series 66 simultaneously. Pass one, take a short reset, then start the other. Interference between overlapping-but-different material is a genuine cause of failed attempts.

Neither exam registers you. Passing qualifies you; registration happens through a firm or your own RIA filing with the appropriate state or SEC.
You will also pick up ongoing obligations. IARs in states that have adopted the NASAA model are subject to an annual IAR continuing education requirement. See FINRA continuing education requirements and securities licensing by state.
Shorter, and easier for someone who has passed the Series 7. Harder for someone who has not, since it assumes that knowledge.
You can sit for it, but you cannot use it for registration without the Series 7.
No. The 66 includes the agent registration material.
Typically the Series 65, since RIAs generally have no broker-dealer affiliation.
Some states waive the Series 65 for certain designations. Waivers for the Series 66 are far less common. Check your state administrator.
Answer the Series 7 question first, then pick the exam. Everything else is study logistics.
