Series 65 vs Series 66: which one do you need?

One question decides it: do you have, or are you getting, the Series 7? If yes, take the 66. If no, take the 65. Everything else on this page is detail.

Which is harder?

For a Series 7 holder, the 66 is the easier path: it's shorter and skips everything the 7 already covered. Taken cold, the 65 is the broader exam but has a slightly lower pass line. What the two share is where people fail: the Uniform Securities Act detail in the law sections, and pacing. Both give you roughly 83 to 90 seconds a question. See how hard is the Series 65.

Can you take the 66 without the 7?

You can sit the exam, but you can't register on it. The Series 7 is a corequisite for the 66 registration, so a passed 66 without the 7 licenses you for nothing until the 7 is done. If the 7 isn't in your plan, the 66 is the wrong exam.

After you pass

Either result is valid for two years for registration purposes: you must be registered with a state (as an IAR, via Form U4 through a firm) within two years of passing or the exam has to be retaken. Some states also waive the exam for holders of the CFP, CFA, ChFC, PFS or CIC designations; check your state's rules before enrolling.

Common questions

Do I need the Series 7 for the Series 65?

No. The Series 65 has no prerequisites and no sponsor requirement. You enroll yourself through FINRA's Form U10.

Is the Series 66 easier than the Series 65?

For someone who already holds the Series 7, usually yes: it's shorter and assumes the product knowledge the 7 tested. Taken without that background, the 65 is broader but has a lower pass line.

Does the Series 66 replace the Series 63 and 65?

Yes. Passing the 66, together with the Series 7, satisfies both the state agent registration (63) and the state investment adviser representative registration (65).

Can I take the Series 65 and later add the 66?

You can, but you rarely need to. If you later join a broker-dealer and get the 7, the 63 is usually enough alongside your existing 65.

How long are Series 65 and 66 results valid?

Two years to become registered in at least one state after passing; after that the exam must be retaken unless a state grants a waiver.
