Series 65 vs Series 66: which exam you need, and where the 63 and 7 fit
Take the Series 65 (Uniform Investment Adviser Law Examination) if you want to give investment advice for a fee without a broker-dealer license. Take the Series 66 only if you also hold or will take the Series 7, because the 7 is a corequisite of the 66. The 66 combines the state-law ground of the 63 and the 65, so a 7 + 66 holder can register both as a broker-dealer agent and as an investment adviser representative (IAR).
The short answer
All three state-law exams are NASAA exams. NASAA develops them and FINRA administers them, and you sit them at Prometric test centers. The Series 7 is FINRA’s own exam. None of these exams is a license by itself: after a pass, a firm files your Form U4 and the state registers you. For the 65 that registration has to happen within 2 years of the pass, and the license page walks through each form.

| Full name | Uniform Investment Adviser Law Examination | Uniform Combined State Law Examination | Uniform Securities Agent State Law Examination | General Securities Representative exam |
| Developed by | NASAA | NASAA | NASAA | FINRA |
| What a pass leads to | Registration as an investment adviser representative | Registration as both a broker-dealer agent and an IAR, once paired with the Series 7 | Registration as a securities agent under state law | Selling all securities products for a broker-dealer |
| Needs anything else? | No: no prerequisite and no firm sponsor | The Series 7 is a corequisite | No prerequisite | The SIE is a corequisite, and a member firm must sponsor you |
| Questions | 130 scored + 10 unscored | 100 scored + 10 unscored | 60 scored + 5 unscored | 125 scored + 10 unscored |
| Time | 180 minutes | 150 minutes | 75 minutes | 3 hours 45 minutes |
| To pass | 92 of the 130 scored | 73 of the 100 scored | 43 of the 60 scored | See FINRA’s Series 7 page |
| Waived by a designation? | In most states, for a current CFP, CFA, ChFC, PFS or CIMA (check yours) | Never | — | — |
Format and corequisites are from FINRA’s pages for the Series 65, Series 66, Series 63 and Series 7, checked Oct 2026. The Series 65 fee is currently $187 per FINRA (checked Oct 2026).
The table shows the main point: the 65 is the only one of the four that leads to IAR registration with nothing attached. The 66 does the same job only next to the 7, and the 7 needs a sponsoring firm and the SIE. So the 7 + 66 pair is a broker-dealer route, and the 65 is a route for people outside a broker-dealer.
When the Series 65 alone is enough
If your income will be advisory fees (a percentage of assets, a flat planning fee or an hourly rate) and not commissions on securities sales, the 65 covers the exam side. You can enroll yourself on Form U10 without a firm, and you have an enrollment window, currently 120 days, to sit it.
Fee-only adviser opening a practice
You plan to manage client money for an annual fee and will not join a broker-dealer. No firm will sponsor a Series 7, and you do not need one.
Series 65
Planner with a CFP
You already hold the CFP and want to add investment advice. Most states waive the Series 65 for a current CFP, CFA, ChFC, PFS or CIMA. Check which list your state uses; the license sheet has the 2024 change.
Check your state’s waiver before you study
Analyst moving to an RIA
An advisory firm hires you to meet clients and recommend portfolios. It is not a broker-dealer, and nobody there earns commissions.
Series 65; the firm files your U4
The 65 asks more in return. It is longer than the 66 and spends 91 of its 130 scored questions on economics, investment vehicles and client recommendations, the material a 66 candidate has usually already studied for the Series 7. The exam page breaks down all four sections.
When the 7 + 66 route makes sense
The 66 suits someone inside a broker-dealer who will also give advice for a fee, usually at a firm registered on both sides. You need the Series 7 for the sales side whatever happens, so one 110-question state-law exam replaces two (the 63 and the 65).
Broker who also charges advisory fees
Your firm sponsors your Series 7 and SIE, and you will run fee-based accounts as well as commission business.
Series 7 + SIE + Series 66
Agent only
You will sell securities on commission and give no advice for a separate fee. The adviser exam adds nothing to your job.
Series 7 + SIE + Series 63; no 65 or 66
Already holding the 7 and the 63
You passed the 63 years ago and now want to add advisory accounts. The 66 would test the 63 law again.
Add the Series 65
The order also matters if you change course later. A 66 pass leads to IAR registration only when you also have the Series 7, so someone who leaves the broker-dealer path before passing the 7 is left with a 66 that cannot be used, and has to start again with the 65.
Which is harder?
No current pass rate is published for either exam, so any “harder” claim with a percentage attached comes from a course seller. You can compare the structure, though:
38
scored misses the 65 allows
92 of 130 to pass
27
scored misses the 66 allows
73 of 100 to pass
77 s
per question on the 65
140 questions, 180 minutes
82 s
per question on the 66
110 questions, 150 minutes
The 66 is shorter and a little less rushed, but it leaves less room for misses, and because it is paired with the Series 7, most candidates reach it having already studied the products for that exam. The 65 gives you more room for misses and more time overall, and teaches the products itself: Sections I to III are 70% of the outline, and Section IV, the law, is the other 30%. If you have just passed the 7, the 66 will usually feel lighter. If you are coming from outside the industry, the 65 is the one built for you, and the question is how many weeks you give it. The study plan sizes those weeks.
Against the Series 7 the comparison is about scope more than difficulty. The 7 runs 3 hours 45 minutes over every product a general securities representative can sell, including options and municipal fund securities, and it needs a sponsoring firm. The 65 covers less sales mechanics and more advice: client profiles, tax, retirement plans and an adviser’s duties under state and federal law.
Whichever exam you choose, the fastest way to see where you stand is a set of questions answered cold. The 60-question practice test follows the 65’s section weights.
FAQ
What is the difference between a Series 65 and Series 66?
The Series 65 leads to registration as an investment adviser representative by itself. The Series 66 combines the state-law content of the 63 and the 65 and leads to registration as both a broker-dealer agent and an IAR, but only together with the Series 7, its corequisite. The 65 is 140 questions in 180 minutes; the 66 is 110 in 150.
Is the Series 65 or 66 exam harder?
No current pass rates are published, so there is no factual answer by numbers. The 65 is longer and tests investment products and client strategy itself, and it allows 38 misses out of 130 scored questions. The 66 is shorter and allows 27 misses out of 100, but it assumes you already know the products from the Series 7.
Do I need Series 65 if I have 66?
Not if you also hold the Series 7: together, the 7 and the 66 lead to IAR registration. Without the Series 7, the 66 cannot be used for registration, and the Series 65 is the route that stands alone.
Do I need Series 66 if I have 63 and 65?
No. The 63 covers the state-law side for a broker-dealer agent and the 65 covers the investment adviser side, and the 66 combines exactly those two. Taking it as well would repeat ground you have already passed.
Is the Series 65 exam harder than the Series 7?
They test different things. The 7 covers the full range of securities products and sales over 3 hours 45 minutes, and it needs a sponsoring firm and the SIE. The 65 has no prerequisite and focuses on advice, tax, retirement plans and law: you need 92 of 130 scored questions in 180 minutes. Your background decides which one is harder for you.
