To get a Series 66 license, you enroll for the Uniform Combined State Law Examination through FINRA, pass that 100-scored-question test, pass the Securities Industry Essentials (SIE) exam and the Series 7, and complete state registration through a sponsoring broker-dealer or investment advisory firm. The exam itself has no prerequisites, but your registration won’t activate until all three exams are on your record and at least one state has approved you. Start to finish, expect a few weeks if your background check and state filings move without complications.
What the License Covers
The Series 66 qualifies you to work as both a securities agent and an investment adviser representative. Passing it is equivalent to passing the Series 63 and Series 65 as separate exams, and NASAA created the combined test so professionals doing both jobs wouldn’t have to sit for two.1North American Securities Administrators Association. Exam FAQs
If you only plan to sell securities, the Series 63 alone (with the SIE and Series 7) is enough. If you plan to give investment advice but never sell securities through a broker-dealer, the Series 65 stands on its own and doesn’t require the Series 7. The Series 66 fits candidates who intend to do both, which is common at firms that manage client portfolios and execute trades.
One thing to know for later: FINRA’s Central Registration Depository doesn’t store the Series 66 as a single credential. It splits into separate Series 63 and Series 65 exam credits, each with its own validity tied to your registration history.1North American Securities Administrators Association. Exam FAQs That matters if you change firms or your registration lapses.
Prerequisites and Co-Requisites
p>Nothing prevents you from sitting for the Series 66. There is no degree requirement, no experience requirement, and no prior license required to take the exam.2FINRA. Series 66 – Uniform Combined State Law Exam You can take it before the Series 7 if you want.
Passing alone, though, won’t get you registered. The Series 7 is a co-requisite, meaning no state will approve your registration until you’ve passed it.3North American Securities Administrators Association. Series 66 Exam Content Outline The SIE is also required: FINRA needs a valid SIE plus the Series 7 Top-Off exam (which together constitute passing the Series 7) before your Series 66 registration can take effect.4FINRA. Co-requisites for Qualification Exams Anyone can take the SIE without firm sponsorship, so many candidates knock it out while job searching.
How to Enroll
With a Sponsoring Firm
Most candidates are sponsored by a broker-dealer or investment adviser. Your firm files Form U4, the Uniform Application for Securities Industry Registration or Transfer, through the FINRA Gateway.5FINRA. Form U4 The U4 becomes your permanent record in the industry. It asks for your legal name, Social Security number, a ten-year employment history, and a five-year residential history, along with disclosures covering criminal convictions, regulatory actions, bankruptcies, and unsatisfied judgments. Take those disclosure questions seriously. Omissions or misrepresentations can delay your registration, generate fines against your firm, or end a career before it starts.
Without a Sponsor
You can still take the exam without a firm behind you by enrolling independently through FINRA’s Test Enrollment Services System (TESS). You create a profile, enter your information, and pay the $177 exam fee to open a testing window.3North American Securities Administrators Association. Series 66 Exam Content Outline Passing without a sponsor gets you exam credit, not a license. You still need a firm to complete state registration.
The 120-Day Window
Once enrollment is processed, FINRA opens a 120-day window for you to sit for the exam, starting the day after the enrollment request is submitted.6FINRA. Frequently Asked Questions About Qualifications in CRD Miss it and you re-enroll and pay again.

What’s on the Exam
The Series 66 has 110 multiple-choice questions, 100 of which are scored. The other 10 are unscored experimental items placed randomly, so treat every question as if it counts. You have 150 minutes, and you need at least 73 of the 100 scored questions correct to pass.2FINRA. Series 66 – Uniform Combined State Law Exam
Content weights break down into four sections:9North American Securities Administrators Association. Series 66 Test Specifications
- Laws, regulations, and guidelines, including prohibited business practices: 45%. This is where most of your study time should go, and it’s what separates the Series 66 from the Series 7.
- Client investment recommendations and strategies: 30%.
- Investment vehicle characteristics: 17%.
- Economic factors and business information: 8%.
The exam is shorter than the standalone Series 65 (100 scored questions versus 130) because topics already covered by the SIE and Series 7 are generally excluded.1North American Securities Administrators Association. Exam FAQs
If You Fail
After a first failed attempt, you must wait 30 days to retake. The same 30-day wait applies after a second failure. On a third failure, the wait jumps to 180 days, and that longer wait applies to every subsequent attempt.10North American Securities Administrators Association. NASAA Implements Waiting Period for Those Who Fail Exams Each retake needs a new $177 enrollment and starts a new 120-day window.
Getting Registered With a State
Passing the exam is not the license. Each state must separately approve your registration before you can do business there.3North American Securities Administrators Association. Series 66 Exam Content Outline Your sponsoring firm handles the state filings and pays state-specific fees, which range from under $50 to over $200 and are typically annual.
If you passed the Series 66 but aren’t currently employed by a registered firm, your exam credit is valid for two years from the pass date. Once a registration is terminated after you leave a firm, exam credit remains valid for two years from the termination date.11FINRA. Exam Credit and Exam Validity Let those windows close without an active registration and you’ll have to retake the exam.
Keeping the License Active
Series 66 holders face two layers of continuing education. A growing number of states require investment adviser representatives to complete 12 IAR CE credits each year: 6 in products and practices and 6 in ethics and professional responsibility, with each credit representing at least 50 minutes of instruction. You can’t carry excess credits forward.12North American Securities Administrators Association. IAR Continuing Education FAQ As of 2026, roughly 25 jurisdictions have adopted the requirement, including California, Florida, Illinois, and New Jersey, with more states adding it regularly.13North American Securities Administrators Association. IAR CE Map Miss the annual deadline and your status changes to “CE Inactive”; miss two consecutive years and your registration fails to renew, and you must complete all deficient credits before re-registering.
