Series 63 vs 65 vs 66: Which Exam Do You Need?

If you’re searching Series 63 vs 65 vs 66, you need a clear answer: which state exam matches the job you want? These three are NASAA exams (North American Securities Administrators Association — state securities regulators). FINRA (the Financial Industry Regulatory Authority) administers them. Below: who each exam is for, official formats, co-requisites, how to choose, and five practice questions.

Quick map: who each exam is for

• Series 63 — Uniform Securities Agent State Law Exam. State-law test for broker-dealer agents (people who sell securities through a broker-dealer).
• Series 65 — Uniform Investment Adviser Law Exam. For investment adviser representatives (IARs) who give investment advice for a fee.
• Series 66 — Uniform Combined State Law Exam. Combines 63 + 65 material. Passing qualifies you as if you had passed both — typically for dually registered people (broker-dealer agent and IAR).

Exam formats side by side

• Series 63: 60 scored + 5 unscored pretest questions. 75 minutes. Pass: at least 43 of 60 scored correct. Fee $147. FINRA lists no corequisite.
• Series 65: 130 scored + 10 unscored. 180 minutes. Pass: at least 92 of 130 scored correct. Fee $187. FINRA lists no corequisite.
• Series 66: 100 scored + 10 unscored. 150 minutes. Pass: at least 73 of 100 scored correct. Fee $177. FINRA lists corequisites as the SIE + Series 7.

All three are multiple choice, with results on completion. Once enrolled, FINRA opens a 120-day window to schedule. You do not need a firm sponsor to sit — unsponsored candidates can enroll through FINRA’s Test Enrollment Services System (TESS). Firm-affiliated candidates usually enroll via Form U4.

Prerequisites, co-requisites, and licensing

Taking an exam and registering with a state are different steps.

Series 63 and Series 65: FINRA lists no exam corequisite. You can sit without the SIE (Securities Industry Essentials) or Series 7. Most states still require FINRA exams (often SIE plus a representative exam such as the Series 7) before licensing a broker-dealer agent — check your state.

Series 66: FINRA says there is no prerequisite to take it, but the Series 7 is a co-requisite, and FINRA’s at-a-glance box lists SIE + Series 7. NASAA adds that registering through the Series 66 requires a valid SIE and Series 7. You may take the exams in any order; both must be passed when you seek state registration.

Passing is not a license. NASAA states that passing is normally a prerequisite for state licensing. States may still require Form U4, a background check, bonding, and fees before you can do business.

How the content differs

NASAA’s outlines (effective June 12, 2023) weight scored questions differently:

• Series 63: almost entirely state law and ethics for agents — ethical practices (25%), communication with customers (20%), plus broker-dealer/agent regulation, securities registration, and remedies.
• Series 65: economics (15%), investment vehicles (25%), client recommendations (30%), and laws/ethics (30%). Full IAR exam for people who may not hold the Series 7.
• Series 66: laws/ethics 45%, client strategies 30%, vehicles 17%, economics 8%. Shorter than the Series 65 (100 vs 130 scored) because SIE and Series 7 items are generally not retested.

How to choose: 63, 65, or 66

• Broker-dealer sales only: FINRA exams your firm requires (often SIE + Series 7), then the Series 63 for state agent registration in most states.
• IAR only: the Series 65. You do not need the Series 7 the way you do for the 66. Some states accept designations such as CFP, CFA, ChFC, PFS, or CIMA instead of the Series 65 — confirm with your state. Those designations do not waive the Series 66.
• Dual registration (BD agent + IAR): many take the Series 66 with a valid SIE and Series 7 instead of both the 63 and 65. If you already have a valid Series 63 plus SIE and Series 7 and only need IAR qualification, NASAA says either the 65 or the 66 can work — ask your state.

Study tips that match the formats

• Match the clock: practice the 63 under 75 minutes, the 65 under 180, the 66 under 150.
• Know the pass counts: Series 65 is 92 of 130 — not a fuzzy 70% percentage (NASAA). Series 63 is 43/60; Series 66 is 73/100.
• Weight study to the outline: ethics/communications on the 63; laws/ethics plus client recommendations on the 65 and 66.
• Plan retakes: 30 days after a first or second fail; 180 days after a third fail (and each later fail) within a two-year window. Waiting periods are exam-specific. For enrollments opened on or after January 4, 2027, NASAA says the wait after a third fail drops to 60 days.
