Series 7 vs Series 66 (2026): Differences & Which First

Most exam comparisons end with "pick one." This one doesn't. The Series 7 and the Series 66 are usually taken by the same person, because FINRA lists the Series 7 as a corequisite of the Series 66: the Series 7 is the FINRA license to sell securities, and the Series 66 is the state-law exam that — paired with a valid Series 7 — supports registration as both a securities agent and an investment adviser representative. If you searched "Series 7 vs Series 66," the useful answers are what each exam actually qualifies you for, how different they are on test day (125 questions and 225 minutes versus 100 and 150), and which order to take them in. Here are all three, with 2026 numbers checked against the official FINRA and NASAA pages.

What each exam is for

The Series 7 is FINRA's General Securities Representative Qualification Examination. FINRA says it assesses the competency of an entry-level registered representative, and passing it — together with the Securities Industry Essentials (SIE) exam — earns the General Securities Representative registration. That registration is broad: FINRA describes it as qualifying you for the solicitation, purchase, and sale of all securities products, including corporate securities, municipal fund securities, options, direct participation programs, investment company products, and variable contracts. In plain terms, the Series 7 is the license to sell securities.

The Series 66 is the Uniform Combined State Law Examination — written by NASAA (the North American Securities Administrators Association) and administered on its behalf by FINRA. "Combined" is the load-bearing word: NASAA states that passing the Series 66 qualifies an individual as if they had passed both the Series 63 (the state-law test for broker-dealer representatives) and the Series 65 (the investment adviser law exam). One sitting covers both state-law qualifications. The catch is that the Series 66 doesn't work alone: NASAA is explicit that to register as an investment adviser representative based on the Series 66, you must also have passed the FINRA Series 7, and that Series 7 must still be valid.

Format, length, and cost: the concrete differences

Question counts and time limits

The Series 7 is much the bigger test day: 125 scored multiple-choice questions with 3 hours and 45 minutes — 225 minutes — on the clock. The Series 66 runs 100 scored questions plus 10 unscored pretest questions, with 150 minutes allowed. The pretest questions on the Series 66 don't count toward your score, but they aren't marked, so treat every question as if it's live.

Passing standard

The Series 7 passing score is 72%. The Series 66 asks slightly more: FINRA states you must answer at least 73 of the 100 scored questions correctly — 73%. Each exam has a fixed passing bar, and the one-point difference between them is not a reason to fear one over the other; the content and stakes should drive your preparation, not the cutoff.

Fees

As of 2026, FINRA's exam pages list the Series 7 at $395 and the Series 66 at $177. Because you'll likely need both — plus the SIE — treat these as line items in one licensing budget rather than a price comparison, and ask whether your sponsoring firm covers exam fees before you pay out of pocket.

Prerequisites and sequencing

The Series 7 carries two structural requirements. First, the SIE is a corequisite: FINRA states candidates must pass both the SIE and the Series 7 to obtain the General Securities Representative registration. Second, sponsorship: to be eligible for the Series 7, you must be associated with and sponsored by a FINRA member firm or another applicable self-regulatory-organization member firm. You can't self-schedule it from outside the industry — the firm comes first.

The Series 66, by contrast, has no prerequisite exam. But the Series 7 is its corequisite, and that distinction matters: a corequisite doesn't dictate order, only completeness. You may sit the Series 66 before or after the Series 7; the registrations it supports simply don't take effect until the Series 7 side is also passed and valid.

So what order makes sense? A reasonable default is SIE first, then Series 7, then Series 66. The Series 7 is the heavier lift — 25 more scored questions and an extra 75 minutes — and it's the exam your sponsoring firm needs you to clear to work as a registered representative, so it usually deserves your freshest study push. The Series 66's shorter, law-focused sitting then rounds out the state-law side. But if your firm's onboarding calendar schedules the 66 first, nothing in the rules stops that.

The verdict, by situation

• You're joining a broker-dealer whose reps also give advice: plan on both exams. The Series 7 is your securities license; the Series 66, paired with it, adds state-law qualification as both an agent and an investment adviser representative. They're corequisites, not competitors.
• You only want to sell securities: the Series 7 (with the SIE) is your core exam. Whether you also need a state-law exam — and whether that's the 66 or the shorter Series 63 — depends on your firm and the states you'll operate in, so confirm with your compliance team.
• You want to give investment advice but will never hold a Series 7: the Series 66 route is closed to you, because NASAA requires a valid Series 7 alongside it for adviser-representative registration. Look at the Series 65 instead — it's the standalone adviser-law exam.
• You've passed the Series 7 and are weighing the 66 against taking the 63 and 65 separately: NASAA treats a Series 66 pass as if you'd passed both — one 100-question, $177 sitting instead of two exams and two fees.

Whichever sequence your firm sets, the Series 7 is the tallest hurdle in it — the longest sitting, the broadest content, and the exam everything else is anchored to.
