What Is on the Series 24 Exam?

The Series 24 exam covers five major job functions of a general securities principal: Supervision of Registration of the Broker-Dealer and Personnel Management Activities, Supervision of General Broker-Dealer Activities, Supervision of Retail and Institutional Customer-Related Activities, Supervision of Trading and Market Making Activities, and Supervision of Investment Banking and Research.[2]

Our full practice test is weighted across these five functions to mirror the structure of the real exam. Each full simulation draws a fresh, function-weighted set from the question pool:

After each full exam, your results show a per-function breakdown so you know exactly where to focus — most candidates need the most reps on the supervision and trading and market-making rules.

What Are the Prerequisites for the Series 24?

The Series 24 has no education or experience requirement, but you must be associated with and sponsored by a FINRA member firm.[1] The Series 24 is corequisite-based: General Securities Principal status requires passing the SIE and the Series 7 exams.

[4][5] Other representative-level corequisites — such as the Series 57, 79, 82, or 86/87 — lead to narrower principal categories. Your specific principal authority depends on which representative registrations you hold alongside the Series 24.

How Do You Register for the Series 24?

You register for the Series 24 through your sponsoring FINRA member firm, which enrolls you by filing a Form U4 and an exam request through FINRA’s CRD / FinPro system.

[1] Once enrolled, you receive a 120-day window to schedule and take the exam through Prometric — at a physical test center or via online proctoring where available. The exam fee is $235.

Review FINRA’s official Series 24 page and content outline for current enrollment steps and testing accommodations before your appointment.

What Is the Passing Score for the Series 24?

The passing score for the Series 24 is 70%, meaning you must answer at least 105 of the 150 scored questions correctly.[2] Only 150 of the 160 questions count toward your score; the other 10 are unscored pretest items distributed throughout the exam without identification.

The Series 24 is scored on your overall performance across all five functions. Results are reported as pass or fail with diagnostic information by function, but your overall score determines the result.

How Hard Is the Series 24?

The Series 24 is considered one of the more demanding FINRA principal exams.[3] FINRA does not publish official pass-rate statistics, but industry training providers commonly report first-time pass rates in the rough range of 60 to 70%. The difficulty comes from breadth, the volume of FINRA and SEC rules a principal is responsible for, and the higher-order supervisory framing — many items ask what a principal must do to maintain a reasonable supervisory system, not simple recall of a rule.

The takeaway: build on your Series 7 foundation, focus on supervisory systems and written supervisory procedures, and practice applying rules to fact patterns until you’re consistently scoring above 70% on full-length practice before you book your exam date.

What to Expect on Exam Day

Arrive at your Prometric test center early to check in — bring a valid, unexpired government-issued photo ID whose name matches your enrollment.[1] You’ll store phones and personal items in a locker; no notes are allowed, but you’re given erasable note materials and an on-screen calculator.

After a short tutorial you have 3 hours 45 minutes to answer 160 multiple-choice questions. If you test via online proctoring, expect a similar room scan and ID check. FINRA posts your result at the end of the session and reports it to your firm through the CRD system.

Having simulated the full timing with practice tests makes that long clock feel routine.

How to Use This Series 24 Practice Test
