The Series 24 General Securities Principal Exam is moderately challenging—it requires solid grasp of broker-dealer supervision, but candidates who pass prerequisite exams and study systematically typically succeed. You need to score 70 percent to pass, and the exam contains 150 questions delivered across 225 minutes, giving you roughly 90 seconds per item with room for review. The main difficulty spike comes from balancing breadth of regulatory knowledge with depth in compliance oversight and firm operations. For most candidates moving from a representative role, the Series 24 represents a meaningful step up in scope and accountability.
What Is the Series 24?
The Series 24 qualifies you as a General Securities Principal—a supervisory role overseeing most broker-dealer activities. Unlike representative licenses (Series 7, Series 6), the Series 24 focuses on the firm's supervisory systems, compliance policies, and risk management rather than client-facing sales. If you're moving into management or compliance, or if your firm requires principal-level oversight authority, the Series 24 opens that pathway. The exam is also called the Qualifications Exam for General Securities Principal. Supervisors holding this license bear responsibility for reviewing and approving customer transactions, supervising registered representatives, and ensuring the firm meets regulatory obligations.
Prerequisites and Enrollment
Before you can sit for the Series 24, you must clear two hurdles. First, candidates must pass the Securities Industry Essentials (SIE) exam and an appropriate representative-level qualification exam such as the Series 7 before taking the Series 24. The SIE is your foundation—it covers market structure, product knowledge, and core regulatory principles. The SIE consists of 75 scored questions and costs $100; a passing SIE result remains valid for 4 years, so you have a reasonable window to pursue the Series 24 if you pass early. Many candidates complete the SIE and Series 7 in the same year, then apply for the Series 24 within 12 to 24 months once they're ready to step into a principal role.
Second, enrollment requires sponsorship by an eligible regulatory authority; self-enrollment is not available for the Series 24. Your broker-dealer submits sponsorship, typically via Form U4, on your behalf. Once sponsored, FINRA posts a 120-day window in which the exam must be taken—this is your scheduling deadline, so plan ahead. The enrollment fee for the Series 24 itself is $235. Combined with the SIE fee, the total cost of regulatory exams required before Series 24 eligibility is modest; the bigger investment is your study time and effort.
Exam Structure and Content
The Series 24 tests two primary supervisory functions across 150 multiple-choice items. The exam spans 3 hours and 45 minutes, so time pressure is moderate if you know the material; rushing is the real risk. The content breaks into two major areas: Function 2 covers supervision of general broker-dealer operations—compliance systems, capital requirements, and supervisory oversight—and contains 45 items. Function 3 addresses supervision of retail and institutional customer-related activities, including sales practices, suitability rules, and customer protection requirements, with 32 items. The remaining questions test supporting regulatory knowledge woven across both functions. Topics within these functions span anti-money laundering (AML), know-your-customer (KYC) protocols, sales practice standards, order routing and execution, customer complaint handling, and registration procedures.
Scheduling and Administrative Requirements
Once enrolled, you schedule your exam appointment with Prometric, FINRA's test delivery vendor. You can test at a local test center or sit for the exam online—both options are available. The online proctored format has become common and eliminates travel logistics. If you need to reschedule or cancel, act early: you must do so a minimum of 10 business days in advance to avoid any fees. If you reschedule or cancel within two business days, or fail to appear, you'll pay a rescheduling or no-show fee equal to the full exam cost. This penalty structure is why confirming your exam date well in advance and blocking out adequate study time matters.
Passing the Exam
The passing threshold is 70 percent—you need to answer at least 105 of the 150 questions correctly. Most candidates find this attainable if they master core supervisory concepts: firm compliance programs, anti-money laundering (AML) procedures, supervision of sales practices, capital rules, and registration requirements. The exam emphasizes application over trivia. Expect scenarios testing your judgment on whether a firm's practice meets regulatory standards or whether a supervisor's action complies with FINRA rules. These scenario-based questions reward deeper understanding.
Study Timeline and Difficulty
The Series 24 typically requires 50 to 80 hours of focused study for candidates who've already passed the Series 7 or 6. If you're fresh from the Series 7, many concepts overlap—customer protection rules, suitability, and sales practice oversight thread through both exams. However, the Series 24 adds layers on compliance infrastructure and firm-level controls that representative-level exams don't emphasize. Most candidates allow 6 to 10 weeks for preparation, particularly if they're balancing study with full-time work. The difficulty lies not in memorizing isolated facts but in integrating supervision principles across complex regulatory scenarios.
Common Study Challenges
Candidates often struggle with three specific areas. First, the interconnection between AML rules, KYC requirements, and customer protection—each topic appears separately in the curriculum, but the exam blends them in scenario form. Second, understanding the supervisory escalation chain—when a compliance issue should be reported to a principal, when to FINRA, and when to external authorities. Third, the nuances of record-keeping and documentation, which seem tedious but carry significant weight in exam questions because regulators rely on these records to monitor the industry.

Bottom Line
The Series 24 sits at a moderate difficulty level—harder than representative exams because it demands supervisory judgment, but manageable for anyone who has already passed the Series 7 or equivalent and commits to structured study. The time allocation is fair, the passing score is standard across FINRA exams, and the prerequisites ensure you have foundational knowledge. Success comes down to mastering firm compliance, supervisory responsibilities, and regulatory application rather than raw memorization. If your broker-dealer is sponsoring you for this exam, treat it as a critical gate to career advancement.
