Answers to Series 24 questions about sponsorship, corequisites, exam length, passing score, principal-registration paths, scope, and study order.
Confirm eligibility, enrollment, and policy details directly with FINRA before scheduling.
Quick links:
Yes. FINRA states candidates for principal-level qualification exams must be associated with and sponsored by a FINRA member firm or other applicable SRO member firm.
FINRA lists 150 items and a 3-hour-45-minute time limit. That length makes pacing and mixed supervisory practice important, especially after the first reading pass.
FINRA lists the passing score as 70. The practical target is stable accuracy across general broker-dealer activity, customer supervision, trading, investment banking, and research, not perfection in one topic block.
Yes. Series 24 does not stand alone. FINRA states the exam works together with the SIE and an eligible representative-level qualification, or Series 16 for the research-principal path. The exact principal registration you receive depends on the corequisite combination.
Not always. Series 7 is the classic path, but FINRA also recognizes other combinations for specific principal lanes. That is why the first real Series 24 question is not “Can I pass the exam?” but “Which principal registration path am I actually trying to support?”
FINRA lists several paths, including:
That is why Series 24 should be studied as a broad supervisory exam rather than as a product exam tied to only one desk or business line.
Series 9 and 10 is the sales-supervisor route. Series 24 is broader. Series 24 can support principal authority across wider broker-dealer supervision depending on the corequisite path, while Series 9 and 10 is centered on supervising sales activities. If your role is mainly branch-sales supervision, that distinction matters before you commit to the harder exam.
Series 24 focuses on principal-level supervision. The exam is built around personnel management, general broker-dealer supervision, customer-account and sales-practice oversight, trading and market-making supervision, and investment-banking or research supervision. It rewards candidates who can identify the supervisory duty, the required approval or escalation step, and the recordkeeping implication.
It is testing whether you can think like a principal across multiple business lines. The stronger answer is usually not the one that best describes a product. It is the one that identifies who must approve something, what must be reviewed, what has to be documented, and what must be escalated when facts go wrong.
Series 24 usually fits people moving into broader principal or supervisory roles across the broker-dealer rather than narrow product-only supervision. If your role is limited to options, investment company and variable products, investment banking, private offerings, or another specialized lane, another principal path may be more appropriate.
The most common mistake is answering like a representative instead of a principal. A representative-level answer often focuses on the product or the transaction. A stronger Series 24 answer usually focuses on supervision, approvals, red flags, exception handling, and documented follow-up.
The general supervision block deserves the most time because it carries the most weight and touches the broadest range of day-to-day supervisory facts. After that, customer-account supervision and trading or market-making supervision usually give the best return on study time.
Start with Function 2 because it carries the most weight and touches the broadest day-to-day supervisory issues. Then move through customer supervision, trading and market-making oversight, and finally the personnel or registration topics that are easier once the broad supervisory framework is already stable.
You should know the big rule families well enough to recognize what area of supervision a question belongs to, but raw rule-number memorization is not the center of the exam. Series 24 pays more for recognizing the supervisory duty and the right follow-up step than for reciting isolated citations.
Use a drill-first approach for each supervisory function, then switch to mixed timed sets. Series 24 rewards candidates who can move quickly between unrelated business areas without losing the supervisory frame.
Write a one-line reason for each miss, but classify it as one of three problems:
That makes retesting much more useful than simply re-reading the explanation.
Switch once you can usually identify the correct business area quickly. Series 24 becomes much more realistic when customer-account, trading, investment-banking, and personnel issues are mixed together, because that is when weak supervisory instincts become obvious.
FINRA retake waiting periods can depend on attempt count and exam type. Confirm the current rule before rescheduling rather than relying on memory or older prep notes.
