High-yield Series 23 cheat sheet for the FINRA General Securities Principal Sales Supervisor Module: exam facts, business-line recognition, trading supervision, banking and research conflicts, and principal-control traps.
Series 23 is “principal extension.” Most questions ask what a principal should supervise, restrict, approve, document, or escalate once basic sales-supervision knowledge already exists.
Quick links:
| Route | Use when… |
|---|---|
| Series 23 | the candidate is already in the general securities sales supervisor path and needs the principal module |
| Series 24 | the candidate needs the broader General Securities Principal exam directly |
| Series 9/10 | the role is sales supervision rather than the broader principal module |
| Business line | What to ask in a vignette |
|---|---|
| registration and personnel | What filing, status, office, supervision, or termination control is required? |
| general broker-dealer activity | What written supervisory procedure, approval, reporting, or recordkeeping control applies? |
| customer activity | What account, communication, recommendation, complaint, or institutional-customer control is missing? |
| trading and market making | What restriction, surveillance, exception review, or market-integrity control is required? |
| investment banking and research | What conflict, barrier, disclosure, approval, or research-supervision control is required? |
| If the question feels like… | First bucket | Strongest first instinct |
|---|---|---|
| sales-supervision fact pattern with broader implications | customer or general activity | ask what the principal must do beyond the rep or branch fix |
| desk issue or market-making problem | trading | restrict, review, escalate, and document |
| offering or research conflict issue | investment banking / research | separate functions, control access, approve carefully |
| rep status or office problem | registration / personnel | verify status, restriction, filing, and supervision |
| If the stem shows… | Think first about… | Usually strongest next move |
|---|---|---|
| issue that a branch supervisor noticed but did not resolve | principal responsibility | broaden the review and document the decision path |
| trading-control exception | market supervision | investigate, restrict if needed, retain evidence |
| banking or research pressure | conflicts and approvals | enforce barriers and formal review |
| customer issue spanning multiple controls | customer supervision | look at file quality, communication, recommendation basis, and escalation |
