FINRA Series 23 Guide

Use this guide root when you are preparing for the General Securities Principal Exam Sales Supervisor Module. Series 23 is not a broad substitute for every principal path. It is the narrower route for someone already in the general securities sales supervisor lane who needs the principal module rather than the full Series 24 path.

The current exam configuration uses five functions led by trading and market making, investment banking and research, and general broker-dealer activities. Treat it as a principal-upgrade exam built on an already existing sales-supervision foundation. The strongest candidates keep asking what the principal must supervise beyond the branch-sales lens they already know.

Where Series 23 fits

What this guide is for

Use this guide to confirm route fit, understand the weighted outline, and decide how to use exact practice after the supervision map is clear. Series 23 rewards candidates who already understand sales supervision and now need cleaner principal judgment across trading, research, investment banking, customer supervision, and firm-level activity.
