Does the Series 66 replace the Series 63 and Series 65?
Verified from NASAA, last checked 2026-07-02. Quick answer below, then the full breakdown.
Yes, for candidates who carry a Series 7. The Series 66 combines the Series 63 (state agent law) and Series 65 (investment adviser law) into one exam. Without a Series 7, the 66 is unavailable as a path and the separate exams (or the 65 alone) are the alternative.
The Series 66 is literally the Uniform Combined State Law Examination: NASAA built it to fold the Series 63 and Series 65 into a single test for dually-registered reps.
The decision comes down to the Series 7:
- You have (or will get) the Series 7: take the 66. One exam, one fee, both registrations.
- No Series 7, agent registration only: the Series 63 is the fit.
- No Series 7, adviser path only (fee-only RIA/IAR): the Series 65 stands alone.
One nuance: the 66's law content is somewhat lighter than the 63 + 65 combined, because NASAA assumes the Series 7 covers your product knowledge. That is why the 7 is a hard co-requisite.
