Do you need the Series 7 before the Series 66?
Verified from NASAA, last checked 2026-07-02. Quick answer below, then the full breakdown.
No, order does not matter, but you need both. The Series 7 is a co-requisite: you can take the Series 66 before or after it, and your dual registration as an agent and investment adviser representative only becomes effective once you have passed both exams.
The Series 7 is a co-requisite for the Series 66, not a prerequisite:
- You may take the two exams in either order
- Your registration as a dually-licensed agent and investment adviser representative only activates once both are passed
- No SIE requirement is added on top of the Series 66 itself (the SIE belongs to the Series 7 track)
Most candidates take the Series 7 first because firms sequence it that way, and because the Series 66 assumes the product knowledge the 7 teaches: NASAA leaves securities-product depth out of the 66 precisely because the 7 covers it.
If you do not plan to carry a Series 7 at all, the Series 66 is the wrong exam: the Series 65 covers the standalone investment adviser path.
