Series 63 vs 65 vs 66: Which Exam Do You Need?

Compare NASAA Series 63, Series 65, and Series 66 routes and choose the right Securities Prep practice page.

Series 63, Series 65, and Series 66 are state-law routes, but they do not serve the same role. Use this page to separate agent law, investment adviser representative qualification, and the combined state-law route usually paired with Series 7.

Open the matching Securities Prep practice route for timed mocks, topic drills, progress tracking, explanations, and the full question bank.

How to choose

If your registration path includes Series 7 and state law, compare Series 66 first. If you are focused on adviser registration without Series 7, Series 65 is usually the more relevant page. Series 63 is narrower and focuses on agent state-law obligations.
