Series 65 vs Series 66

The Series 65 is a standalone exam for investment adviser representatives. The Series 66 combines the Series 63 (state agent law) and Series 65 (adviser law) into one exam - but requires the Series 7 as a prerequisite.

What Each Exam Allows You To Do

Series 65

  • Work as an Investment Adviser Representative (IAR)
  • Provide investment advice for a fee
  • Manage client portfolios at an RIA
  • No securities selling authority

Series 66

  • Everything Series 65 allows, PLUS:
  • Register as a securities agent (like Series 63)
  • Work as both broker and adviser
  • Dual registration in one exam

Who Should Take Each Exam?

Take the Series 65 if you...

  • Fee-only financial advisors
  • Those working at RIAs exclusively
  • CFP candidates needing licensure
  • Career changers (no SIE required)

Take the Series 66 if you...

  • Series 7 holders who also want adviser registration
  • Full-service financial advisors
  • Those at dual-registered firms (BD + RIA)
  • Wirehouse and hybrid advisors

Which Should You Take First?

If you don't have the Series 7 and only want to be an investment adviser (no securities sales), take the Series 65. If you already have or plan to get the Series 7, take the Series 66 - it's more efficient than taking the Series 63 and Series 65 separately.

Frequently Asked Questions

QCan I take the Series 66 without the Series 7?

No. The Series 66 requires you to have passed the Series 7 first. If you don't have the Series 7, you must take the Series 65 (standalone) plus the Series 63 separately.

QIs the Series 66 easier than taking Series 63 + Series 65?

The Series 66 is more efficient (one exam instead of two) and has fewer total questions (100 vs 190 combined). However, the passing score is slightly higher (73% vs 72%) and you must study for both topics at once.

QWhich is better for a career at a wirehouse?

For wirehouse advisors (Morgan Stanley, Merrill Lynch, etc.), you'll need the Series 7 anyway, so the Series 66 is the standard path. It gives you both agent and adviser registration in one exam.

QWhat if I only want to work at a fee-only RIA?

If you're certain you'll never sell securities (only give advice), the Series 65 is sufficient and doesn't require the Series 7. Many CFPs at fee-only RIAs only have the Series 65.
