What Is the Series 66 Exam?

Think of the Series 66 exam, officially known as the Uniform Combined State Law Examination, as the gateway to becoming a versatile financial professional. If you’re aiming to offer investment advice or facilitate securities transactions, this state-level licensing exam is your essential step.

It allows you to wear two hats: registered representative and investment adviser representative, unlocking a wide range of career possibilities in the financial industry.

Sponsored by the NASAA and administered by the FINRA, the Series 66 combines key elements from the Series 63 and Series 65 exams into one streamlined qualification. It’s like getting a two-for-one deal on credentials, covering everything from state regulations and fiduciary obligations to ethical practices.

This exam ensures that candidates not only understand the rules of the financial road but also know how to navigate the twists and turns of client relationships and compliance standards.

In short, the Series 66 is designed to give you the regulatory knowledge and ethical grounding you need to succeed as an investment adviser representative or securities agent, helping you stand out in a competitive market.

Exam Structure and Content

The Series 66 exam consists of 100 scored multiple-choice questions and includes ten unscored pretest questions used to evaluate future test content. It covers the following key areas:

  • Laws, Regulations, and Guidelines (30%): Understanding state and federal regulations governing investment advisers, broker-dealers, and securities agents, including prohibited practices.
  • Economic Factors and Business Information (10%): Analyzing economic trends, valuation factors, and tax considerations influencing investment decisions.

Prerequisite: Securities Industry Essentials (SIE) Exam

Before taking the Series 66 exam, candidates must successfully complete the Securities Industry Essentials (SIE) Exam, which serves as a co-requisite.
