Series 65 (Investment Adviser Representative) Explained: Exam and Career Path

Not every US financial adviser sells products on commission. A large and growing share work on a fee basis instead, held to a fiduciary standard rather than a suitability standard — and the Series 65 is the licence that qualifies them to do it.

What is the Series 65?

The Series 65, formally the Uniform Investment Adviser Law Examination, is administered by FINRA on behalf of the North American Securities Administrators Association (NASAA). It qualifies a candidate as an Investment Adviser Representative (IAR) — someone who provides fee-based investment advice rather than earning commission on product sales, generally held to a fiduciary duty to act in the client's best interest.

Exam format

The exam consists of 130 scored questions plus 10 unscored questions, sat within a three-hour time limit, requiring at least 92 of the 130 scored questions correct to pass. The exam fee is $187. Unlike the Series 7, the Series 65 has no co-requisite requirement — candidates don't need to hold the SIE or any other exam first, which makes it a genuinely standalone qualification route.

No sponsorship required

Unlike the Series 7, which requires firm sponsorship before a candidate can even sit the exam, the Series 65 can generally be pursued more independently, which is part of why it's a popular route for people moving into financial planning or advisory work from an accounting, tax or other finance-adjacent background rather than a traditional brokerage career path. It's a similarly accessible entry point for career-changers as the SIE is for the brokerage side of the industry.

Series 65 vs Series 66

Candidates researching this space often find the Series 65 and Series 66 confusingly similar. The Series 66 combines the content of the Series 63 (state securities law) and Series 65 (investment adviser law) into a single exam, but it requires the Series 7 as a co-requisite — making it the right choice for someone who already holds or is pursuing a broker-dealer registration and wants investment adviser representative status alongside it. The standalone Series 65 is the more direct route for someone who only wants to work as a fee-based investment adviser representative, without a broker-dealer registration at all.

Series 65 vs Series 7: which career does it lead to?

The choice between these exams reflects a genuinely different business model, not just a different test. The Series 7 leads toward commission-based broker-dealer work with a broad product range and a suitability standard. The Series 65 leads toward fee-based advisory work — often financial planning, portfolio management or wealth advisory — under a fiduciary standard that generally requires putting the client's interests ahead of the adviser's own. Many independent registered investment adviser (RIA) firms are built entirely around Series 65-licensed advisers rather than commissioned brokers.

Career path

Series 65 holders typically work as investment adviser representatives at registered investment adviser firms, independent financial planning practices, or the advisory arms of larger wealth management firms. It's a common qualification for accountants and CPAs moving into holistic financial planning, since it complements existing tax and accounting expertise with the licensing needed to provide investment advice on a fee basis.

What the exam covers

The Series 65 syllabus centres on the regulatory and ethical obligations of investment advisers, economic and financial concepts relevant to portfolio and client advice, investment vehicle characteristics, and client and adviser relationship management — reflecting the exam's focus on advisory judgement and fiduciary responsibility rather than product-sales mechanics. This is a meaningfully different emphasis from the Series 7's heavier weighting toward specific product knowledge.

Alternatives that waive the Series 65

Certain existing professional credentials can waive some states' Series 65 requirement entirely — most notably the CFP, CFA and CPA designations in many US states, reflecting the overlap between what those credentials already test and what the Series 65 covers. Candidates who already hold one of these should check their specific state's requirements before assuming the Series 65 is mandatory, since waiver rules vary by state.

Frequently asked questions

Do I need the Series 7 before the Series 65?

No — the Series 65 has no co-requisite and can be pursued as a standalone qualification for candidates who only want to work as a fee-based investment adviser representative rather than a broker-dealer.

Is the Series 65 easier than the Series 7?

The two test different content rather than one simply being harder — the Series 65 has more scored questions (130 vs 125) and a higher raw pass threshold, but doesn't require the same breadth of product-specific knowledge the Series 7 covers.

Can accountants use the Series 65 to move into financial planning?

Yes — it's a common path for CPAs and accountants who want to add investment advisory services to an existing tax and accounting practice, since the fiduciary, fee-based model pairs naturally with client-facing accounting work.

If you're an accountant considering a move into fee-based financial advisory work in the US, pairing a core qualification such as ACCA or US CPA training with the Series 65 is a well-established route into that career.
