Are 403(b) Advisers Fiduciaries? A Teacher’s Guide to Financial Advice

A teacher deciding whether to sign a 403(b) enrollment form is rarely told which legal standard the person recommending it works under. That standard is not a matter of personality or good intentions. It is set by federal securities law, by the rules of the Financial Industry Regulatory Authority, or by state insurance law, and it differs depending on which of those regimes the professional is registered under and which capacity they are acting in at that moment.

This article is aimed at Kansas and Missouri educators at any career stage who have encountered financial products in the staff room and want to know, factually, what a fiduciary is, what the other standards are, and what questions to ask anyone offering help. It describes the standards as the regulators state them; it does not rank channels, and it does not present any firm's registration status as a measure of quality - the SEC requires every adviser's Form ADV Part 2A brochure to state that registration "does not imply a certain level of skill or training." The related reading covers the 403(b) vendor questions and the retirement mistakes these conversations tend to produce.

What the fiduciary standard is

An investment adviser registered under the Investment Advisers Act of 1940 owes its clients a fiduciary duty. In its 2019Commission Interpretation Regarding Standard of Conduct for Investment Advisers(Release No. IA-5248), the U.S. Securities and Exchange Commission (SEC) stated that this duty "comprises a duty of care and a duty of loyalty" and" applies to the entire adviser-client relationship" - not only to individual recommendations. Its judicial root is SEC v. Capital Gains Research Bureau (1963).

The duty of care, per the interpretation, includes "the duty to provide advice that is in the best interest of the client," the duty to seek best execution of transactions where the adviser selects the broker, and "the duty to provide advice and monitoring over the course of the relationship." The duty of loyalty "requires that an adviser not subordinate its clients' interests to its own": an adviser" must eliminate or at least expose through full and fair disclosure all conflicts of interest," and a client's informed consent to a disclosed conflict may be explicit or, depending on the facts, implicit.

Two points keep the standard in proportion. The SEC's interpretation states that "the fiduciary duty follows the contours of the relationship between the adviser and its client" - the scope of services agreed in writing shapes what the duty covers. And a fiduciary duty is a standard of conduct, not an assurance of results: it governs how advice must be given, not what the markets or the tax code will do afterwards.

Three standards, three regulators

Financial professionals an educator is likely to meet fall under one of three regimes. Investment advisers (SEC- or state-registered) owe the Advisers Act fiduciary duty described above. Broker-dealers and their registered representatives are subject to Regulation Best Interest when they recommend a securities transaction or strategy to are tail customer. Insurance producers selling annuities are regulated understate insurance law, including the National Association of Insurance Commissioners' annuity model regulation where a state has adopted it.

Regulation Best Interest (Reg BI) was adopted by the SEC on June 5, 2019, with compliance required from June 30,2020. Under it, "when making a recommendation of a securities transaction or an investment strategy involving securities, a broker-dealer must act in the retail customer's best interest and cannot place its own interests ahead of the customer's interests." It comprises four obligations - disclosure, care("reasonable diligence, care and skill when making a recommendation"),conflict of interest, and compliance - and it attaches at the point of recommendation. The same 2019 rulemaking adopted Form CRS and the adviser fiduciary interpretation together.

For annuities, the NAIC's 2020 revision of its Suitability in Annuity Transactions Model Regulation (Model #275) requires that "all recommendations by agents and insurers must be in the best interest of the consumer and that agents and carriers may not place their financial interest ahead of the consumers' interest in making are commendation." The NAIC reported, as of February 2025, that 48 states had adopted the revisions; whether and how a particular state has done so is a state-by-state question this article does not answer for Kansas or Missouri, and state insurance regulators have overseen annuity suitability since 2003.

Why the 403(b) marketplace makes the question concrete for educators

The K-12 403(b) marketplace puts the standard-of-conduct question in front of teachers more often than most workers face it. Many districts offer a multi-vendor line-up rather than a single plan, some products are distributed on a commission basis, and some annuity-based contracts carry surrender schedules that apply if money is moved within a set period. None of that is improper; each is a structural feature that determines which regime the person at the table is working under.

The practical consequence is that two educators in the same building can sign 403(b) paperwork with two professionals operating under different standards - one recommending under Reg BI, one advising as a fiduciary, one selling an annuity under state insurance law - without either teacher knowing which. The companion article on retirement planning for first-year teachers sets out the vendor questions to ask about contract type, fees, and surrender schedules; this article adds the one that comes before them: which standard applies to the person recommending it, and where does it say so?

How to check any adviser or firm

Every professional an educator meets can be checked against public records. Investor. gov's free "Check Out Your Investment Professional" tool "uses the SEC's IAPD (Investment Adviser Public Disclosure) database as a one-stop shop" at adviserinfo.sec.gov, showing registration history, current and past firms, and "a summary of certain disciplinary events." FINRA's Broker Check is "a free tool from FINRA that can help you research the professional backgrounds of investment professionals, brokerage firms and investment adviser firms."

Two documents complete the picture, and both are yours to request. Form ADV Part 2A - the brochure - must be delivered to advisory clients "in plain English" and is "made available to the public on the IAPD website"; it covers the adviser's services, fees and compensation, methods of analysis, disciplinary information, code of ethics, and brokerage practices, with an annual summary of material changes. Form CRS, the relationship summary that broker-dealers and investment advisers must provide to retail investors, states whether the firm offers brokerage services, advisory services, or both; its fees ("commissions, ongoing asset-based fees, fixed fees, wrap fee program fees"); its conflicts; the applicable standard of conduct; and any reportable disciplinary history. Copies are available at Investor.gov/CRS. Information about an adviser's individual representatives is available from the firm on request. For insurance producers, the state insurance regulator is the licensing authority.

Investor.gov puts the first question plainly: "The most important question that you should consider before hiring an investment professional is whether the person is registered with us or with a state securities regulator." The author's firm is an SEC-registered investment adviser; what that registration does and does not mean is set out, in the SEC's own required language, in the Important information section at the end of this article.

The questions to ask anyone offering financial help

Three questions, asked before any form is signed, establish the terms of the relationship. First, in what capacity are you acting with me - investment adviser, broker-dealer representative, insurance producer, or more than one - and which standard of conduct applies? Second, how are you paid for this recommendation - commissions, an asset-based fee, a fixed fee, a wrap fee - and by whom? Third, what conflicts of interest do you have, and where are they disclosed in writing?

Form CRS is designed to answer all three and includes conversation-starter questions for that purpose; asking for it, and for the Form ADV Part 2A where the firm is an investment adviser, is an ordinary request that any registered firm expects. A professional's answers should match the documents. Where they do not, the documents govern.
