Every question is multiple-choice (A/B/C/D, one correct answer) and matches the style you will see on the real exam. The actual NASAA Series 66 question pool is confidential and assembled differently for each candidate, so these are CertFuel-authored to the same format, difficulty, and topic-weight distribution. The Series 66 exam itself: 100 scored questions, 150 minutes, 73% to pass, $177 fee, taken as a corequisite with the Series 7 (no SIE required).
The biggest area on the exam by far: the Investment Advisers Act and NASAA model rules, the adviser and IAR definitions, fiduciary duty, custody of client assets, compensation and soft dollars, and the long list of prohibited and unethical business practices. If you master one section, make it this one.
A financial planner charges clients an annual fee and, as part of that engagement, regularly advises them on which securities to buy and sell. Under the Uniform Securities Act, this person is most likely:
B is correct. The investment adviser definition turns on a three-part test, all of which are met here: the person gives advice about securities, does so as a business (regularly, not once), and receives compensation (the annual fee). Meeting all three brings a person within the definition.
A is wrong because giving advice for a fee is adviser activity, not the transaction-execution role of a broker-dealer. C is wrong because a planner who meets the three-part test is an adviser; the "solely incidental" exclusion does not apply once advice is a distinct, compensated service. D is wrong because an agent is an individual who represents a broker-dealer or issuer in effecting transactions, not someone paid a fee to advise.
The three-part adviser test (advice, business, compensation) is the gateway to the entire adviser framework, which dominates the Series 66. The exam repeatedly asks candidates to apply it to planners, insurance agents, and accountants whose facts sit near the exclusions.
An investment adviser directs a client's brokerage to a firm that charges higher commissions but gives the adviser free research and market-data terminals. What is the adviser's core obligation here?
B is correct. An adviser owes clients a fiduciary duty, which includes seeking best execution and disclosing conflicts. Paying higher commissions for research (a soft-dollar arrangement) can fall within a safe harbor only if the research is eligible and the adviser reasonably believes the commission is reasonable for the value received, and the arrangement must be disclosed.
A is wrong because the fiduciary duty constrains broker selection; the adviser is not simply free to ignore cost and conflicts. C is wrong because there is no automatic cash-rebate requirement; the duty is disclosure and reasonableness, not repayment. D is wrong because a research provider is not thereby transacting securities business as a broker-dealer.
The fiduciary standard separates advisers from the suitability world of broker-dealers, and soft dollars are a classic tested conflict. The safe harbor covers eligible research and brokerage services, not office rent, furniture, or travel, and everything must be disclosed.
An investment adviser wants to charge a fee based on a share of the capital gains in a client's account. This performance-based fee is generally permitted only when the client is:
B is correct. Performance-based fees tied to capital gains or appreciation are generally prohibited for retail clients and permitted only for qualified clients who meet a minimum assets-under-management or net-worth threshold. State-registered advisers must also satisfy the NASAA performance-based compensation exemption.
A is wrong because a signature does not make a retail client eligible; the thresholds do. C is wrong because age alone does not qualify a client for performance fees. D is wrong because a referral has nothing to do with performance-fee eligibility.
Compensation rules are a staple of the ethics section. Candidates must know that performance fees are the exception, not the rule, gated behind qualified-client status, while asset-based, hourly, and flat fees are broadly available.
An adviser is deemed to have custody of client assets. Which requirement applies?
B is correct. When an adviser has custody, client funds and securities must be held by a qualified custodian, and clients must receive account statements directly from that custodian at least quarterly. Advisers with custody are also generally subject to an annual surprise examination by an independent public accountant.
A is wrong because commingling client and firm assets is prohibited. C is wrong because no rule requires (or permits) a guarantee against loss. D is wrong because custody typically triggers more oversight, including the surprise exam, not less.
Custody is one of the most heavily tested ethics topics. The safeguards (qualified custodian, direct quarterly statements, surprise examination) all exist to keep client assets separated from the adviser and independently verified.
A broker-dealer agent proposes to split both the profits and the losses in a customer's account fifty-fifty. This arrangement is:
B is correct. Sharing in the profits or losses of a customer account is generally a prohibited practice. A narrow allowance exists only when the agent contributes proportionately and the customer gives written consent (with a further exception for immediate-family accounts). An even 50/50 split without a proportionate contribution does not qualify.
A is wrong because sharing in losses does not by itself make the arrangement permissible. C is wrong because accredited-investor status does not authorize profit-and-loss sharing. D is wrong because notifying the Administrator does not cure a prohibited sharing arrangement.
Profit-and-loss sharing sits alongside guaranteeing against loss and churning as core prohibited practices. The exam tests the narrow proportionate-contribution and family exceptions, which candidates often overlook.
Suitability and the client profile, tax considerations, retirement and special accounts, capital-market theory, and portfolio construction. Judgment-driven: many questions ask for the most suitable recommendation given a client's goals, time horizon, and ability to take risk.
A client says they are comfortable with aggressive risk, but they are 64, retiring next year, and will need the portfolio for living expenses. When willingness and ability to take risk conflict, the adviser should generally:
B is correct. Risk tolerance has two sides: willingness (subjective comfort) and ability (objective capacity given time horizon, income, and liquidity needs). When they conflict, the more conservative position generally prevails, and a client one year from retirement who needs the money has limited ability to take risk.
A is wrong because stated comfort cannot override a short time horizon and a near-term withdrawal need. C is wrong because a conflict between willingness and ability is a reason to recommend suitably, not to decline the client. D is wrong because a "market average" allocation ignores the client's specific profile, which is the heart of suitability.
Suitability is tested heavily in the recommendations section. The exam wants candidates to weigh time horizon and ability to take risk against a client's stated appetite, and to resolve conflicts conservatively.
A 45-year-old state-government employee wants a retirement plan they can tap before age 59 1/2 without the usual 10% early-withdrawal penalty. Which plan fits?
B is correct. A governmental 457(b) plan has no 10% early-withdrawal penalty on distributions before age 59 1/2 (distributions are still taxed as ordinary income). This is a key distinction from other salary-deferral plans.
A, C, and D are wrong because traditional IRAs, 403(b)s, and 401(k)s all generally impose the 10% penalty on distributions before age 59 1/2 (subject to specific exceptions).
Retirement-plan features are a recurring recommendations topic. The 457(b) "no early-withdrawal penalty" rule is a favorite exam distinction, along with the ability to defer into a 457(b) on top of a 401(k) or 403(b).
A client holds highly appreciated stock and asks how to minimize the capital-gains tax their heirs would owe. All else equal, holding the shares until death generally results in:
B is correct. Inherited assets generally receive a step-up in basis to their fair market value at the date of death, which erases the unrealized capital gain that built up during the owner's life. Gifting during life, by contrast, carries the donor's original basis to the recipient.
A is wrong because carryover basis applies to lifetime gifts, not inheritances. C is wrong because the step-up does not trigger an immediate capital-gains tax at death. D is wrong because the appreciation is not recharacterized as ordinary income to the heirs.
Tax-aware planning appears throughout the recommendations section. The step-up in basis at death versus carryover basis for lifetime gifts is one of the most tested planning contrasts on the exam.
To reduce a portfolio's overall volatility, an adviser wants to combine assets that do not move in lockstep. Which correlation between two assets provides the greatest diversification benefit?
B is correct. Correlation ranges from +1.0 (assets move together) to -1.0 (assets move in opposite directions). Combining assets with low or negative correlation reduces portfolio volatility the most, so a correlation near -1.0 gives the greatest diversification benefit.
A is wrong because a +1.0 correlation means the assets move identically, adding no diversification. C is wrong because +0.5 still leaves substantial shared movement; a more negative correlation diversifies better. D is wrong because correlation is central to how diversification lowers risk.
Portfolio-construction questions reward candidates who understand that diversification works through correlation, not merely by holding more positions. Pairing low- or negatively-correlated assets is how modern portfolio theory reduces total risk.
Features and risks of the investment vehicles: cash equivalents, fixed-income valuation and yields, equities, pooled products (mutual funds, ETFs, REITs), and derivatives. The Series 66 assumes Series 7 product knowledge and focuses on characteristics, valuation, and suitability rather than mechanics.
A bond trades at a premium (above par). Which ordering of its yields is correct?
What is a key difference between a futures contract and an option contract?
A is correct. In a futures contract, both the buyer and seller are obligated to complete the transaction. In an option, the buyer holds a right (not an obligation), and only the seller (writer) is obligated to perform if the buyer exercises.
B is wrong because standardized futures trade on exchanges; the private, customized contracts are forwards. C is wrong because futures are widely used to hedge (for example, locking in a commodity or interest-rate exposure). D is wrong because "loss limited to the premium" describes an option buyer, not a futures buyer.
The Series 66 tests derivatives at the definitions, uses, and risk level. The obligation-versus-right distinction between futures and options (and the futures-versus-forwards standardization point) is the kind of characteristic the exam expects candidates to know.
The smallest area (eight questions): analytical methods. Time value of money (present value, future value, internal rate of return), descriptive statistics (mean, median, standard deviation, Alpha, Beta, Sharpe ratio, correlation), and financial and valuation ratios.
An analyst wants to compare two portfolios on a risk-adjusted basis using total risk. The Sharpe ratio measures excess return per unit of:
B is correct. The Sharpe ratio equals (portfolio return minus the risk-free rate) divided by standard deviation, so it measures excess return per unit of total risk. A higher Sharpe ratio indicates better risk-adjusted performance.
A is wrong because beta captures only systematic (market) risk; the Sharpe ratio uses standard deviation, which reflects total risk. C and D are wrong because P/E and the current ratio are valuation and liquidity measures, not risk-adjusted return metrics.
The eight-question economic-factors section leans on descriptive statistics and analytical methods. Candidates should know that the Sharpe ratio uses standard deviation (total risk), which distinguishes it from beta-based measures.
Sample questions are most valuable when you treat each missed answer as a study prompt, not a score. Read the explanation, read the "why it matters" note, then revisit the underlying rule before moving on. The candidates who pass the Series 66 on the first try are the ones who can explain why each wrong answer is wrong, not just which letter is right.

Deciding between state law exams? The Series 66 combines agent and adviser law and is paired with the Series 7, while the Series 63 covers agent law only and the Series 65 covers adviser law as a standalone exam. Look up any unfamiliar term in the CertFuel glossary as you study.
How many questions are on the Series 66 exam?
The Series 66 has 100 scored questions plus 10 unscored pretest questions (110 total), and you have 150 minutes to complete it. You need to answer 73 of the 100 scored questions correctly to pass (73%). The 10 pretest questions are scattered throughout and are not identified.
What's the passing score for the Series 66?
The Series 66 passing score is 73% (73 of 100 scored questions). NASAA does not grade on a curve. There is no partial credit and no penalty for guessing, so you should always answer every question even if you are unsure.
Are these the real NASAA Series 66 exam questions?
No. The NASAA Series 66 question pool is confidential and copyrighted, and every candidate is assembled a different set of questions by a test algorithm. The sample questions on this page are CertFuel-authored to mirror the format, difficulty, and topic distribution of the real exam. Anyone selling "real" or "leaked" Series 66 questions is committing fraud, and using them puts your registration at risk.
What does the Series 66 actually test?
The Series 66 is the NASAA Uniform Combined State Law Exam, covering both state agent law and investment adviser law for candidates seeking dual broker-dealer agent and investment adviser representative registration. It is organized into four NASAA subject matters: Laws, Regulations, and Guidelines including the prohibition on unethical practices (the heaviest area at 45%, covering the Investment Advisers Act, NASAA model rules, fiduciary duty, custody, and prohibited practices), Client and Customer Investment Recommendations and Strategies (30%: suitability, tax, retirement, and portfolio construction), Investment Vehicle Characteristics (17%), and Economic Factors and Business Information (8%). See the Series 66 hub for the full topic weights.
How are Series 66 questions formatted?
Every Series 66 question is multiple choice with exactly four options labeled A, B, C, and D. Many are short scenarios: you read a brief fact pattern about an adviser, agent, or client, then pick the answer that reflects the correct rule or the most suitable recommendation. Others are straight definition, concept, or calculation questions. There are no essay or true-false questions.
Do I need the Series 7 for the Series 66?
The Series 66 has no SIE prerequisite, but it is normally a corequisite with the Series 7: states generally will not grant dual broker-dealer agent and investment adviser representative registration until you pass both the Series 66 and the Series 7. You can sit the two exams in either order. The NASAA Series 66 exam fee is $177. If you only need investment adviser representative registration and no broker-dealer role, the Series 65 alone is enough and does not require the Series 7.
How long should I study for the Series 66?
Most candidates who already have (or are pursuing) the Series 7 pass the Series 66 with about 4 to 6 weeks of consistent study. The Series 66 assumes the product knowledge from the Series 7 and concentrates on state and federal securities law, adviser regulation, and ethics. Working practice questions until you can explain why each wrong answer is wrong is the fastest path to a pass.
