NASAA Series 66 passing score and results

The Series 66 passing score

NASAA requires at least 73 correct responses among the 100 scored Series 66 questions. The exam presents 110 multiple-choice items, but 10 are unscored pretest questions. The pretest items are not marked, so you cannot know which responses count while taking the test. Treat all items as scored and answer every question.

The 73 figure is a correct-answer count, not 73 out of all 110 presented items. Because there are 100 scored questions, 73 correct is also 73% of the scored count. Candidates do not need to estimate the pretest items or subtract them from a reported score. NASAA defines the pass threshold in terms of the 100 scored questions.

NASAA describes Series 66 as a criterion-based minimum-competency examination. The stated threshold is not an invitation to aim for exactly 73 in practice. A candidate cannot identify unscored items, and a preparation provider's set can differ from the official exam in content, difficulty, and construction. Treat practice results as diagnostics: they show which topics or reasoning skills need more work, not a guaranteed official score.

How the four areas relate to scoring

The 100 scored questions are weighted by content area: 8 questions on Economic Factors and Business Information, 17 on Investment Vehicle Characteristics, 30 on Client/Customer Investment Recommendations and Strategies, and 45 on Laws, Regulations, and Guidelines Including Prohibition on Unethical Business Practices.

Because the sections carry different weights, averaging four practice section percentages equally can mislead. Suppose a candidate gets 50% in economics, 80% in investment vehicles, 70% in recommendations, and 75% in law. The unweighted average is 68.75%, but that number is not the exam result because the sections contain different numbers of scored items. A weighted estimate based on the blueprint would be 4 + 13.6 + 21 + 33.75 = 72.35 correct-equivalent points out of 100, below 73. It is still only a rough estimate if the practice set does not mirror the official construction.

A similar pitfall occurs when a candidate focuses only on the 45% law section. Strong law knowledge helps, but weaknesses in client recommendations and product characteristics can still pull the total below the pass standard. Use section feedback to guide review and keep the smaller economics area in rotation.

A second example shows why a reported percentage from a practice vendor should be read with its denominator. Suppose a mock contains 40 law questions and you answer 30 correctly. That is 75% on that vendor's law set. The official Series 66 blueprint has 45 scored law items, but the vendor's questions may not represent the exact content balance or difficulty. You can say the result suggests some law knowledge; you cannot add 30 official points or infer a guaranteed pass.

When and how results are reported

Candidates receive the pass or fail result immediately after completing the exam. If you pass, the important next steps are to coordinate with the firm, confirm your Series 7 and SIE status where relevant, and complete the state registration process for the role. The pass does not let an unaffiliated person begin giving regulated advice or effecting securities transactions.

If you fail, NASAA provides scores within each of the four exam sections. This lets you see relative areas of strength and weakness. The report does not reveal which individual items you missed, provide an answer key, or disclose the text of exam questions. Use the section breakdown with your own study notes to identify specific topics for review.

Example: A candidate's section feedback shows stronger performance in economics and products but weaker results in recommendations and law. The next study cycle should emphasize client-profile analysis, registration distinctions, and ethics scenarios. Repeating economic formulas that the candidate already handles well may feel productive but is unlikely to address the main gap. A retake plan should turn the broad section signal into concrete topics and new practice cases.

Make a table from the report with one row per section and three columns: report result, subtopics you remember finding difficult, and next practice task. If recommendations is the weak section, the task might be a series of cases on time horizon, tax status, liquidity, account type, and portfolio concentration. If law is weak, split it into adviser and representative definitions, exemptions, filings, custody, communications, and prohibited practices. The report tells you where; your error log helps determine why.

A candidate should not calculate a passing score by averaging the four section percentages. For instance, a 90% in the 8-question economics area and a 70% in the 45-question law area do not receive equal weight. NASAA's FAQ notes that the exam is scored overall and the sections are weighted differently. Section scores help locate strengths and weaknesses; they are not four independent pass/fail decisions.

Retake timing for Series 66

NASAA's current schedule requires a 30-day wait after a first failure, a 30-day wait after a second failure, and a 180-day wait after a third unsuccessful attempt before the fourth and later attempts. Failures are counted for the same exam within a two-year period. A failure on Series 66 does not trigger the wait for Series 63 or Series 65, because the intervals apply to the specific exam.

For Series 66 enrollment windows opened on or after January 4, 2027, the interval after a third unsuccessful attempt changes from 180 days to 60 days. The first two waits remain 30 days. Windows opened before the effective date remain subject to the schedule that applied when they opened, so an existing window does not acquire the shorter interval merely because the calendar reaches January 4.

Suppose a candidate fails a third attempt under a window opened in late 2026. The 180-day wait remains tied to that window. If the candidate wants to use the reduced post-third-failure wait, NASAA says to open a new enrollment window on or after January 4, 2027. This is NASAA's own Series 66 policy, distinct from the waiting periods for FINRA qualification exams.

A retake requires a new enrollment and exam fee. Use the waiting period to study from section feedback, correct the actual misunderstandings, and work fresh questions. Memorizing recalled question phrasing is not a sound plan and can lead to a false sense of readiness.

Plan the retake date from the applicable rule and a readiness standard, not only from the earliest permitted day. If the weak section was law, use spaced retrieval and scenario practice across each law component. If the score report points to recommendations, practice integrating multiple client facts rather than memorizing product definitions. Schedule a full mock near the intended retake and use the result to decide whether the planned date is realistic.

What passing Series 66 means for registration

Series 66 is called the combined state-law exam because it can qualify an individual as if they had passed both Series 63 and Series 65. For IAR registration, the Series 7 must also be valid. NASAA's combined route also involves valid SIE and Series 7 qualifications for registration in both broker-dealer agent and IAR capacities. A candidate may take Series 66 and Series 7 in either order, but must complete both requirements before using the IAR route.

The exam itself may display as expired in CRD two years after its test date. NASAA explains that the underlying credits are reflected according to the capacities in which the person registers: an S63 exam credit for broker-dealer agent registration and an S65 credit for IAR registration. Those component credits follow their individual registration histories. The visible status of the combined exam should not be interpreted without looking at the relevant underlying credits and registration history.

After passing, the state still determines whether the application is complete and registration is granted. The firm typically files or maintains the required registration information, and a state may impose additional requirements such as an application, background check, bonding, or fees. Passing the exam satisfies an exam condition; it does not confer authority to transact business before approval.

The Series 66 result should be kept with the rest of the registration record. When an individual later registers in one or both capacities, the relevant Series 63 and Series 65 credits are reflected separately. If someone leaves the industry or moves between roles, the two credit histories may not match. A display showing the Series 66 exam itself as expired does not necessarily mean that every underlying credit is invalid; review the registration history and the credit required for the specific role.

A useful readiness check before your first attempt

Use a few types of evidence. First, take fresh timed practice covering all four domains, not only questions you have already seen. Second, check that your law knowledge includes distinctions such as agent versus adviser, state versus federal covered adviser, registration versus exemption, and disclosure versus conflict management. Third, solve product and client scenarios without relying on a chapter title that reveals the answer.

Review uncertainty as carefully as incorrect answers. If you guessed correctly on a question about an advisory fee conflict, write out the disclosure and client-interest issue. If you computed current yield correctly but confused it with coupon rate, practice explaining both formulas. If your mock results vary substantially, look at topic mix, question familiarity, and pacing before deciding that one score predicts the outcome.
