1.5 Topic Weights and Session Map
Key Takeaways
- Official 2026 weights: Ethics 15–20%; FSA, Equity, and Fixed Income 11–14% each; Portfolio Management 8–12%; Alternatives 7–10%; Quant, Economics, and Corporate Issuers 6–9% each; Derivatives 5–8%.
- The 180 items are split across two sessions, but CFA Institute does not guarantee a fixed topic-to-session mapping — expect a mix in each session.
- Ethics, FSA, Equity, and Fixed Income together can account for roughly half the exam, so they justify proportionally more study time.
- Weights guide time allocation; they do not license abandoning any topic when the pass margin is narrow.
Weight ranges as an allocation tool
Topic weights tell you where the exam concentrates its questions, but they do not grant permission to ignore anything. With a 45% pass rate and a narrow MPS, a 6% topic can decide a borderline result. The correct use of weights is proportionate time, not selective blindness.
Here are the official 2026 Level I topic weights. CFA Institute publishes them as ranges because the exact item count per topic can vary by form:
| Topic area | 2026 weight | Approx. items (of 180) | Study implication |
|---|---|---|---|
| Ethical and Professional Standards | 15–20% | ~27–36 | Start early; drill scenario cases repeatedly |
| Quantitative Methods | 6–9% | ~11–16 | Build calculator speed and interpretation |
| Economics | 6–9% | ~11–16 | Link policy, cycles, trade, and FX |
| Financial Statement Analysis | 11–14% | ~20–25 | Practice statements, ratios, quality signals |
| Corporate Issuers | 6–9% | ~11–16 | Governance, WACC, capital structure, models |
| Equity Investments | 11–14% | ~20–25 | Markets, indexes, industry work, valuation |
| Fixed Income | 11–14% | ~20–25 | Yields, pricing, duration, convexity, credit |
| Derivatives | 5–8% | ~9–14 | Payoff logic and no-arbitrage intuition |
| Alternative Investments | 7–10% | ~13–18 | Structures, fees, liquidity, diversification |
| Portfolio Management | 8–12% | ~14–22 | Risk, return, MPT, CAPM, the IPS |
Notice that Ethics, FSA, Equity, and Fixed Income together can reach roughly 48–62% of the exam. They earn the most first-pass and review hours.
Session map — what is and is not guaranteed
The 180 items are split into two 135-minute sessions, but CFA Institute does not publish a fixed topic-to-session assignment. You should expect a mix of topics in each session and not assume, for example, that all Ethics questions fall in Session 1. Plan to switch between ethics judgment, calculations, macro reasoning, accounting detail, and asset-class analysis within a single session. Practicing mixed-topic sessions builds the mental gear-shifting the real exam demands; do not over-index on a rumored fixed order.
Converting weights into hours
Start from your total budget. On a 300-hour plan, a 15% topic implies roughly 45 hours, an 11% topic about 33 hours, and a 6% topic about 18 hours, before final-review adjustments. Then override the baseline for personal weakness: an accountant may need less first-pass FSA time and more Fixed Income; a non-statistics background may need extra Quant. Weights set the default; diagnostic practice tells you where to deviate.
Ethics and the close-score problem
Ethics is the single heaviest range and threads through professional conduct everywhere. It is also where two answers often both look professionally reasonable, so memorizing slogans fails. Practice the conduct implication, not just the rule: what changes when a client requests an unsuitable trade, when a supervisor pressures a research conclusion, or when a candidate discusses exam content online (a direct Standard VII violation). CFA Institute has historically applied an 'ethics adjustment' — borderline candidates near the MPS can be helped or hurt by their ethics score — which is another reason not to defer it to the final week.
Minimum competence floor
Set a floor for every topic: know the core definitions, key formulas, decision rules, and the two or three classic traps. Only after clearing that floor should you pour extra hours where high weight and personal weakness overlap. This builds a resilient score profile, far safer than perfecting one topic while leaving another blank.
Reading the topic-band feedback after the exam
CFA Institute does not release a raw score; instead, results show your performance in each topic against the MPS, typically displayed in bands or as above/at/below the maximum-points line per topic. Understanding this in advance shapes strategy. Because the report is per topic, a profile of consistent mid-range performance across all ten areas is generally safer than spiking in three topics and bottoming out in two — the latter can sink you even with a strong overall feel.
This is the analytical case for the competence floor: lifting your two weakest topics from 'below' to 'at' the line often moves the result more than pushing an already-strong topic from good to excellent.
A weight-to-priority worked example
Suppose a diagnostic mock shows you scoring 80% in Equity (weight 11–14%) and 45% in Fixed Income (weight 11–14%). Both carry equal weight, so the expected-points gain from study is larger in Fixed Income simply because you have more room to improve there. Now compare Fixed Income (11–14%) against Derivatives (5–8%), where you also score 45%: the same percentage-point improvement in Fixed Income yields more raw exam points because the topic is bigger.
The rule that falls out is: prioritize topics where (room to improve) × (topic weight) is largest. Ethics, FSA, Equity, and Fixed Income usually dominate that product, which is why they anchor most study calendars.
The ethics-adjustment nuance
Historically, CFA Institute has applied an ethics adjustment: for candidates whose total score sits near the MPS, a strong ethics performance can tip them over and a weak one can tip them under. The exact mechanics are not published, but the takeaway is firm — Ethics is not just the heaviest topic by weight, it can carry extra leverage at the margin. Treat it as a year-long thread of repeated scenario practice, not a final-week cram, and you protect both its direct 15–20% and its potential tie-breaking effect.
