- The SSP exam covers four agronomy domains: nutrient, soil and water, pest, and crop management, each viewed through a sustainability lens.
- People and Society, Planet and Environment, and Profits and Economics are competency lenses, not additional exam domains.
- You must already hold an active CCA credential in good standing, and the exam fee is USD $170.
- The current performance objectives are the second generation, effective October 2022, and they define what each domain can test.
How the Four Domains and Three Lenses Fit Together
The Certified Crop Adviser - Sustainability Specialty, which the American Society of Agronomy styles as SSp, is an add-on to the International Certified Crop Adviser program. It was developed with the United Soybean Board and centers on United States agricultural sustainability. If you want the broader picture first, start with What Is SSP Certification? and then return here for the content breakdown.
The exam organizes its content into four official agronomy domains:
- Sustainability and Nutrient Management
- Sustainability and Soil and Water Management
- Sustainability and Pest Management
- Sustainability and Crop Management
Layered over all four are three competency lenses: People and Society, Planet and Environment, and Profits and Economics. This is the single most common point of confusion for new candidates. The lenses are not replacements for the four domains and are not separate exam sections. They describe how you are expected to reason inside every domain. A question about split nitrogen applications, for example, is a Domain 1 question, but a strong answer weighs nutrient loss to water (Planet and Environment), input cost and yield response (Profits and Economics), and community or neighbor impacts (People and Society).
The official performance objectives are the authority on what is in scope. The current linked set is the second generation, effective October 2022. Print them, and treat every objective as a potential question stem. For a one-page companion to this guide, see the SSP cheat sheet.
Domain 1: Sustainability and Nutrient Management
Nutrient management is where the sustainability framing is most tangible, because nutrient losses link directly to water quality, input cost and public perception. The exam wants you to move beyond "apply the recommended rate" to explaining why a practice reduces loss and what trade-offs it carries.
Domain 1 Focus Areas
Think in terms of the nutrient source, rate, timing and placement decision, and how each choice shifts losses to air and water.
- Nutrient loss pathways: leaching, runoff, erosion-bound phosphorus, volatilization and denitrification
- Source, rate, timing and placement trade-offs, including split applications and in-season adjustment
- Use of soil, tissue and field-scale information to justify rates rather than defaulting to habit
- Manure and other organic nutrient sources as both a resource and a risk
- Economic framing: when a lower-loss practice also protects margin, and when it costs more
- Communicating nutrient stewardship to farmers, neighbors and downstream stakeholders
Scenario patterns to practice
Expect scenario-style prompts in which a grower faces a field with a vulnerable feature, such as tile drainage, coarse soils, or proximity to a stream, and you must choose the most defensible nutrient plan. The best answer usually reduces loss risk and remains economically workable. Practice explaining why an answer is better, not just which one is correct, because distractors are often agronomically plausible but ignore one of the three lenses.
Domain 2: Sustainability and Soil and Water Management
This domain ties soil function to water outcomes. Soil is treated as both a production asset and an environmental buffer, so questions often ask how a practice changes erosion, infiltration, organic matter, water quality or water use.
Domain 2 Focus Areas
Connect what happens in the soil profile to what leaves the field.
- Soil health concepts: structure, aggregation, organic matter, biological activity and compaction
- Erosion and sediment control, including tillage systems, residue cover and cover crops
- Water quality protection: buffers, drainage management, and practices that intercept runoff and leachate
- Water use and irrigation efficiency where applicable, including scheduling decisions
- Monitoring and indicators that show whether a practice is working
- Cost, labor and equipment realities that shape whether growers adopt a practice
Why this domain rewards systems thinking
A single practice rarely solves a soil or water problem alone. Reduced tillage may protect soil structure but change nutrient stratification or pest pressure; cover crops may improve infiltration but add management complexity and cost. Candidates who can articulate these cross-domain effects tend to handle the harder scenario questions more comfortably.

Domain 3: Sustainability and Pest Management
Pest management in this specialty is framed around integrated approaches that reduce risk while protecting yield and profit. The sustainability angle emphasizes durable tools, resistance management, non-target effects and the human and environmental consequences of pest control choices.
Domain 3 Focus Areas
Favor decision-making that keeps tools effective and impacts low over time.
- Integrated pest management: scouting, thresholds, cultural, biological and chemical options
- Resistance management and the long-term value of diversified control tactics
- Pesticide stewardship, including drift, runoff, pollinator and non-target considerations
- Crop rotation, residue and cultural practices as pest-suppression tools
- Economics of control: cost of action versus cost of inaction
- Applicator, neighbor and community considerations under People and Society
Domain 4: Sustainability and Crop Management
Crop management is the integrating domain. It covers cropping system design and the farm-level choices that determine how nutrients, soil, water and pests interact across seasons. Because it is the most system-oriented, it often pulls in concepts from the other three.
Domain 4 Focus Areas
Evaluate whole-system choices, not isolated practices.
- Crop rotation, diversification and sequencing, including the role of legumes and cover crops
- Variety or hybrid selection, planting date and population as sustainability and risk levers
- Precision agriculture technologies and when their cost is justified by outcomes
- Whole-farm economics: margins, risk, adoption barriers and incentive or cost-share programs
- Harvest, residue and field operation decisions that affect soil and downstream resources
- Societal expectations, supply-chain sustainability requests and how to advise growers on them
Where economics shows up
The Profits and Economics lens is most visible here. A practice that improves the environment but cannot be sustained financially is not a complete recommendation, and the exam rewards answers that recognize this. At the same time, it rewards awareness that short-term cost cutting can create long-term soil, water or market risk.
What the Questions Feel Like
The SSP is a computer-based, multiple-choice specialty examination. Under standard conditions it is closed book with an on-screen calculator, one blank sheet of scratch paper and no breaks. In practice, that means you should build fluency with the reasoning rather than counting on lookup.
| Question tendency | What it tests | How to prepare |
|---|---|---|
| Field scenario with a constraint | Choosing the most defensible practice for a specific situation | Practice naming the constraint first, then eliminating options that ignore it |
| Trade-off between two good options | Weighing lens-based consequences across people, planet and profit | For every practice you study, write one benefit, one cost and one risk |
| Cross-domain integration | Seeing how a nutrient, soil, pest or crop choice affects the others | Map each practice to the domains it touches |
| Calculation or applied reasoning | Basic quantitative judgment using the on-screen calculator | Rehearse rate, cost and loss-reduction arithmetic by hand |
Passing is set through the program's Modified Angoff standard-setting process, so what counts as a passing performance is determined by expert judgment about minimally competent candidates rather than a simple curve. For the specifics, see SSP Passing Score and SSP Pass Rate, and try realistic scenario items on the SSP Exam Prep practice test site.
Sequencing the Domains in Your Prep
You do not need a generic study system; you need a sensible order. Because Domain 4 pulls from the others, it works best near the end. Start with the domain that anchors the most vocabulary, then build toward integration.
Orient and Nutrients

- Scheduling: You must register and sit within the published specialty examination windows. See SSP Exam Dates.
After You Pass: CEUs and Career Context
Holding the specialty requires maintaining the underlying CCA certification and paying annual certification fees. Under the March 2026 ICCA policy manual, you need 40 total CEUs per two-year cycle, including 5 Sustainability Specialty CEUs. The overall CCA requirements also include at least 5 CEUs in each of the four standard agronomy categories, 1 ethics CEU and at least 20 board-approved CEUs.
Key Takeaway
The 5 Sustainability Specialty CEUs count within the 40 total. They do not create a 45-CEU requirement, so plan your continuing education so sustainability-focused sessions also help satisfy your broader CCA categories where eligible.
The specialty is aimed at practicing crop advisers who counsel growers on field-level decisions, so it tends to be most relevant to agronomists, retail and cooperative advisers, consultants and others who work with farm operations.
