- CID-AG is a two-exam pathway: General Agriculture plus either Sprinkler or Drip/Micro, so fees are charged per exam.
- Initial fees are $250 per exam for members and $495 per exam for nonmembers, totaling $500 or $990.
- Retakes cost $200 per exam for members and $325 for nonmembers, so a failed attempt is expensive.
- Annual renewal is $75 for members and $125 for nonmembers, plus $25 for each additional certification.
Why CID-AG Pricing Is a Two-Exam Calculation
Most people searching for the cost of the Certified Irrigation Designer - Agriculture credential expect a single number. That is not how this credential is structured. The Irrigation Association offers the Certified Irrigation Designer (CID) with an agriculture track, and earning it means passing two separate exams: General Agriculture and one specialty exam, either Sprinkler or Drip/Micro. Every fee in this article therefore applies per exam, and your real budget is the sum of both.
The General Agriculture exam is 150 multiple-choice questions with a four-hour allowance. The Sprinkler exam adds 50 questions (200 total across the pathway), and the Drip/Micro exam adds 75 questions (225 total). Each exam carries a four-hour allowance, which is why the eight-hour figure you may see in the handbook is an aggregate across two sittings rather than one marathon day. If you are still sorting out what the credential actually is, start with What Is CID-AG? before building a budget around it.
Initial Exam Fees: Member vs. Nonmember
The Irrigation Association prices initial exams at two tiers. Members pay $250 per exam. Nonmembers pay $495 per exam. Because you take two exams, the calculated totals are $500 for members and $990 for nonmembers.
| Fee Item | Member | Nonmember |
|---|---|---|
| Initial fee, per exam | $250 | $495 |
| Initial fees, two exams (General + one specialty) | $500 | $990 |
| Retake, per exam | $200 | $325 |
| Annual renewal | $75 | $125 |
| Additional certification, annual add-on | $25 | $25 |
The gap between member and nonmember pricing on exam fees alone is $490 across the two exams. Before assuming that membership automatically saves you money, compare that difference against the cost of joining, which is set by the Irrigation Association and is not part of the exam fee schedule. If you expect to renew annually for years, the member rate on renewal compounds the savings as well, since nonmembers pay $50 more every year.
How Your Specialty Choice Affects Cost
The published initial fee is the same whether you choose Sprinkler or Drip/Micro, so the specialty decision does not change the exam fee. It does change your preparation burden, and preparation time is the cost most candidates underestimate. The 20 domains you may see listed for this credential are really three separate outlines: entries 1-7 for General Agriculture, 8-16 for Drip/Micro, and 17-20 for Sprinkler. You take General plus one specialty, never all three outlines.
General Agriculture (Domains 1-7)
Required for everyone. The weighting rewards hydraulics and soils knowledge.
- Pumps (15%-20%)
- Hydraulics (20%-25%)
- Economics (5%-10%)
- Soil-Water-Plant Relations (15%-20%)
- Scheduling (10%-15%)
- Efficiency/Uniformity (10%-15%)
- System Components (10%-15%)
Drip/Micro Specialty (Domains 8-16)
Nine content areas, led by System Design/Economics at 20%-25%.
- System Design/Economics (20%-25%)
- Hydraulics (15%-20%)
- Filtration (15%-20%)
- Efficiency/Uniformity (10%-15%)
- Emitting Devices, Injection, Soil-Water-Plant Relations, Scheduling (each 5%-10%)
- Pumps (1%-5%)
Sprinkler Specialty (Domains 17-20)
Only four content areas, but one dominates the exam.
- Sprinkler Type (40%-50%)
- Hydraulics (20%-25%)
- Pumps and Power (15%-20%)
- Scheduling (10%-15%)
From a cost-of-failure standpoint, the Sprinkler exam is concentrated: nearly half the questions come from one domain, so a gap in sprinkler type knowledge is hard to offset elsewhere. Drip/Micro spreads risk across nine areas, but it is the longer exam at 75 questions. For a full breakdown of what each outline tests, see the complete guide to all 20 content areas. Choosing the specialty that matches your daily work usually reduces the chance of paying for a retake.
Retake Fees and the Cost of a Failed Attempt
Retakes are priced per exam, not per pathway. If you pass General Agriculture but miss the specialty, you retake only the specialty. The retake fee is $200 for members and $325 for nonmembers. That is cheaper than the initial fee, but not by much: a member retake costs 80% of the initial fee, so a single failure is a meaningful setback.
Two details make retake planning more complicated than a flat fee. First, the passing standard is form-dependent, generally falling between 70% and 75% rather than at one fixed universal cutoff, so you cannot assume a specific raw score is safe. Our breakdown of the CID-AG passing score covers how to think about that range. Second, both exams must be passed within three years of application. That window limits how long you can keep retaking, which is why it pays to treat each sitting as a serious attempt rather than a trial run.
If you are weighing your odds before you register, the article on how hard the CID-AG exam is and the data discussion in what the pass rate data shows will help you decide whether to invest more in preparation first. We do not publish an invented pass percentage here, because no verified figure is available in the sources behind this guide.
Annual Renewal and CEU Costs
Certification does not end the spending. Renewal is annual: $75 for members and $125 for nonmembers, with an extra $25 for each additional certification you hold. Over a decade of holding just this one credential, that is $750 as a member or $1,250 as a nonmember in renewal fees alone, before counting any continuing education.
The CEU Requirement
Maintaining the credential requires 20 CEUs every two years. Within those 20, at least 10 must be irrigation-related and at least 5 must be Tier 1, meaning water-efficiency focused. The remaining CEUs can be satisfied more flexibly. The cost here varies enormously by how you earn them: employer-sponsored training, conference sessions, and workshops all carry different price tags, and some are free if your employer covers them.
| CEU Requirement (per two years) | Minimum |
|---|---|
| Total CEUs | 20 |
| Irrigation-related CEUs | 10 |
| Tier 1 / water-efficient CEUs | 5 |
Because Tier 1 water-efficiency content is a distinct bucket, plan for it deliberately rather than hoping routine training will cover it. For the longer-term picture of whether recurring fees are justified, our ROI analysis of the CID-AG certification weighs these costs against career outcomes.
Costs Outside the Fee Schedule
The Irrigation Association fee schedule covers the exams and renewals, but several real expenses fall outside it. None of these are mandatory, and the amounts depend entirely on your choices, so treat the list below as a checklist rather than a price sheet.
- Association membership. The member rate saves $245 per exam on initial fees, but membership itself has its own dues, which are set separately.
- Study materials. No prep course is required, so this is optional. Candidates typically buy reference books, practice questions, or a structured course.
- An approved calculator. The exam is closed book with provided formula material and scratch paper. Only silent, battery-powered, nonprinting calculators are permitted; programmable models are allowed, but phone, tablet, and watch calculators are not.
- Travel to a testing site. Testing happens at Kryterion testing centers and during selected Irrigation Association paper-and-pencil administrations. At-home proctoring is not verified, so plan on travel.
- Time away from work. Each exam has a four-hour allowance, and breaks do not stop the clock. You are budgeting at least two half-day absences, not one.
Scheduling affects cost too. Which administrations are available, and when, determines whether you can sit both exams close together or must spread them out. Check the CID-AG exam dates and scheduling guide before you commit funds to a particular window.
Three Realistic Budget Scenarios
The scenarios below use only the fees confirmed in the Irrigation Association schedule. They exclude optional items such as study materials, travel, and membership dues, which vary by person.
| Scenario | Fees | Total |
|---|---|---|
| Member, passes both exams first try | 2 x $250 | $500 |
| Nonmember, passes both exams first try | 2 x $495 | $990 |
| Member, fails one exam once, then passes | $500 + $200 | $700 |
| Nonmember, fails one exam once, then passes | $990 + $325 | $1,315 |
Add first-year renewal ($75 member, $125 nonmember) and the full first-year outlay for a clean member pass reaches $575, versus $1,115 for a clean nonmember pass. The difference between the cheapest and costliest outcomes in the table is $815, which is large enough to justify spending effort on preparation up front.
Key Takeaway
The cheapest path is to pass both exams on the first attempt. Every retake adds $200 to $325, so effort spent before you register is almost always cheaper than effort spent after a failed sitting.
Where Prep Time Pays Off Most
Since fees are fixed, the controllable cost is how efficiently you prepare. The domain weights tell you where to spend hours. Hydraulics appears in all three outlines and is the heaviest single topic in General Agriculture (20%-25%) and Sprinkler (20%-25%), and it remains significant in Drip/Micro (15%-20%). Learning friction loss, pressure requirements, and pipe sizing well returns value on both exams you sit.
Hydraulics and Pumps
- Work hydraulics calculations by hand first, then with your approved calculator
- Cover General pumps (15%-20%) alongside Pumps and Power if you chose Sprinkler
Soil-Water-Plant Relations and Scheduling
- Cover soil-water-plant relations (15%-20% in General) and scheduling (10%-15%)
- Practice water-balance style problems
Your Specialty's Heavyweight Domain
- Sprinkler: dedicate extra time to Sprinkler Type (40%-50%)
- Drip/Micro: focus on System Design/Economics (20%-25%) and Filtration (15%-20%)
For a full preparation roadmap, see the CID-AG study guide, and keep the one-page cheat sheet handy for last-week review. You can also test yourself on realistic question styles with the CID-AG practice tests to find weak domains before you pay for a live attempt. Prior knowledge counts too: the handbook suggests three years in the field, or two years plus one related educational year, though experience and education are recommended rather than mandatory. See CID-AG requirements for eligibility details.
Finally, remember that the credential's value depends on the work it opens up. If you are deciding whether the expense makes sense for your situation, review earnings analysis and CID-AG jobs to see where the credential is put to use, and consider the structured practice question sets as a lower-cost way to build confidence before sitting for either exam.
Frequently Asked Questions
Because it requires two exams, the calculated initial fee total is $500 for Irrigation Association members and $990 for nonmembers, based on $250 or $495 per exam. This excludes retakes, renewal, study materials, travel, and membership dues.
Yes. The initial fee and retake fee both apply per exam. You pay for General Agriculture and for your chosen specialty (Sprinkler or Drip/Micro) as two separate fees.
Retakes are $200 per exam for members and $325 per exam for nonmembers. You only retake the exam you did not pass, and both exams must be passed within three years of application.
Annual renewal is $75 for members and $125 for nonmembers, with an additional $25 for each extra certification. You must also complete 20 CEUs every two years, including at least 10 irrigation-related and 5 Tier 1/water-efficient CEUs.
No prep course, degree, or reference count is required. Experience or education is recommended rather than mandatory, so study materials are an optional expense that you choose based on how prepared you already feel.
