CID-AG Exam Dates 2026: Testing Windows, Deadlines & Scheduling

Why "Exam Dates" Means Two Exams, Not One

Candidates searching for CID-AG exam dates often expect a single calendar entry: one test, one date, one registration. The Certified Irrigation Designer - Agriculture pathway, offered through the Irrigation Association (IA), does not work that way. It is a two-exam pathway, and each exam is scheduled and sat separately.

The structure looks like this:

That makes the General plus Sprinkler route 200 questions in total, and General plus Drip/Micro 225 questions. The source records describe an eight-hour exam allowance, but that figure is the aggregate across the two sittings, not a single eight-hour session. Nobody sits for eight hours straight.

Because every question is multiple choice and the two exams are separate events, "when is the exam?" really becomes two scheduling decisions. If you want a broader picture of what each exam covers before you commit to dates, the CID-AG exam domains guide walks through all 20 content areas.

Testing Windows: Kryterion Centers and IA Paper Administrations

The verified delivery options are limited to two channels:

• Kryterion testing centers - the standard computer-based route, where you schedule a seat at a proctored center.
• Selected IA paper-and-pencil administrations - offered at specific Irrigation Association events or sessions rather than on demand.

Whether at-home online proctoring is available for this credential has not been verified, so do not plan around it. If you see a third-party site advertising remote testing for the CID agriculture track, confirm it directly with the IA before paying anything.

In practical terms, the computer-based route gives you flexibility to pick a date when a center has openings, while the paper route ties you to wherever and whenever IA runs a session. Many candidates who want to compress their timeline favor the Kryterion route; candidates who attend IA events anyway sometimes prefer to sit the paper exam there.

The Three-Year Clock That Drives Your Real Deadline

The single most important date rule in the pathway is this: both exams must be passed within three years of your application. This is a rolling personal deadline, not a fixed calendar date, and it is the real "deadline" most candidates need to manage.

What this means in practice:

• Your application date starts the clock.
• You can pass the General Agriculture exam first and the specialty exam later, but both must land inside the three-year window.
• Failed attempts consume time as well as money. Retakes cost $200 per exam for members and $325 for nonmembers, and each retake must still fit inside the window.

For most working designers, three years is generous. The risk is not the length of the window but procrastination: candidates pass General Agriculture, feel relieved, and let the specialty exam drift. A sensible approach is to schedule the second exam before you leave the testing center after the first.

Choosing Sprinkler or Drip/Micro Before You Book

You must choose your specialty exam, and that choice affects both your schedule and your workload. The two options differ sharply in size and emphasis.

A note on the domain numbering: the 20 listed domains are actually 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 as a single exam. Use your own field experience to choose: if your daily work is center pivots and solid-set systems, Sprinkler is the natural fit; if you design for orchards, vineyards, or row crops under drip, choose Drip/Micro. The difficulty guide discusses how the two tracks compare in feel.

Registration Mechanics and Fees

Because each exam is registered and paid for separately, understanding the fee structure helps you decide how to space your attempts.

The nonmember premium on the two-exam total is large enough that candidates should compare it against the cost of IA membership before registering. The full breakdown, including renewal and CEU costs, is in the CID-AG certification cost guide.

Experience Guidance (Recommended, Not Mandatory)

The handbook suggests three years in the field, or two years plus one related educational year. This is a recommendation rather than a gate: no mandatory prep course, degree, or reference count has been identified. That means you can generally apply when you are ready, but the guidance is a useful signal for how much practical background the questions assume. Details on eligibility are covered in the requirements article.

Handbook Version Caution

The currently linked handbook has no verified revision year. A 2010 Drip/Micro sample exists, but that is a sample, not the blueprint date. Before you build your study schedule around specific percentages, download the latest handbook from the IA and confirm the outlines match what you have been studying.

What Happens on Test Day

Knowing the rules in advance affects how you schedule, because the format shapes how tiring each sitting will be.

• Closed book. You work from provided formula material and scratch paper.
• Calculators: silent, battery-powered, nonprinting calculators are permitted, and programmable models are allowed. Phone, tablet, and watch calculators are not.
• Breaks do not stop the clock. Time you spend away from the screen or paper still counts against your four hours.
• Passing standard: form-dependent, usually 70%-75%, rather than one fixed universal cutoff.

The General Agriculture exam's 150 questions in four hours works out to under two minutes per question on average. The Sprinkler exam's 50 questions in the same four hours allows far more time per item, which tells you those questions are likely more involved. Drip/Micro, at 75 questions, sits in between. Plan your pacing practice accordingly.

Sequencing the Two Sittings Around the Domains

This is the one place where a study timeline earns its keep, because the order in which you sit the exams should follow the content overlap. Most candidates take General Agriculture first, since its foundations (pumps, hydraulics, soil-water-plant relations, scheduling) underpin both specialties.

For the full preparation method and resource recommendations, the CID-AG study guide goes deeper, and the cheat sheet is useful for last-week review. When you want timed practice that mirrors the multiple-choice format, the CID-AG practice tests let you rehearse pacing before committing to a testing date.

Why Not Back-to-Back on One Day?

The source records frame the eight-hour allowance as aggregate across two sittings, and each exam is four hours with breaks not stopping the clock. Even if scheduling the two close together were possible, doing both would be exhausting. Separating them by a few weeks lets you reset and shift your focus from general principles to specialty detail.

After You Pass: Renewal Dates and CEU Deadlines

Certification is not a one-time event, so your calendar does not end at the testing center. Renewal runs on an annual fee cycle of $75 for members or $125 for nonmembers, with an additional $25 if you hold an additional certification. On top of fees, you need 20 CEUs per two years, including a minimum of 10 irrigation-related CEUs and 5 Tier 1 (water-efficient) CEUs.

Build these into your calendar from the start: track CEUs as you earn them rather than scrambling near the end of the two-year period. If you are weighing whether the ongoing commitment pays off, the ROI analysis and salary guide address earning potential, and the CID-AG jobs page covers the kinds of employers and roles where the credential carries weight.
