According to Irrigation Association (IA) Certification Board, “The three-hour multiple-choice exam includes 125 questions covering:”[1]
The Irrigation Association (IA) Certification Board runs several credentials, including Certified Irrigation Contractor (CIC), Certified Irrigation Technician (CIT), CLIA and Certified Golf Irrigation Auditor (CGIA). Exams are delivered by computer at testing centers nationwide throughout the year.
Question counts and time limits differ by credential. CIT has 100 multiple-choice questions, while CLIA and CGIA each have 125. All three of those exams allow 3 hours. We have no verified question count for CIC, so check the candidate handbook for it.
The passing score is not announced in advance. According to the handbook, it typically ranges between 70% and 75%, depending on the exam.
IA recommends experience before you sit for an exam. For CIC, that is 3 years of irrigation-related field experience, or 2 years of field experience plus 1 year of education. For CIT, it is a minimum of 6 months or 1,000 hours of field experience. For CLIA, it is a minimum of 1 year of irrigation-related work experience.
Register at least 14 days before the exam date. If you do not pass, you must wait 90 days before a retake. The handbook allows a maximum of 3 attempts in 2 years, after which there is a 1-year wait.
Details can change, so confirm fees, current rules and your credential's specifics in the IA Certification Candidate Handbook.
The content areas below are copied from the official IA content outline published by Irrigation Association (IA) Certification Board. The right-hand column shows which of our practice sets covers it.
| Official content area | Practice on this site |
|---|---|
| Business management[5] | Mixed practice tests above Review the business and contracting topics in the official outline directly, since we have no dedicated practice set for this area. |
| Federal laws and codes[5] | IA Backflow Prevention & Cross-Connection ... Practise backflow prevention and cross-connection control, where codes decide which device or protection applies. |
| Irrigation design[5] | IA Irrigation Design & System Layout Work through system layout questions and explain to yourself why each design choice suits the site. |
| Irrigation installation[5] | IA Sprinkler & Emitter Technology Practise matching sprinkler and emitter types to the situation they are built for. |
| Irrigation scheduling[5] | IA Irrigation Scheduling & Evapotranspiration Practise how evapotranspiration, soil and plant needs translate into run times and schedules. |
| Maintenance and repair[5] | IA Electrical Components & Troubleshooting Practise diagnosing electrical and control faults by reasoning from the symptom back to the likely cause. |
| Water management and conservation[5] | IA Water Auditing & Irrigation Efficiency Practise audit and efficiency questions that ask how to measure, compare and reduce wasted water. |

These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.
Question: Schedule efficiency (SE) in irrigation describes:
Answer: B. How well the irrigation schedule matches actual plant water demand
Explanation:
The correct answer is that schedule efficiency describes how well the irrigation schedule matches actual plant water demand. The programmed run times are compared with the ET-based requirement, and over-scheduling wastes water and lowers the result.
The ratio of gallons applied to gallons metered is wrong because it compares two volumes of water and says nothing about what the plants needed. Pump motor efficiency is an equipment rating, unrelated to scheduling. The number of zones completed per hour measures speed, not whether the water applied was the right amount.
Rule to remember: schedule efficiency is about timing and amount against plant demand, not about hardware performance or how fast the system runs.
Question: What type of sensor can be wired to a controller's sensor input to automatically suspend irrigation when the soil has sufficient moisture?
Answer: B. Soil moisture sensor (tensiometer or capacitance probe)
Explanation:
A soil moisture sensor, such as a tensiometer or capacitance probe, is correct. It reports water content or soil water tension to the controller, which can then suspend a scheduled run when the soil is already adequately moist.
An anemometer measures wind, so it suits wind shutoff rather than soil conditions. A flow meter measures water moving through the pipe, which helps detect leaks or breaks but does not tell you how wet the soil is. A UV sensor measures light, not moisture in the root zone.
Rule to remember: pick the sensor by the condition it measures. Soil moisture is measured in the soil, and the controller's sensor input lets that reading override the schedule.
Question: Which controller program type allows different zones to run on different days of the week?
Answer: B. Day-of-week program
Explanation:
A day-of-week program is correct because it lets you assign specific days, such as Mon/Wed/Fri, to each zone. That flexibility helps when local watering restrictions limit which days are allowed.
An interval program runs on a repeating cycle of every N days, so zones follow the same rhythm rather than chosen weekdays. An odd/even day program follows the calendar date, which is a fixed pattern you do not tailor zone by zone. A single-run program is a one-time start, not a recurring weekly plan.
Rule to remember: if the question asks for named weekdays, think day-of-week. If it asks for a repeating gap between watering days, think interval. If it asks for calendar date parity, think odd/even.
Start with the official content areas and the candidate handbook for your credential, so you know which topics and rules apply to you. Then take a practice set for each area and treat the first attempt as a diagnostic rather than a score.
Because the passing score is not announced in advance, aim for steady understanding across every area rather than a target number. Remember the registration deadline and the retake waiting period when you pick a test date.
IA does not announce the passing score in advance. The candidate handbook says that, depending on the exam, it typically ranges between 70% and 75%. Check the handbook for your credential, and aim to understand every content area rather than target a single number.
CIT has 100 multiple-choice questions, and CLIA and CGIA each have 125. All three allow 3 hours. We have no verified question count for CIC, so confirm it in the IA Certification Candidate Handbook before you plan your test day.
You must register at least 14 days before the exam date. Exams are computer-based and delivered at testing centers nationwide throughout the year. Confirm current fees and scheduling steps with the Irrigation Association, since we do not list them here.
No candidate can retake an exam until 90 days have passed. The handbook also sets a maximum of 3 attempts in 2 years, after which there is a 1-year wait. Use the waiting time to review the areas where you were weakest.
IA recommends experience rather than listing a hard requirement here. For CIC, that is 3 years of field experience, or 2 years plus 1 year of education. For CIT, it is 6 months or 1,000 hours. For CLIA, it is 1 year of irrigation-related work experience.
No. We write the questions ourselves with AI tools, and they are not real exam questions. They are meant to help you practise the topics in the official outline and find gaps. Use the official IA material as your main source for what the exam covers.
