1.1 The CIT Credential & Exam Structure

The CIT Credential & Exam Structure

Quick Answer: The Irrigation Association (IA) Certified Irrigation Technician (CIT) exam tests field installation, maintenance, and electrical/hydraulic troubleshooting skills. It is 100 equally weighted multiple-choice questions with a 3-hour (180-minute) time limit, offered in English and Spanish. The IA does not announce the passing score before an administration; the Certification Candidate Handbook states it typically ranges between 68% and 72%.

The Certified Irrigation Technician (CIT) is the Irrigation Association's entry-level field-technician credential. The IA defines a CIT as "an entry-level irrigation field professional who is installing, repairing and/or maintaining irrigation systems" — a person in the field, not the business owner. (The contractor-level credential is the CIC; the design credential is the CID.) The CIT validates that a technician can install piping, water-delivery components, irrigation controls, and backflow prevention devices; cut and join pipe; apply basic irrigation principles and hydraulics; and troubleshoot and repair system components.

Candidate Prerequisites & Field Experience

The IA sets recommendations, not hard prerequisites, for the CIT:

• Experience Recommendation: A minimum of six months or 1,000 hours of irrigation-related field experience before taking the exam.
• No Education Requirement: There is no degree or formal training prerequisite.
• Program Window: Candidates have one year from the date of application to complete the program.
• Ethical Commitment: Every candidate must accept the Select Certified Code of Ethics; acceptance is required for application approval.
• Practical Skills Assumed: Solvent-welding PVC, setting rotors and sprays, wiring 24 VAC solenoid valves, operating a digital multimeter, reading irrigation plans, and taking static and dynamic pressure readings.

Exam Mechanics & Format

* Programmable calculators are permitted provided they are silent, battery-operated, and non-printing. Smartphones, tablets, smart watches, pagers, and PDAs are not approved for use on any IA exam.

Why There Is No Published Cut Score

Individual forms of the CIT exam contain different blends of questions to protect exam security. The IA statistically equates forms by analyzing the relative difficulty of every item, which produces a pass-fail score specific to the form the candidate sat. That is why the passing score is not announced in advance. Treat any figure you see quoted as "the CIT passing score" — including the widely repeated "75%" — as unofficial. Plan for 68%-72% as the published typical range and build a margin above it.

Exam-Day Reference Materials: What Is and Is Not Provided

The handbook's general exam-day policy states that scratch sheets and equation sheets will be provided. However, the CIT specification sheet itself lists only a calculator and #2 pencils as supplemental materials, and — unlike the CID, CAIS, CLIA, CGIA, and CIC specifications — it does not list an equation sheet among its references. The IA's landscape exam-resources page likewise publishes no downloadable CIT equation sheet.

Plan accordingly: memorize the core constants. The following appear throughout CIT hydraulics and electrical items:

$\text{Precipitation Rate (PR)} = \frac{96.3 \times \text{GPM}}{\text{Area (sq ft)}}$ $\text{Ohm's Law: } V = I \times R \quad (\text{Volts} = \text{Amps} \times \text{Ohms})$ $1\text{ psi} = 2.31\text{ feet of head} \qquad 1\text{ foot of head} = 0.433\text{ psi}$

Official Exam Domain Breakdown

The CIT detailed content outline in the Certification Candidate Handbook lists three domains. Memorize the domain names as the IA writes them — items are drawn from these headings, and the weights tell you where to spend study time.

1. Understanding Basic Irrigation Principles (41% - 46%)

The largest domain, and the one most often under-studied. Its thirteen lettered topics are: sprinkler type / nozzle type and spacing; swing joint assemblies; pipe fittings and connection procedures; equipment and tool usage; pumps; backflow functionality; plans and as-built documentation; water meter usage; job safety; startup and winterization procedures; identifying leaks; identifying all water supplies; and basic soil-plant-water relationships.

2. Understanding Electrical Principles (28% - 32%)

Six lettered topics: voltmeter operation (voltage, resistance, continuity, amperage/watts); controller electrical operation (programming, diagnostics, reset procedures, component replacement); transformer operation (testing incoming/outgoing voltage, matching a replacement); solenoid operation (resistance and incoming voltage testing); wiring types (wire size, type, burial depth); and field wiring, wire tracking, and valve locating (equipment selection, setup, splicing).

3. Understanding Hydraulic Principles (26% - 27%)

Six lettered topics: sensors; valves; pressure testing (static vs. dynamic, gauge readings, manufacturer requirements); flow testing (flow meter readings, manufacturer flow requirements); drip mechanics (maximum tubing length, filtration and pressure regulation, emission devices, maintenance); and reading friction loss charts.

Blueprint trap: Because the domain titles are broad, candidates often assume "hydraulics" means only math. On the CIT, valves, sensors, drip components, and pressure/flow testing live inside the hydraulics domain, while pumps, water meters, backflow, leaks, and winterization live inside basic irrigation principles. Study the lettered topics, not the domain titles.

Fees, Retakes & Maintaining Certification

Current IA Fee Schedule

Each additional certification adds $25 to the annual renewal. Fees for testing outside North America are listed separately in the Certification Candidate Handbook.

Retake Policy

• No retake may be scheduled until the candidate has been officially notified of the previous result.
• No candidate may retake an exam until 90 days have passed.
• A candidate may sit the exam no more than three times within a two-year period. After an unsuccessful third attempt, the candidate must wait one year before re-applying.
• There is no refund for a failed exam, and failing to appear for a scheduled exam forfeits all fees.

Maintaining the Credential

1. Follow the Select Certified Code of Ethics.
2. Earn 20 continuing education credits every 2 years through IA courses, conferences, manufacturer training, and other approved professional development.
3. Pay the annual renewal fee — it is billed every year (invoice by Oct. 15, due Dec. 31), not once per two-year cycle. Late payment triggers a late fee; prolonged non-renewal lapses the certification and forces a full re-examination at the full exam fee.
