Sampled — shipped under file-level sampling, not individually fact-checkedcommunity attestations: 0✓ / 0✗
Steps
Document at least 1 year of verifiable irrigation-related work experience before applying.
Agree to the Irrigation Association's Select Certified Code of Ethics as part of candidacy.
Study audit procedures, soil-plant relationships, irrigation scheduling, and audit equipment/technology.
Pass the 3-hour, 125-question multiple-choice exam at 70%+ (fees: $250 member / $495 nonmember).
Complete and submit proof of an independent irrigation audit if you want the credential to carry WaterSense recognition.
Submit 20 continuing education units per renewal cycle and pay the annual renewal fee ($75 member / $125 nonmember, plus $25 per additional IA certification).
Known gotchas
Passing the exam alone earns the CLIA credential, but it will NOT be WaterSense-recognized unless you separately submit proof of a completed independent audit to the IA.
Renewal fees and CEU requirements are tracked on an ongoing cycle — confirm the current IA renewal cadence directly before assuming a fixed grace period.
