Who regulates backflow tester certification in Indiana

Certification is regulated at the state level: one credential is valid across Indiana.

The authority for backflow tester credentials in Indiana is Indiana Department of Environmental Management (IDEM), Cross Connection Control and Backflow Prevention Program. Credential: "cross connection control device inspector" (IDEM materials also use "Backflow Prevention Assembly Tester"), under 327 IAC 8-10-11. The registration number itself does not expire; only "Active" list status requires returning the biennial form. IDEM is the certifying authority, not the Professional Licensing Agency (PLA) (mylicense.in.gov is only a verification lookup). No CE is required for renewal; initial registration requires a 40-hour course plus written/oral exam. A circulating third-party claim of a "3-year recertification with ASSE exam" conflicts with the official regulation and renewal form and was excluded.

How often you need to renew

Backflow tester certification in Indiana must be renewed every 2 years (Active Indiana Inspector status reconfirmed every even-numbered year, Jan 1 - Dec 31; a status-renewal filing, not retraining or re-exam).

Continuing education and retesting requirements

Indiana Department of Environmental Management (IDEM), Cross Connection Control and Backflow Prevention Program does not publish continuing education requirements online. Confirm with the agency before your renewal date.

Renewal deadline and grace period

The agency does not publish a formal grace period online. Treat your expiration date as hard: Water purveyors generally stop accepting test reports from testers whose certification has lapsed, and many jurisdictions require retaking the full certification course instead of a simple renewal once the credential expires. Confirm the exact grace period, if any, with Indiana Department of Environmental Management (IDEM), Cross Connection Control and Backflow Prevention Program well before your expiration date.

How to renew, step by step

  1. Confirm your exact expiration date on your certification card or with Indiana Department of Environmental Management (IDEM), Cross Connection Control and Backflow Prevention Program.
  2. Complete any required refresher course or continuing education for your jurisdiction.
  3. Submit the renewal application to the agency before the deadline.
  4. Keep your test kit calibration certificate current: most jurisdictions require annual gauge calibration alongside a valid tester credential.
