Concrete Field Inspector Recertification (CFIR)
Prerequisites for Concrete Field Inspector recertification
- Your Concrete Field Inspector Certification must still be current for you to take the recertification course.
- If you hold a Tester and Inspector level certification, the Inspector recertification class will update both certifications, although MnDOT only for CFTC.
- Students who complete this Inspector Recertification course will also be recertified with a MnDOT (not ACI) Concrete Field Tester Certification.
Specific Situations
- If you need to recertify in both Concrete Field Inspector and Concrete Field Tester (MnDOT only – not ACI), take this class.
- If you only need a MnDOT Concrete Field Tester certification (not ACI and not Inspector), take the Concrete Field Tester Recertification eLearning (new in 2023-2024).
- If you need ACI Concrete Field-Testing Technician Grade 1 certification, you must retake the full ACI Concrete Field Tester initial certification class.
Expiration and recertification options
- This certification expires after five seasons.
- A recertification must be completed before the end of the fifth training season.
- If your certification has recently expired and you have relevant work experience, you may apply to regain MnDOT certification through a Recently Expired Certification Exam. Otherwise, you must take the initial certification course again to regain certification.
