ACI Practice Test: What to Expect Before Exam Day

A quality ACI practice test mirrors the ACI Concrete Field Testing Technician Grade I exam, covering the seven ASTM standards you must perform and identify: C172, C231, C138, C143, C1064, C31, and C173/C173M. Expect roughly 55 multiple-choice questions with a 70% passing score, plus a separate hands-on performance evaluation judged by an ACI examiner.

How to Use an ACI Practice Test Effectively

Work through each practice question with the ACI CP-1 workbook open so you can trace wrong answers back to the exact ASTM procedure step. Focus repeat drills on slump tolerances, air content pressure-meter calibration, and unit weight calculations, since these are the areas most candidates miss on the first attempt.

ACI Certification Questions and Answers

What does ACI certification mean for concrete professionals?

ACI certification is a credential issued by the American Concrete Institute that validates a worker's knowledge and hands-on skills in concrete testing, inspection, or construction. It is recognized across the US construction industry and often required on DOT and federal projects. Programs include written exams and performance evaluations administered by local sponsoring groups.

How do you become ACI certified as a concrete field technician?

You must register with an ACI sponsoring group, complete a training session, then pass both a written exam (70% minimum) and a performance exam demonstrating seven ASTM field tests. Tests covered include slump, air content, temperature, unit weight, and making cylinders. Certification is valid for five years before requiring renewal.

How much does it cost to get ACI certified?

ACI certification typically costs between $200 and $400 depending on the program and local sponsoring group. The Concrete Field Testing Technician Grade I is the most common entry-level credential. Fees usually cover the training materials, written exam, and performance exam, but retake fees apply if you fail either portion.

What is the passing score for the ACI written exam?

The ACI Field Testing Technician Grade I written exam requires a minimum score of 70% to pass. It contains 55 multiple-choice and true/false questions covering seven ASTM standards. You have one hour to complete it, and you must also pass a separate hands-on performance exam on each ASTM procedure.

How long does ACI certification last before renewal?

ACI certifications are valid for five years from the date of issue. To renew, you must retake and pass both the written and performance exams before expiration. There is no continuing education pathway for renewal, so candidates must demonstrate current competency through full reexamination every cycle.

What ASTM tests are covered on the ACI Grade I exam?

The exam covers seven ASTM standards: C172 (sampling), C143 (slump), C231 (air content by pressure method), C173 (air content by volumetric method), C1064 (temperature), C138 (unit weight and yield), and C31 (making and curing test specimens). Candidates must demonstrate each procedure during the performance portion.

Is the ACI certification exam difficult to pass?

The ACI Grade I exam is considered moderately challenging, with first-time pass rates around 60-70%. Success depends heavily on studying the CP-1 workbook and practicing the hands-on ASTM procedures beforehand. Most failures occur on the performance portion when candidates skip steps or misuse equipment rather than on the written test.

Do I need ACI certification to work on concrete construction sites?

Many state DOT projects, federal contracts, and commercial specifications require ACI-certified technicians to perform field testing on fresh concrete. While not legally mandated for all concrete work, it is the industry standard credential and often a hiring requirement for quality control positions, inspection roles, and ready-mix producers across the United States.
