About this exam
The ACI Concrete Laboratory Testing Technician—Level 1 Exam is for people who test concrete in a laboratory and need to demonstrate knowledge of standard testing procedures. It is relevant to laboratory technicians, materials inspectors, and engineers involved in concrete quality control. Certification focuses on practical competence and understanding of test methods; it is not an academic admissions exam. Candidates should check ACI’s current program information and their local sponsoring group for the latest eligibility and examination requirements.
Preparation covers both the reasoning behind laboratory procedures and the steps used to perform them correctly. Key areas include fresh concrete sampling and handling under ASTM C172, laboratory batching and mixing under ASTM C192, slump testing under ASTM C143, and temperature measurement under ASTM C1064. Review equipment, procedural requirements, measurement and recording, and common sources of error. For 2027–2028 preparation, confirm the current ACI materials, since exam details and local arrangements may change.
How to Prepare for the ACI Concrete Laboratory Testing Technician—Level 1 Exam
- Study the applicable ASTM procedures, especially C172, C192, C143, and C1064; focus on the correct sequence, equipment, measurements, and documentation for each method.
- Rehearse each procedure as a practical task, explaining why each step matters and identifying handling or measurement errors that could affect results.
- Use timed multiple-choice practice to check recall, then review every missed question against the current ACI exam information and relevant ASTM standards.
