Frequently Asked Questions
How many questions are on the NICET CMT-Concrete exam?
NICET lists CMT-Concrete as 110 questions in 170 minutes at Level I, 165 questions in 350 minutes at Level II (including a 30-minute scheduled break), 138 questions in 380 minutes at Level III, and 88 items in 230 minutes at Level IV. Check the NICET CMT-Concrete program page before scheduling.
How much does the NICET CMT-Concrete exam cost in 2026?
Per the 2026 NICET standard-model CMT fee schedule, Level I is $230, Level II $315, Level III $370, and Level IV $425. Rescheduling more than 24 hours in advance within the testing window is generally free; late changes may trigger fees.
Who administers the CMT-Concrete exam?
NICET owns the certification and Pearson VUE delivers the computer-based test at approved test centers. Candidates register through NICET, receive an eligibility notice, and then schedule with Pearson VUE.
What work experience does NICET require for each CMT-Concrete level?
Per NICET certification requirements, Level I needs 6 months of direct CMT involvement (3 in concrete), Level II 24 months (12 in concrete), Level III 60 months (36 in concrete) plus a personal recommendation, and Level IV 120 months (60 in concrete) plus a senior-level recommendation.
Which standards should I study for CMT-Concrete Level I?
NICET's Level I outline emphasizes ASTM C31 (specimens), C39 (compressive strength), C138 (unit weight/yield), C143 (slump), C172 (sampling), C231/C173 (air content), C1064 (temperature), and C136 (gradation), plus ACI 301/318 basics on acceptance, curing, and placement.
How do Level III and IV differ from Level I/II?
Level III and IV shift from running routine tests to designing sampling programs, reviewing lower-level technicians, running advanced tests (chloride permeability, maturity, freeze-thaw, post-tensioning/prestress inspections), maintaining calibration/training records, and preparing reports.
How often do I need to recertify NICET CMT-Concrete?
NICET certifications are recertified every three years through Continuing Professional Development. Candidates accrue CPD points from technical training, professional activity, and supervised experience, then submit the record before the cycle ends.
What is a practice question that actually trains for the exam?
Expect calculations (w/cm, relative strength, air voids), ASTM procedure details (layer counts for slump and cylinder casting, 5 +/- 2 second cone lift, 35 +/- 7 psi/s load rate), ACI 318 acceptance (average of 3 tests vs. 500 psi rule), inspector ethics, and plant/delivery ticket questions.
