NICET CPD

NICET's Geotechnical Engineering Technology program (Field Code 009) uses a work-element examination model: candidates pick from General work elements (math, safety, soil classification, handling samples, moisture content) and Special work elements in Construction (field density by sand cone/rubber balloon/drive cylinder/nuclear, moisture-density, subgrade preparation), Exploration (SPT and Shelby tube sampling, boring logs, auger and rotary drilling, rock coring), and Laboratory (Atterberg limits, sieve analysis, CBR, triaxial, permeability, specific gravity). Level I requires 8 work elements, Level II 30, Level III up to 48, and Level IV up to 84 in the Generalist track. Level IV additionally requires a senior-responsibility project write-up, and Level III requires a personal recommendation.

1Which ASTM standard defines the standard terminology used for soil and rock in the NICET Geotechnical program?

A.ASTM D653

B.ASTM D2488

C.ASTM D2216

D.ASTM D698

Explanation: ASTM D653 is the Standard Terminology Relating to Soil, Rock, and Contained Fluids. NICET work element 11004 requires knowledge of these standardized definitions.

2Which ASTM standard specifies the laboratory determination of moisture (water) content of soil?

A.D2216

B.D4318

C.D422

D.D854

Explanation: ASTM D2216 establishes oven-drying at 110 +/- 5 degrees C as the standard laboratory method for water content of soil and rock.

3Per ASTM D4220, why are undisturbed cohesive samples typically sealed with wax and kept upright during transport?

A.To reduce shipping cost

B.To preserve in-situ moisture and structure

C.To accelerate consolidation in the lab

D.To force drainage of excess pore water

Explanation: ASTM D4220 Group C/D preservation is used to protect natural water content and soil structure so lab strength and consolidation results reflect in-situ conditions.

4Under OSHA 29 CFR 1926 Subpart P, which soil type is the most stable for excavation purposes?

A.Type A

B.Type B

C.Type C

D.Previously disturbed soil

Explanation: OSHA classifies soils as A, B, or C with A being the most stable (typically cohesive with unconfined compressive strength at least 1.5 tsf). Previously disturbed soil is automatically Type C.

5At what excavation depth does OSHA generally require a protective system such as sloping, shoring, or shielding?

A.3 feet

B.5 feet

C.8 feet

D.12 feet

Explanation: OSHA 1926.652 requires protective systems for excavations 5 feet or deeper unless the excavation is entirely in stable rock. Below 5 feet, a competent person may determine systems are unnecessary.

6A soil sample has a wet mass of 180.0 g and a dry mass of 150.0 g. What is the water content?

A.16.7%

B.20.0%

C.25.0%

D.83.3%

Explanation: Water content w = (Mw / Ms) x 100 = (180 - 150)/150 x 100 = 30/150 x 100 = 20.0 percent. ASTM D2216 uses dry soil mass in the denominator, not wet mass.

7For a saturated soil, which weight-volume equation is correct?

A.e = Gs * w (saturation equation, S=1)

B.n = 1 + e

C.Gs = gamma_d / gamma_w * (1 - n)

D.w = Gs / e

Explanation: For saturated soils, Se = Gs*w reduces to e = Gs*w when S = 1 (100 percent saturation). This is a foundational weight-volume relationship.

8In ASTM D653 terminology, what is 'liquid limit' (LL)?

A.The water content at which soil changes from plastic to liquid behavior

B.The water content at zero shear strength

C.The density at which soil is fully saturated

D.The void ratio at failure

Explanation: The liquid limit is the water content above which soil behaves as a viscous fluid. It is determined per ASTM D4318 using the Casagrande cup or fall-cone method.

9Why should a field technician never alter raw test data on an original field log, even if a reading appears wrong?

A.Altered data compromises the legal record and traceability

B.Erasers are banned on all NICET exams

C.Raw data always becomes correct after averaging

D.Lab supervisors prefer handwritten originals

Explanation: Original field logs are legal records. Corrections should be a single line-out with initials, date, and a note, never erasure, to preserve evidentiary integrity.

10A confined-space permit-required entry must include atmospheric testing for all of the following EXCEPT:

A.Oxygen content

B.Flammable gases and vapors

C.Toxic airborne contaminants

D.Ambient noise level

Explanation: OSHA 1910.146 requires atmospheric monitoring in the order oxygen, flammables, then toxics. Noise monitoring is a separate 1910.95 consideration and not part of the confined-space atmospheric test.

NICET Geotech Study Tips from Top Performers

1Memorize the paired ASTM D-numbers for each field and lab test because questions often reference the standard by number rather than by the full test name.

2Know the default procedures for SPT (D1586) and Shelby tube sampling (D1587) cold, including hammer weight, drop height, 18-inch penetration, N-value computation, and when Shelby tubes are preferred for undisturbed cohesive samples.

3Compare the four field density methods (sand cone, rubber balloon, drive cylinder, nuclear) on cost, moisture measurement, correction factors, and soil types where each is preferred.

4Drill USCS classification workflow: gradation curve, Cu and Cc, Atterberg limits, and the plasticity chart with the A-line and U-line.

5Be confident computing Atterberg limits (LL, PL, PI) and weight-volume relationships (e, n, w, Gs, gamma-d, gamma-sat, Sr) from raw lab data.

6Practice reading boring logs: split the header info, stratigraphy, sample types, SPT N-values, water level symbols, and lab test callouts.

7Learn OSHA excavation and trenching basics including soil type classifications A/B/C, sloping and shoring, and the competent person role even if the sitting is Exploration or Laboratory focused.

8For Level III/IV prep, shift practice toward interpreting data, writing summary reports, managing junior technicians, quality assurance, and project-level judgment rather than individual test mechanics.

Frequently Asked Questions

How is the NICET Geotechnical Engineering Technology exam structured?

NICET uses a work-element model for this program. Candidates select individual work elements covering math, safety, classification, sampling, field testing, lab testing, and reporting, and each work element is scored separately. Level I needs 8 passed work elements, Level II 30, Level III 44-48 depending on subfield, and Level IV up to 84 for the Generalist track. No more than 34 work elements can be scheduled in a single sitting.

What are the NICET Geotech subfields?

The program recognizes three subfields plus a Generalist track. Construction covers in-place density, compaction, and on-site quality control. Exploration covers drilling, SPT and Shelby tube sampling, boring logs, and groundwater monitoring. Laboratory covers index, strength, and permeability testing. Generalist is for technicians who routinely work across all three areas.

How much does the NICET Geotech exam cost?

NICET's current CBT pricing model lists Level I at $230, Level II at $315, Level III at $370, and Level IV at $425. Legacy program applicants should verify the current fee with NICET before scheduling.

What work experience is required for NICET Geotech certification?

Level I is designed for entry-level technicians with limited experience. NICET recommends technicians with 18 or more months of relevant experience start at Level II. Level III certification requires a personal recommendation, and Level IV requires a written major-project write-up documenting senior responsibility on a major geotechnical construction project.

What ASTM standards should I study for NICET Geotech?

Core standards include D653 (terminology), D2216 (moisture content), D2488 (visual classification), D2487 (USCS classification), D4318 (Atterberg limits), D422 (particle size), D698/D1557 (Proctor compaction), D1556/D2167/D2937/D6938 (field density methods), D1586 (SPT), D1587 (Shelby tube), D4220 (sample handling), D2166 (unconfined compression), D2850 (UU triaxial), D2434 (permeability), D854 (specific gravity), and D4253/D4254 (relative density).

What reference sources are used on the NICET Geotech exam?

NICET permits the standards and procedures cited in each work element description at the test site. In practice, this includes ASTM D-series soil testing standards, AASHTO T-series methods, OSHA 2202 and 2207, the Unified Soil Classification System, and AASHTO soil classification. Candidates should be fluent in finding information in these documents, not just memorizing numbers.

Is NICET Geotech the same as CMT Soils?

No. Geotechnical Engineering Technology (Field Code 009) is a separate, broader legacy program covering exploration, construction, and lab work, while Construction Materials Testing - Soils is a newer Standard Model/CBT program focused on construction materials quality. Many technicians pursue both because some work elements crossover.

How often do I need to recertify?

NICET certifications must be recertified every three years through Continuing Professional Development. Annual renewal fees must also be paid; if a yearly payment is missed for three consecutive calendar years, the certification expires and must be earned again as a new applicant.
