NETTCP SoilsAggregate Lab Technician Certification Exam

NETTCP Soils Aggregate Lab Technician Sieve analysis, compaction testing, and gradation curves aren’t abstractions—you’ll perform them hands-on in the lab. Brush up on soil classification systems (AASHTO, USDA), particle size distribution methods, and how moisture content affects aggregate behavior. The exam expects familiarity with standard test procedures like Proctor compaction and California bearing ratio protocols. Weak spots in basic lab safety or metric conversions tend to trip unprepared candidates.
