In an effort to maximize our available space and to more efficiently utilize our Supplemental Examiners, the Colorado Ready Mixed Concrete Association will be conducting Aggregate Testing Technician—Level 2, Aggregate Base Testing Technician, Laboratory Testing Technician—Level 2, and Self-Consolidating Concrete Testing Technician exams at the same time on the same dates. These sessions are referred to as Advanced Lab sessions, and the capacity listed is the total capacity for the day which will be shared across all four exams. Examinees can register for up to two different exams on these dates if desired.
