Coarse Aggregate Level 1 Technician

The Coarse Aggregate (CA) Level 1: Sampling and Grading Course is intended to assure competency in issues affecting QC/QA for aggregate suppliers. This course serves as the primary certification required of all aggregate QC technicians and focuses on field sampling, sample reduction, and grading.

Course Outline: 
There is no instruction included in this course.  Participants are required to take a written exam administered at the course site and achieve a score of 80% or higher to become certified.  The exam is open notes and open book.  Upon registration AND payment for the course, each participant will be sent a course manual to be used for the exam. 

Entry Requirements/What to Expect:


  • Experience form signed by:
