Welcome to the Arizona Technical Testing Institute

  The Arizona Technical Testing Institute (ATTI) is a nonprofit organization formed to promote the highest standard in highway construction materials sampling and testing through certification technicians.

  ATTI certification emphasizes a hands-on approach, that is, technicians must satisfactorily perform test methods as well as pass a written exam to receive certification. The organization is represented by members from the Arizona Department of Transportation (ADOT), highway contractors, materials suppliers, materials testing laboratories, Arizona Rock Products Association (ARPA), and Associated General Contractors (AGC).
