"They are rigorous, they’re about making sure our labs, personnel, and test methods conform, that they’re in compliance. They’re independent, not driven by a vendor or a construction company.”

Automated Alerts from the Proficiency Sample Program

Oct 06, 2022

Due to concerns with the accuracy of email alerts that are automatically generated through the Proficiency Sample Program for low ratings or failure to submit data, AASHTO re:source has suspended this notification service for AASHTO Accredited laboratories and registered specifiers. 

We are currently working to upgrade this system. Once it is functioning properly, the service will resume.

QUESTIONS
Accredited laboratories with questions can contact their Quality Analyst directly or email aap@aashtoresource.org.

Specifiers with questions, please email info@aashtoresource.org.
