Certification Requirements

ASTM will grant certification only to those applicants who meet both of the following requirements: a passing grade on the ASTM written examination, and successful completion of the ASTM performance evaluation.
The performance examination requires actual demonstration of the required standards. The examinee is judged on their ability to correctly perform or describe all of the required procedures for each standard.
Recertification is necessary every five years and requires successful completion of both the written and performance examinations.

Certification registration and management is handled using the online platform Certemy. You will be prompted to either login or create a new account. After account log-in or creation, you will be prompted to complete steps of the certification program.

For Construction Materials Testing Certification Programs, written exams are scheduled during the second week of the month. Applicants are given access to the exam during that week and given one attempt to pass the exam.

Some exams may also be timed to follow live training courses. For those exams, check the description from the training course.

The exams are administered online using the Questionmark on-demand platform. This is a Web browser-based application and does not require installation of software on a personal computer.

Yes, all exams use Proctorio, a browser-based “Record and Review” application. Audio, video, and screen recordings are captured during the exam and reviewed by an ASTM exam administrator.

Proctorio is installed as a browser extension and only runs during an exam, meaning its access to the information on a test taker’s personal computer is limited and it cannot access personal files or change system settings. For more information on Proctorio and how your data is handled please refer to our FAQ on Online Proctoring.

Participants will need to meet the following system requirements:

• An Internet connection

• Google Chrome and the Proctorio Chrome extension

• A webcam

• A microphone

Yes, all Construction Materials Testing programs require that a qualified Supervisor/Manager completes a performance evaluation for each test method covered in the certification program. The performance logs to be used are provided to the Supervisor through the Certemy platform.

In the Certemy platform, the applicant must invite their Supervisor or Manager to register on the platform and complete the performance log steps on the applicant’s behalf.

The Supervisor/Manager conducting the performance evaluation must meet the requirements detailed for the applicable program.

ASTM Soil Laboratory Technician Level I - ASTM D3740 7.1, 7.2, or 7.3, whichever applicable

ASTM Asphalt Aggregates Laboratory Technician Level I - ASTM C1077 6.1.1 OR 6.1.2, whichever applicable

ASTM Asphalt Aggregates Laboratory Technician Level II - ASTM D3666 7.1 OR 7.2, whichever applicable

ASTM Asphalt Mixture Laboratory Technician - ASTM D3666 7.1 OR 7.2, whichever applicable

ASTM Asphalt Mixture Field Technician - ASTM D3666 7.1 OR 7.2, whichever applicable

After successful completion of all steps of the certification program, an official letter is emailed to the email address used to register. A digital credential is also issued through the Credly digital credentialing platform.
