Please note this is not a training class and there is no examination at the scheduled Program Procedure meeting.  Attendance to the Program Procedure meeting is MANDATORY, as study material will be handed out at this meeting.  Please sign up for ONE Program Procedure meeting (April, July, or October).  The performance examinations will be held at each applicant's respective laboratory, or a lab of ACI’s choice and a schedule of all examinations (written and performance) will be determined during the Program Procedure meeting.  All applications and fees must be received at least 14 days prior to the Program Procedure meeting and pre-registration is mandatory.

Please join us this year to become part of the certified technicians of standards that we strive to uphold.  Experience and knowledge of concrete testing of the previously mentioned ASTM/AASHTO procedures is highly recommended.
