SCOPE AND KNOWLEDGE
This program requires demonstration of the knowledge and hands-on skills covered on the Job Task Analysis (JTA):
Job Task Analysis (JTA) for ACI Masonry Laboratory Testing Technician Certification
The program requires a working knowledge of laboratory procedures selected from the following ASTM test methods and practices:
-
C90 – 23—Loadbearing Concrete Masonry Units
-
C140/C140M – 23a—Sampling and Testing Concrete Masonry Units and Related Units
-
C270– 24—Mortar for Unit Masonry
-
C780 – 23 including Annex—Preconstruction and Construction Evaluation of Mortars for Plain and Reinforced Unit Masonry
-
C1019 – 24—Sampling and Testing Grout
-
C1314 – 23b—Compressive Strength of Masonry Prisms
-
C1552 – 23a—Capping Concrete Masonry Units, Related Units and Masonry Prisms for Compression Testing
Supplemental resources that may aid you in this program are:
-
C39/C39M—Compressive Strength of Cylindrical Concrete Specimens
-
C109/C109M—Compressive Strength of Hydraulic Cement Mortars (Using 2-in. or [50-mm] Cube Specimens)
-
C617/C617M—Capping Cylindrical Concrete Specimens
CERTIFICATION REQUIREMENTS
ACI will grant certification only to those applicants who meet both of the following requirements:
-
A passing grade on the ACI written examination; AND
-
Successful completion of the ACI performance examination.
The one-and-a-half hour written examination is open-book and consists of approximately 70 multiple-choice questions. There are between eight and 12 questions on each of the ASTM test methods and practices. To pass the written examination, BOTH of the following conditions must be met:
-
At least 60% correct for each of the required test methods and practices; AND
-
A minimum score of 70% overall.
The performance examination is closed-book and requires actual demonstration of select field procedures described in ASTM test methods C140/C140M, C780, C1019, and C1552. The examinee is judged on his/her ability to correctly perform (or describe, where allowed) required steps for each procedure.
Recertification is necessary every five years and requires successful completion of both the written and performance examinations.
AMERICANS WITH DISABILITY ACT
Individuals requesting special accommodations enabling them to participate in ACI certification examinations must submit a letter from their primary physician to the Las Vegas Chapter ACI describing the physical challenge and providing a proposed solution (i.e. more time, a reader for the questions, physical assistance, etc.). The Las Vegas Chapter ACI will forward the request and physician’s letter to ACI for direction. Since the notification and formulation of appropriate accommodations takes time, candidates must make their request and submit the physician letter to the Las Vegas Chapter ACI at least three weeks prior to a certification examination session to formulate appropriate accommodations, arrange for their availability at the session, and accept the registration.
CANCELLATION POLICY
Participants may cancel or transfer their registration to another session by emailing: [email protected] no later than 7 business days before the testing session.
- Cancellations will receive a refund of the registration fee minus a $100 cancellation fee.
- Transfers will be issued a coupon code for the registration fee less a $30 transfer fee which is valid for one year from the date of issuance. This code may be used for any future certification or training.
