STRENGTH AGG

• Certification/recertification requires successful completion of both the written and performance examinations.
• Certifications are valid for a period of five years from the date of successfully completing all requirements.
• Exams are scored by ACI and results & certification records are solely maintained by them. CRMCA does not have exam scores, results, or certification records. 

Strength Agg Exams are staggered exam sessions which allow registrants to register for and take either or both of these exams during a single session (click on an exam title to learn more about that certification):
