Continued competence is defined by NDA as demonstrating knowledge, skills, or ability to proficiently perform as a certified demolition supervisor throughout the certificant’s professional career. Recertification of the CDS promotes continued competence throughout the certificant’s career in the demolition industry by requiring submission of continuing education units every three years.
