NDT (Non-Destructive Testing) trained personnel can be classified primarily by their certification levels because these certifications are established by recognized standards and indicate the individual's competency in various NDT methods. Certification levels provide a structured framework that categorizes personnel based on their training, knowledge, and practical skills in specific techniques, such as ultrasonics, radiography, magnetic particle testing, and others. These levels allow employers to assess whether an individual is qualified to perform certain tasks safely and effectively, ensuring compliance with industry standards and safety regulations.

While experience, department assignments, and educational background are relevant factors, they do not provide the same standardized measure of proficiency and capability as certification levels do. The system of certification allows for a clear and consistent way to evaluate competencies across the workforce in the NDT field. This focus on certification ensures that personnel are capable of performing the essential functions required in their roles, making it the most definitive method of classification.
