INTEGRATING ISO 9712-BASED CERTIFICATION INTO PUBLIC SKILLS TRAINING INSTITUTIONS: A SYSTEMATIC LITERATURE REVIEW

Certification, Competency, Non-Destructive Testing, Personnel, TrainingAbstract
Non-Destructive Testing (NDT) plays a critical role in ensuring the safety, reliability, and quality of industrial assets, particularly in sectors where inspection decisions directly influence operational integrity and public safety. The competence of NDT personnel is therefore a major concern, as certification based on international standards such as ISO 9712 provides a structured mechanism for qualification, assessment, and professional recognition. However, despite the increasing importance of certified NDT personnel, limited systematic evidence has examined how ISO 9712-based certification can be integrated into public skills training institutions to strengthen personnel competence, training quality, and industrial readiness. This systematic literature review aims to analyze existing research related to NDT personnel certification, training, competency development, and quality-oriented certification practices. The review was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework. An advanced search strategy was applied in Scopus and Web of Science using the keywords “non-destructive testing”, “personnel”, “training”, “competency”, and “certification”. The search covered publications from 2016 to 2026. Following identification, screening, eligibility assessment, duplicate removal, and quality assessment, 22 primary studies were included in the final qualitative synthesis. The thematic analysis generated three major themes: NDT personnel certification, qualification, and competence assurance; NDT education, training, innovation, and competency development; and data-driven, quality-oriented NDE for certification and industrial assurance. The findings indicate that successful integration of ISO 9712-based certification into public skills training institutions requires alignment between certification standards, instructor capability, practical training resources, competency-based assessment, industrial collaboration, and emerging digital NDE practices. This review synthesizes fragmented evidence and proposes a clearer research direction to strengthen NDT certification pathways within public skills training systems.
