The Informal Artisan Training System (IATS) is crucial to Ghana’s construction industry but faces challenges that affect the quality of skilled labour and project outcomes. While research has documented the general limitations of informal artisan training, limited focus has been given to analysing specific learning patterns of artisans and their impact on project outcomes. This study addresses this gap by examining these learning patterns and evaluating their direct influence on construction project outcomes in Ghana. Through a mixed-methods approach, data were collected from 314 participants, including apprentice artisans, master artisans, and construction supervisors, using surveys and field interactions. Findings identified two training approaches: traditional and attachment-based apprenticeship, with significant deficiencies in technical skills, formal education, and apprentices’ readiness for independent work. Master artisans are committed to ongoing learning but rely heavily on practical experience. Construction supervisors recognize the IATS’s role in meeting industry needs but highlight persistent skill gaps affecting productivity. By recommending formalization and standardization, this study underscores the importance of aligning artisan skills with industry standards, ensuring that training outcomes directly support the construction industry’s quality and productivity benchmarks. This study provides actionable insights for improving artisan training and deepens understanding of informal training dynamics. © 2025 Informa UK Limited, trading as Taylor & Francis Group.
