This study examines how the In-Country Value (ICV) strategy affects Omanisation and human capital development in Oman’s oil and gas sector. Based on the resource-based view, the research uses a descriptive approach and surveys 65 purposively selected employees from four major companies. Partial least squares structural equation modelling (PLS-SEM) shows that ICV initiatives significantly improve in-job training and Omanisation outcomes, accounting for over 70% of the variance in workforce qualification. The findings add to the literature on local content policies by demonstrating how ICV can build dynamic capabilities and competitive advantage in emerging economies. Practical implications for policymakers and industry leaders are discussed. The study finds a positive link between the acceptance of training and development initiatives, such as In-Job Training, the Omanisation Plan, and the ICV strategy, thereby supporting the overall enhancement of Omanisation and the training and development of the Omani workforce. These results confirm the effectiveness of implementing ICV strategies in promoting workforce development and aligning with the country's value strategy objectives. The research offers valuable insights for policymakers, industry practitioners, and researchers interested in ICV and human resources development within the context of Oman.
