Thailand's government is pursuing OECD membership with a 2028 target, framing the drive not merely as gaining status but as a systematic reform vehicle. Key initiatives span economic, tax, labor, digital, education, and public administration policies across 34 government agencies. PISA 2025 results show modest educational gains (science +23 points, math +13, reading +13 from 2022), signaling traction on human capital development—a cornerstone of competitive positioning. The pathway hinges on technical committee assessments and legislative alignment with OECD standards.
