Abstract
This study investigates the development and validation of an integrated supervision system for English language teaching in Thai vocational education. Using a mixed-methods sequential design, the research collected quantitative data from 353 education professionals across vocational colleges and gathered qualitative validation from nine expert panelists. The study validated six core supervision components with 33 specific indicators organized across five operational dimensions: planning, implementation, data management, knowledge management, and evaluation. Analysis revealed significant gaps between current implementation levels ( = 4.02) and desired standards (
= 4.49). Expert validation confirmed high suitability of the integrated framework (
= 4.90), with improvement planning and collaborative evaluation receiving the highest validation scores (
= 4.94). Knowledge sharing meetings demonstrated the strongest current implementation (
= 4.10), while integrated data analytics showed the greatest need for enhancement (
= 3.39). Priority needs analysis identified critical development requirements in improvement planning and integrated data analytics (both PNI = 0.125), followed by collaborative planning (PNI = 0.123). Based on these findings, the study develops comprehensive guidelines for enhancing supervision practices, focusing on systematic integration of components, data-driven decision-making, and professional development support. This evidence-based framework provides practical guidance for improving vocational English language education in Thai educational contexts.
