To introduce the professional learning community (PLC) model to Thai teachers is the Thai government’s new initiative and hopefully, it promises a paradigm shift in Thailand’s educational reform. As early as the end of 1990 in the private sector, the PLC model originated in the United States, as team work and collaboration were proven to increase productivity. Later, it was adopted in the education sector as educators believed that learning culture in school plays a pivotal role in determining teachers’ success, simultaneously ensuring better student outcomes. Most Thai teachers used to work, think and prepare classes on their own. By adopting the PLC concept, the teachers’ job becomes different because it creates a community of like-minded professionals who can help one another by commenting on and critiquing each other’s practices by collaborating to improve their practices in order to solve common problems. Although a variety of ways to apply the PLC model has been done in Thai schools, private and government, the ones that have been most effective focus on how the students do or perform their work and their learning outcomes. This approach has a profound impact on teaching and learning because it shifts the focus from teachers to students.
