The purpose of this study was to explore the possibilities of ECERS (Early Childhood Environment Rating Scale) and SSTEW (Sustained Shared Thinking Emotional Well-being) between countries through defining the common characteristics of the Asia-Pacific region. Recently, discussions on the process quality in the quality of Early Childhood Education and Care (ECEC) have been increasing. At the same time, rating scales for process quality have been developed and become popularized. This study focused on ECERS-3 and SSTEW. In our previous study, we defined the common characteristics of the Asia-Pacific region through analyzing “Innovative Pedagogical Approaches in Early Childhood Care and Education” (UNESCO, 2015). That research led to considering the possibility of using ECERS-3 and SSTEW. There are two main findings. First, it has been used as evaluation tools prior to now, but this study identified the characteristics of ECEC across the Asia-Pacific region. Second, we suggested a new use for ECERS and SSTEW compared with the original version with respect to the capture of various characteristics. We captured the characteristics from watching video, in about ten minutes. In the original version, we had to observe for three-four hours, but our purpose was to explore the possibilities. Two scales were used and the results were judged valid when similar items were checked. Thus, this study served as a new try about rating scales.
