<![CDATA[Abstract School readiness is an essential factor for the academic success of primary school students, and children's social skills influence it, as well as teachers' understanding of transitional learning and parental support. This study examines students' school readiness, focusing on these three variables. Through a survey using tests, questionnaires, interviews and document analysis, this study was conducted among elementary school students in DKI Jakarta. It also developed a standardized school readiness instrument and a transition learning model for early-grade teachers. Results show that 50% of parents prioritize reading, 48.8% writing and 38.1% arithmetic as academic readiness. However, non-academic aspects such as disciplinary behaviour (98.8%), social skills (98.8%), emotion regulation (98.9%), independence (98.9%), and self-confidence (100%) were highly prioritized. In addition, 100% of parents supported a conducive educational atmosphere, teachers who respect students, a playful approach in the early grades, and fun learning media. In conclusion, school readiness covers academic and non-academic aspects in a balanced way, contributing to national policies to support developmentally appropriate transition learning in the early grades of primary school. The findings support Government policy in developing developmentally appropriate transition learning models for young children in the early grades of primary school.
