Personal and social development is an important area which influences children's learning journey in all levels of education. Examining the impact of the arts on children's development, there are several studies that adopt this focus. However, the majority of them focus on either primary or secondary education or on specific personal and social skills through a structured intervention, which is not compatible with the liberal context of the arts. Considering the importance of this area and the statement above, this research project was designed. The purpose of this paper was to examine the effects of a child-led art intervention in children's personal and social development in the early years settings. The intervention used the 'Play and Learn through the Arts' (PLA) programme for a full school year. The participants were from a case study of a Greek early years setting with 5--6-year-old children. Informed consent was obtained from all participants included in the study. The findings revealed a positive influence of the arts, and more specifically of the PLA, on children's personal and social skills.
