The aim of the present research is to clarify the current curriculum used by early childhood education and care centers. To achieve this objective, questionnaire surveys were carried out at the early childhood education and care centers in Japan. The results revealed that (1) about 10% of all centers still do not have a curriculum, (2) only 30% of childcare workers are involved in the creation of a curriculum, and (3) over 10% of childcare workers participate in childcare activities without awareness of the curriculum. To ensure and enhance the quality of early childhood education and care, in addition to having a thorough awareness of the curriculum, childcare workers should be encouraged to participate in creating the curriculum.
