The purpose of this study was to investigate the understanding situation, the cooperative levels, and related opinions of childcare workers regarding the integration plan of kindergartens and daycare centers by a nation-wide survey. 1,370 childcare workers wee recruited by the cluster sampling technique. Among them 1,071 were from public daycare centers, while 299 were from private ones. Analysis from the available data revealed the following findings. First, childcare workers from private daycare centers had a higher understanding level on the integration plan than those from public ones. A significant difference regarding the understanding level on the international plan was found between childcare workers from urban areas and from the remote districts. Secondly, the childcare workers’ knowledge about the integration plan was mostly from newspapers, TV programs, and from conversations toward their colleagues. Nearly 90% of the childcare workers had never participated in any public hearings regarding the plan. Thirdly, childcare workers’ educational background and seniority are both significantly correlated with the understanding and cooperative levels. Fourthly, childcare workers showed a relevant level of understanding and cooperation of the integration plan in regards to the detailed integrating policies, such as the change of government’s supervising agency, childcare workers’ qualification, personnel welfare, and the future directions of running a childcare center.
