This study examines the quality of Hong Kong centre-based childcare services with the aim of identifying areas for further improvement. With the use of the Chinese version of the Infant/Toddler Environment Rating Scale-Revised (ITERS-R), the quality of the classrooms in nine non-profit centres located in different districts of Hong Kong was systematically assessed. The findings revealed the global quality of the childcare centres in Hong Kong and indicated the relative strengths and weaknesses of the specific areas of childcare services compared with findings from the international community. The results showed that the quality of centre-based care servicesfor infants and toddlers in Hong Kong was minimal. Compared to other countries, the health and safety practice in Hong Kong scored higher. However, the scores were especially low in space and furnishings, listening and talking, activities and programme structure. These results revealed that Hong Kong faced challenges with the quality of its centre-based care servicesin general. It was also surprising to find a negative correlation between the quality of the childcare centres and the teachers’ experience. The findings also indicated the importance of early childhood education training and continuous professional development. Copyright © 2019 The Author(s). All Rights Reserved.
