Does your program run half day or full day? Do you think ECE program intensity (hours per week) impact child development in different domains? ECE programs all over the world have different program intensities. A recent study by Rao et al. (2019) suggests that the relation between ECE program intensity and child development varies across different ethnic and socioeconomic status groups. Among their four focal countries in East Asia and the Pacific, the intensity of ECE is associated with better language development in Mongolia and Cambodia but lower socio-emotional scores in Cambodia and China. If you are interested in this finding, make sure you read their article listed below.
