In recent years, the United States has made substantial progress in the quality and availability of early childhood education (ECE), especially in the areas of special education and ECE programs for low-income families. Nonetheless, there is room for improvement in terms of access and quality. To improve access and quality in ECE, the United States can look to best practices in ECE in other countries. A total of 49 sources were reviewed to develop an in-depth understanding of both ECE in the United States and international ECE best practices. Sources were chosen based on relevance and quality and included books, articles, and policy reports. These sources covered the ECE best practices in increasing funding, access, and quality. From developed to developing countries, this review provides an understanding of best practices in ECE throughout the world that the United States can learn from to enhance ECE for the wellbeing of children as well as society.
