Despite emerging evidence of the contributors to high-quality family day care, a comprehensive comparison of international family day care systems has not been undertaken. The aim of this paper is to compare regulated family day care (FDC) in Australia, Canada, England and Wales, Germany, Ireland, Japan, Norway, New Zealand, Sweden, and the USA, using standard information about FDC usage and each country's structural characteristics, regulatory approach, quality assurance indicators, supervision and support, and sector challenges. A template was developed by representatives of the International Family Day Care Organisation, including academics, FDC providers, and FDC educators and management staff. The paper demonstrates that, although the existing body of published research is sufficient to provide clear guidance for developing and maintaining quality FDC, this knowledge is not always being applied in current practices. Three practices, each pertaining to several countries, are of concern: (a) minimal requirements for being a regulated FDC provider, (b) minimal quality assurance guidelines, and (c) minimal provider supports. There is great potential to learn from countries that have a high level of success in providing high-quality FDC and strong support for providers and families. (author abstract)
