This is the second of four monographs reporting the findings of Phase 2 of the International Association for the Evaluation of Educational Achievement (IEA) Preprimary Project, which presents data on the physical characteristics of children's early childhood settings. Early childhood settings were documented in the following 15 countries: (1) Belgium; (2) China; (3) Finland; (4) Greece; (5) Hong Kong; (6) Indonesia; (7) Ireland; (8) Italy; (9) Nigeria; (10) Poland; (11) Romania; (12) Slovenia; (13) Spain; (14) Thailand; and (15) United States. The monograph is divided into five sections. Section 1 provides a general introduction to the IEA/PPP's philosophy as well as information from the research literature about structural characteristics. Section 2 presents brief description profiles of early childhood care and education for each of the 15 countries focusing primarily on the status of settings serving 4-year-olds. Section 3 describes the study's methodology, including additional information about the instruments, sampling, and data collection for Phase 2, as well as a description of each country's sampling plan and data collection procedures. Section 4, chapters 5-10, reports the findings from the Provider Survey administered to the settings sampled in each country, in the areas of management policies and staffing, patterns of operation, physical characteristics, ancillary support services and parent involvement, teacher characteristics, and, from only Finland and United States, structural characteristics of family day care homes. The final section presents a summary of cross-national findings. Five appendices include the organized facility/group setting provider survey, the non-group/small-group setting provider survey questionnaire, supplementary tables, and a listing of national research centers and coordinators for Phase 2 of the project.
