This publication provides a source of information and research to the people interested in and responsible for American Sponsored Overseas Schools (ASOS). The first section includes an overview of six major categories of research, namely: school setting, school institutionalization; school organization and administration, school program, personnel, and pupils. Each category is treated by three approaches: (a) one or more vignettes to provide fictionalized but illustrative examples of the human element in the ASOS; (b) sets of the author's premises and examples which illustrate the ambiance in which the schools exist, and (c) a narrative providing a conspectus of the included research about the ASOS as related to the major category. The second section discusses the research matrix, said to provide a ready reference to many of the common problems and potentials in the ASOS. Included here are the coding system, regional code, simplified coding system, matrix outline, school setting, institutionalization, organization and administration, school program, personnel and pupils. This model classifying pertinent research is considered to provide the serious researcher not only with a means of classifying existing research but also for identifying the voids in the research base.
