Questionnaires were sent to the Ministries of Education in 69 countries to obtain information about one-teacher school systems in each respective country. The questionnaire was constructed to provide information about administration, length of schooling in one-teacher schools, organization of school work, curricula and methods, teaching staff, miscellaneous topics, and relevant statistical information. An analysis of responses to the questionnaire indicated that: four-fifths of the countries used a one-teacher school system to some extent; the proportion of teachers working in one-teacher schools varied from 0.1 percent to 47 percent; there was a tendency to decrease one-teacher schools; seven-tenths of the countries reported that the one-teacher school covered as many years schooling as a primary school with several teachers; and teacher salaries were in general equal to salaries in other primary schools.
