Recent studies have shown that a solid educational foundation is of great importance to children's lives and their ability to grow and adapt to the demands of a changing world. An increased demand for education and care programs for preschool children has evolved and since most governments do not provide support at this level, the United Nations Educational, Scientific, and Cultural Organization (UNESCO) produces materials and trains teachers to meet this need. This final report provides the background, the steps followed, and the conclusions and recommendations of the workshop developed by OREALC (Regional Office of Education for Latin America and the Caribbean) to improve the education and care given to children aged seven and younger in the region. The objectives of the workshop were: (1) to identify criteria used in selecting and adapting materials for use in preschool education programs; (2) to prepare materials for potential use by different groups; and (3) to establish a process of testing and evaluation that would indicate how the results of the testing would be used. The participants in the workshop represented Argentina, Bolivia, Brazil, Chile, Colombia, Costa Rica, Ecuador, Guatemala, Panama, Paraguay, Peru, Dominican Republic, Uruguay and Venezuela. Representatives from national and international organizations were also present. The report lists 16 conclusions and 10 recommendations made by the participants along with 6 conclusions made by UNESCO and UNICEF. The names and addresses of participants, an outline of the workshop's agenda, a bibliography of materials arranged by participating countries, and a chart of the potential uses of the materials are included.
