This Spanish-language report (with an English summary) describes a course on interagency cooperation held at the Golda Meir Mount Carmel International Training Center in Haifa, Israel. The course, with 30 Central and South American participants, discusses the necessity of pooling resources and sharing responsibility among institutions in various sectors in order to improve the quality of preschool education through taking better advantage of human and material resources. The course was the third of its kind; basic admission requirements were university studies and a minimum of 8 years work experience. The program consisted of lectures, study visits, workshops, and discussions in heterogeneous groups based on countries and professional functions. The 8-week course began with introductory lectures, which were then expanded theoretically and through observation visits, in order to strengthen the relationship between concepts and practice. Workshops analyzed different professional functions and the possibilities and techniques for cooperation between functions. At the end of the course, each participant presented, both orally and in writing, a project proposal in the field of early childhood education which she considered applicable in her work setting. In many cases, coordination between different institutions was introduced, in order to optimize project results. (Author/EV)
