The single most important factor in improving and sustaining a country's economy is its education system. In the past 3 decades, multinational corporations have invested in Costa Rica, which has focused on improving its education system, particularly to develop students who will acquire 21st-century skills and foundational knowledge in science, technology, engineering, and mathematics. Government policies require all schools to participate in the National Program of Science and Technology Fairs (PRONAFECYT), with a goal of equitable engagement by all students. The purpose of this study was to identify the role of educational leaders and government and business in implementation of and participation in the PRONAFECYT in primary schools in Costa Rica. The study examined leadership practices and the role of school leaders in development, implementation, and the overall impact of PRONAFECYT initiatives. The principle finding from comprehensive analysis was that leadership is integral to the success of the PRONAFECYT from all sectors in Costa Rica--government, business, and education. These partnerships have given Costa Rican students access to tools and opportunities to prepare to be competitive, knowledge- and technology-ready citizens. Other findings highlighted the need for greater access to resources, training, and professional development and ongoing leadership development for all stakeholders in the school system. The vision established by Costa Rica has been a catalyst for positive change in education. With continued support by the Ministry of Education and the Ministry of Science, Technology and Telecommunications, as well as private agencies such as the Costa Rica Investment Promotion Agency, the hope is for greater collaboration among all major corporations to ensure that Costa Rica continues to attract foreign direct investment and serve as an example for other countries to adapt similar policies and practices.
