Network for Astronomy School Education, NASE, is a project that is organizing courses for teachers throughout the entire world. The main objective of the project is to prepare secondary and primary school teachers in astronomy. Students love to know more about astronomy and teachers have the opportunity to observe the sky that every school has above it. Initially, this project is organizing courses for teachers. With the teachers who are highly motivated, working groups are created in order to continue their education in astronomy and sciences, and also to strengthen their relations with NASE and with each other. In this article we give details about the course, the contents, the complementary material for continuity, the structure of the working groups, and the countries in which we were beginning to work in 2010. There is also some information about future plans. (Contains 1 table and 6 figures.)
