The Fermi Masterclass is an international program offered to high-school students to study cosmic objects by performing basic analyses of Fermi-LAT data using professional software and direct guidance of scientists from the Fermi Collaboration. This project draws from the Masterclass program organized by the CERN International Particle Physics Outreach Group (IPPOG), involving thousands of students across the world. The Fermi Masterclasses take advantage of the unique properties of the Fermi-LAT data: they are public, all-sky, promptly available and fairly simple to understand. Building on the Fermi Science Tools distributed by the Science Support Center, several groups in different countries have developed software tools and examples to allow simple inspection and analyses of Fermi data by non-experts, and organized Masterclasses focusing on different science topics over the past years. Following the success of the program, more events are foreseen in the future, possibly under the framework of IPPOG network.
