This document discusses why free and open source software (FOSS) matters to students. It notes that many important FOSS projects were started by students who had an "itch" they wanted to scratch by creating or contributing to software. The freedoms provided by FOSS, such as the freedom to use, study, modify and redistribute source code, empower students to learn programming skills and gain experience that can help them get jobs. Students are encouraged to find FOSS projects they are interested in and contribute in ways like coding, reporting bugs, writing documentation or spreading awareness of the software.
