Schools are a proving ground for students. Children develop habits of all sorts while they expand their understanding of the world. Schools need to provide tools for students which give them flexibility and increasing self direction.
That makes school a perfect place to install tools that students can use both within the classroom and at home.
Migrating from proprietary office suites to LibreOffice has some issues, of course. So it is great to read information which makes it easier.
LibreOffice is a community-developed tool, steadily driving forward in capabilities. It costs only the effort to install on every computer in your school district. Make it a part of the hard drive image for your school.
