Hello Rolf,
Debian Outreachy is an internship program for people to work on Debian. What you're probably interested in is Debian(
https://www.debian.org/), a GNU Linux distribution focused on stability and freedom as defined by the FSF (although there is a non free repository available if need be).
Debian is free to use and distribute and comes with a selection of 59,000 software packages that you can download to fit your needs.
Best,
Rishabh Tewari
Currently the school where I am a governor uses a Windows OS, which is
expensive. We are under financial pressure and I am investigating the
possibility of moving the schools OS to a Linux distro. Is the Debian
Outreach project relevant to us?
Regards,
Rolf Clayton
