Hi Bonnie. If a nonprofit group wants to do work with Esri software, the should go to https://www.esri.com/nonprofit and fill out the application. NPOs get lightning low cost software, but have to qualify for that. If the group doing work is not a 501-c-3 nonprofit, they should talk with Esri sales (800-447-9778) to figure out the desired software elements and license quantity.
For K12 school instruction, it's easy -- free -- but the license with the lowest price has the greatest restrictions ... i.e. only for K12 and only for instruction of students or the teachers of K12 students. Everyone else works up the "ladder of permissions and price." Permissions generally expand with price; to get the greatest possible permissions (i.e. I can do anything I want with it) requires full-scale commercial price.
