Distributing a product license means giving the license to another administrator or teacher.
Assigning a license means giving a specific student access to an app, like My Math Academy or ABCmouse.
For example, an administrator might distribute 20 licenses to a teacher. The teacher can then assign those 20 licenses to her students.
Note: Distributing a license doesn’t assign it. Once licenses are distributed to another person, that person must then assign the license to a student.
