Districts don't "adopt" Edlink. To say that another way, they don't have to become "Edlink" districts. Edlink is, where we can be, transparent to the end-user (educators and learners). There are already so many brands in the mix - we don't need or want to add to the confusion of the ecosystem. We just want to solve hard problems for hardworking edtech apps, developers, teachers and students.
However, Edlink is currently supporting over 1,250 school districts and universities as of this writing.
