Since Apple has opened the Device Enrollment Program to school districts, the need for individual students to create free Apple IDs has diminished some. If you haven’t explored the DEP and your district has more than a cart of iPads or MacBooks, you should seriously consider doing so. Apple brings many management features that makes these devices much easier to manage. You can find out more here: https://www.apple.com/education/it/dep/.
If you still have the need to create an iTunes account for yourself or for your institution, the video below will guide you through this process. It’s really quite easy. Note – you have to be over 13 years of age to do this.
