An Education plan includes a free Workspace with 50 GB of storage and Editor seats (depending on your education status) with access to the Mac app for one year.
Academic Institutions are entitled to a Workspace with multiple seats – dependent on meeting certain criteria.
Students currently enrolled in studies and employed Teachers can receive a Workspace with 1 Editor seat, which allows access to the Mac app.
If you’re a Student or Teacher, you can use Sketch for free for as long as the use is part of your studies or the course you’re teaching. Similarly, if you represent an Academic Institution, you can freely offer Sketch to your students as part of your course(s).
