Do high school students receive the education discount?

According to this, you need to be a college student:

(excerpt):

Education pricing is available to current and newly accepted college students and their parents, as well as faculty, staff, and homeschool teachers of all grade levels. For more information, visit apple.com/us-hed/shop.

Yes.

Thanks for the correction, @babowa!

No

No problem; Apple has changed some other terms in other documents (warranty, Applecare) recently, so I don't know if this was changed or always been for college or higher.
