Tinker has never been directly overruled, but in the subsequent years since then, the Court has narrowed its scope somewhat. See Bethel School District No. 403 v. Fraser, 478 US 675 (1986), and especially Hazelwood School District v. Kuhlmeier, 484 US 260 (1988).

"...Tinker has never been directly overruled..."

You are correct!!

The Tinker case stated, if memory serves, that "Students do NOT shed their RightS at the Schoolhouse Gate."
