In what case did SCOTUS hold that a student may be searched at school, based on reasonable suspicion rather than probable cause (due to the school's need to maintain a healthy learning environment)?

i really hope i am right

Explanation: In the landmark case of New Jersey v. T.L.O. (1985) 469 U.S. 325, 341-42, the Supreme Court ruled than neither a warrant or probable cause is required for an on-campus search of a student or her personal property by a school official; reasonable suspicion is sufficient.
