wait for an student to report that they may have a concussion

Explanation:

Concussions are often identified by observing signs and symptoms rather than just relying on scans (as scans may not always show clear evidence immediately) or waiting for self - report (as some individuals may not recognize or report symptoms). Signs and symptoms can include headache, dizziness, confusion, memory problems, etc., which can be noticed after a head or body hit.

Answer:

Watching for different types of signs or symptoms after a student gets a hit to the head or body.
