Look over a report (6)
I believe the answer is:
survey
'look over' is the definition.
(surveying is a kind of looking over)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for survey that I've seen before include "Overview" , "Look thoroughly at" , "Critical inspection or descriptive summary" , "General examination" , "Scan or inspect" .)
