Marks as correct (5)

Ross

I believe the answer is:

ticks

'marks as correct' is the definition.
(I've seen this before)

This is the entire clue.

(Other definitions for ticks that I've seen before include "Bloodsuckers; seconds" , "Parasitic mites" , "Small arachnids" , "Mites in mattress" , "Signs of approval" .)

I've seen this clue in The Times, the Sydney Morning Herald and The Sunday Times.
