Check off for credit (4)

I believe the answer is:

tick

I believe this is a double definition.

'check off' is the first definition.
(thesaurus)

'credit' is the second definition.
(I've seen this in other clues)

'for' acts as a link.

(Other definitions for tick that I've seen before include "Parasite - mark of approval" , "Objectionable person" , "Mark correct, parasite" , "Make sound like old clock" , "Blood-sucking mite or parasitic insect" .)

I've seen this clue in the Evening Standard.
