Skill gets credit at the back (5)
I believe the answer is:
craft
'skill' is the definition.
(I know that craft is a type of skill)
'credit at the back' is the wordplay.
'credit' becomes 'cr' (abbreviation).
'at the back' becomes 'aft' (aft means towards or at the end of a ship).
'cr'+'aft'='CRAFT'
'gets' is the link.
(Other definitions for craft that I've seen before include "Skill, cunning" , "practical skill" , "Skill in making things by hand" , "boats" , "Cunning; boat, ship" .)
