Goes on the stage (6)

I believe the answer is:

boards

I believe this is a double definition.

'goes on' is the first definition.
(I've seen this before)

'the stage' is the second definition.
(an actor 'treads the boards')

(Other definitions for boards that I've seen before include "Theatre stages" , "panels" , "Puts up" , "Actors are said to tread them" , "Long flat pieces of wood" .)

I've seen this clue in The Telegraph and The Guardian.
