Court calendar shows one hoping to be accepted (9)

I believe the answer is:

triallist

'one hoping to be accepted' is the definition.
(an employee who is on trial)

'court calendar' is the wordplay.
'court' becomes 'trial' (trial court is a kind of court).
'calendar' becomes 'list' (calendar can mean a list of events).
'trial'+'list'='TRIALLIST'

'shows' is the link.

(Another definition for triallist that I've seen is " Competitor".)

I've seen this clue in The Guardian.
