An improvement (1,4,3,3,6)

Ross

I believe the answer is:

a turn for the better

'an improvement' is the definition.
(I have seen 'An improvement ' mean 'a turn for the better' so perhaps 'improvement' could also mean 'a turn for the better')

This is all the clue.

(Another definition for a turn for the better that I've seen is " An improvement".)

I've seen this clue in The Times.
