Following examination, boy's shown up in disgrace (7)
I believe the answer is:
scandal
'disgrace' is the definition.
(scandal can mean disgraceful behaviour or news)
'following examination boy's shown up' is the wordplay.
'following' says to put letters next to each other.
'examination' becomes 'scan' (scan is a kind of examination).
'boy' becomes 'lad' (informal term for boy).
'shown up' is a reversal indicator (in a down clue, letters go up).
'lad' in reverse letter order is 'dal'.
'scan' next to 'dal' is 'SCANDAL'.
'in' acts as a link.
(Other definitions for scandal that I've seen before include "Shocking thing" , "Dishonour" , "subject for play school" , "dirt" , "Subject of Sheridan's school" .)
