On the spot in further education (5)
I believe the answer is:
there
'on the spot' is the definition.
(I've seen this before)
'in further education' is the wordplay.
'in' indicates a hidden word.
'THERE' is hidden in the letters of 'further education'.
(Other definitions for there that I've seen before include "It's said to comfort" , "Exclamation of triumph or sympathy" , "Place: as indicated" , "Yonder" , "In position" .)
