Somehow leave education following complaint ultimately that's raised (8)
I believe the answer is:
elevated
'raised' is the definition.
(similar in meaning)
'somehow leave education following complaint ultimately' is the wordplay.
'somehow' indicates anagramming the letters.
'education' becomes 'ed' (abbreviation - e.g. sex ed).
'following' is a charade indicator (letters next to each other).
'ultimately' says to take the final letters.
The last letter of 'complaint' is 't'.
'leave' with letters rearranged gives 'eleva'.
'ed' put after 't' is 'ted'.
'eleva'+'ted'='ELEVATED'
'that's' acts as a link.
(Other definitions for elevated that I've seen before include "by such an American railway?" , "Heightened" , "Raised (in status)" , "Raised up as to peerage" , "given lift" .)
