Crossword Genius

Understood to make the grade (8)

Ross

I believe the answer is:

'understood' is the definition.
('gather' can be a synonym of 'understand')

'make the grade' is the wordplay.
'make' is an anagram indicator.
'the'+'grade'='thegrade'
'thegrade' is an anagram of 'GATHERED'.

'to' is the link.

(Other definitions for gathered that I've seen before include "Surmised", "Concluded from evidence", "Gleaned", "Collected - inferred", "Understood".)

I've seen this clue in Evening Standard.
