Judge Ring is writing for The Examiner (8)
I believe the answer is:
assessor
'examiner' is the definition.
(I've seen this before)
'judge ring is writing' is the wordplay.
'judge' becomes 'assess' (to assess is to judge or rate).
'ring' becomes 'o' (letter resembling a ring).
'is writing' becomes 'r' (one of the traditional three R's of education).
'assess'+'o'+'r'='ASSESSOR'
'for the' is the link.
(Other definitions for assessor that I've seen before include "Valuer, estimator" , "Evaluator, estimator" , "One evaluates property" , "Examiner" , "One who rates for tax" .)
