Shock over Jack losing final point in rating (9)
I believe the answer is:
appraisal
'rating' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for appraisal that I've seen before include "rating" , "Evaluation - papal airs (anag)" , "judgement" , "Evaluation - price survey" , "Formal assessment of an employee's performance" .)
