Appraises, assesses (6)
I believe the answer is:
values
I believe this is a double definition.
'appraises' is the first definition.
(valuing is a kind of appraising)
'assesses' is the second definition.
(valuing is a kind of assessing)
(Other definitions for values that I've seen before include "Principles or standards of behaviour" , "Prizes, holds in high esteem" , "Appraises, assesses" , "Considers to be of great worth or importance" , "Moral principles, standards" .)
