Measure, say, Reading University business degree (5)
I believe the answer is:
rumba
'measure' is the definition.
(rumba is a type of dance)
'say reading university business degree' is the wordplay.
'say reading' becomes 'r' (one of the traditional three R's of education).
'university' becomes 'u'.
'business' becomes 'm' (I've seen this in other clues).
'degree' becomes 'ba' (Bachelor of Arts).
'r'+'u'+'m'+'ba'='RUMBA'
(Other definitions for rumba that I've seen before include "Lively Cuban dance" , "Caribbean dance" , "music one can dance to" , "Cuban folk-dance" , "Burma (anag)" .)
