Broadcasts school results (5)
I believe the answer is:
sends
'broadcasts' is the definition.
('send' can be a synonym of 'broadcast')
'school results' is the wordplay.
'school' becomes 's'.
'results' becomes 'ends'.
's'+'ends'='SENDS'
(Other definitions for sends that I've seen before include "Causes to go somewhere" , "Transmits" , "Despatches" .)
