Communication channels raising target to incorporate education (5)
I believe the answer is:
media
'communication channels' is the definition.
(I've seen this before)
'raising target to incorporate education' is the wordplay.
'raising' says the letters should be written backwards.
'target' becomes 'aim' ('aim' can be a synonym of 'target').
'to incorporate' means one lot of letters goes inside another.
'education' becomes 'ed' (abbreviation - e.g. sex ed).
'aim' reversed gives 'mia'.
'mia' going around 'ed' is 'MEDIA'.
(Other definitions for media that I've seen before include "Old Asian region" , "the box etc" , "oil and water, maybe" , "region near Caspian Sea" , "journalists' outlets" .)
