Schooled, trained (8)
I believe the answer is:
educated
This clue is a double definition.
'schooled' is the first definition.
('educate' can be a synonym of 'school')
'trained' is the second definition.
('educate' can be a synonym of 'train')
(Other definitions for educated that I've seen before include "Instructed, taught" , "Learned - cultivated" , "Well-read" , "Trained; learned" , "Clever" .)
