Equipment given to school is trashy stuff (6)
I believe the answer is:
kitsch
'trashy stuff' is the definition.
(trashy or tasteless items)
'equipment given to school' is the wordplay.
'equipment' becomes 'kit' (kit is a kind of equipment).
'given to' says to put letters next to each other.
'school' becomes 'sch'.
'kit'+'sch'='KITSCH'
'is' acts as a link.
(Other definitions for kitsch that I've seen before include "Excessively garish or sentimental" , "Pretentiousness and bad taste in art" , "Trash, trashy" , "Vulgarly pretentious art" , "Vulgarised art" .)
