Trashy equipment given to school (6)
I believe the answer is:
kitsch
'trashy' is the definition.
(I've seen this before)
'equipment given to school' is the wordplay.
'equipment' becomes 'kit' (kit is a kind of equipment).
'given to' means one lot of letters go next to another.
'school' becomes 'sch' (common abbreviation).
'kit'+'sch'='KITSCH'
(Other definitions for kitsch that I've seen before include "Articles of dubious taste" , "Garish and in bad taste" , "Tacky" , "in vulgar fashion" , "Pretentiousness and bad taste in art" .)
