Boards in French schools (8)

Ross

I believe the answer is:

entrains

'boards' is the definition.
(entraining is a kind of boarding)

'in french schools' is the wordplay.
'in french' becomes 'en' (French word for 'in').
'schools' becomes 'trains' (training is a kind of schooling).
'en'+'trains'='ENTRAINS'
