The sex-crazed Brooklyn school that’s shed a number of teachers for grossly inappropriate behavior has lost another one, The Post has learned.

Former James Madison HS gym teacher Lisa Gutilla, 40, was fired this summer after a city probe found she had kissed and groped a 14-year-old girl at a private school in late 2009.

Sex-abuse charges brought against Gutilla in 2010 were dropped in 2011.
