though all public schools are required to follow either the regents exam system or some form of alternative assessment, private schools need not. the vast majority of private schools do use regents exams and award regents diplomas, but some, usually academically prestigious private schools, do not. these schools' argument is that their own diploma requirements exceed regents standards. schools run by the society of jesus, such as canisius high school, fordham prep, mcquaid jesuit, regis and xavier, and by the society of mary (marianists), such as chaminade and kellenberg, have not used regents exams for decades. the masters school, the ursuline school, the hackley school, the harvey school, long island lutheran middle & high school, manlius pebble hill school, and nichols school also do not use the regents system.
