You do not graduate from an unaccredited school. The way it works is that the school does not get full accreditation until the FIRST GRADUATING CLASS, at which time the school then becomes fully accredited. That is the "promise" to the first 4 classes that come in and historically, no school that has reached the accrediation level to admit its first class has ever failed to reach final accrediation. not something you need to be concerned about (though maybe evaluating how prepared you will be to pass a board exam based on the school's board pass history rate will be difficult when no such history exists)
