<p>I thought that Yale did not in fact require graduation from high school, so the whole question of GED vs. regular diploma would be moot. On the other hand, in many/most cases the circumstances that led one to acquire a GED rather than a regular diploma would not be moot. My guess is that a GED is hardly an absolute barrier, but that there had better be a strong, compelling story to tell. (This is all apart from the Eli Whitney program, where GEDs are probably common.)</p>
