Diane Ravitch is the person who thinks a high school diploma is credible even if the possessor of the diploma doesn't know beginning algebra. Her argument is that she, a professor of history, was not required to know algebra in her generation (I would hope she at least took a course in the subject as part of secondary education), so it's asking too much that young people in the United States ought to be able to pass test that includes algebra item content as part of graduating from high school. Having seen countries that do otherwise in secondary education from how the United States does things, I have to respectfully disagree with Ravitch on that point and on many other points.
