The National Center for Education Statistics, part of the U.S. Department of Education, has just released a study comparing the performance of fourth- and eighth-graders in public and private schools. As important as this research may sound, I think it is more a symptom of our education problems than a useful tool in solving them. Generally, studies show students in private schools outperforming students in public schools. However, in this research, statistical adjustment was made to account for differences in socioeconomic background. The result: Whereas the raw data shows superior performance in private schools, much of that differential is eradicated after the statistical massaging. Public-school fourth-graders did better; however, the reading advantage at the eighth-grade level remained with the private-school kids. ()() Just as I suspected. The government education monopoly manipulated the numbers ot make themselves look better.
