Quote Of The Day

“After adjusting for multiple sources of bias and differences in sample construction, we establish that (1) the U.S. high school graduation rate peaked at around 80 percent in the late 1960s and then declined by 4-5 percentage points; (2) the actual high school graduation rate is substantially lower than the 88 percent estimate of the status completion rate issued by the NCIS [National Center for Educational Statistics]; (3) about 65 percent of blacks and Hispanics leave school with a high school diploma, and minority graduation rates are still substantially below the rates for non-Hispanic whites. In fact, we find no evidence of convergence in minority-majority graduation rates over the past 35 years….A significant portion of the convergence reported in the official statistics is due to black males obtaining GED credentials in prison.” — James J. Heckman and Paul A. LaFontaine, via Greg Mankiw
