The latest issue of Hillsdale College’s Imprimis features Charles Murray‘s argument against the continued existence of the U.S. Department of Education. Murray offers three reasons for shuttering the department. First, it’s unconstitutional. Second, there are no problems in public education today that can be tackled only at the federal level.

If neither of those arguments convinces you, Murray asks you to examine the Education Department’s track record.

What about the education of the disadvantaged, especially minorities? After all, this was arguably the main reason that the federal government began to get involved in education—to reduce the achievement gap separating poor children and rich children, and especially the gap separating poor black children and the rest of the country.

The most famous part of the Elementary and Secondary Education Act was Title I, initially authorizing more than a billion dollars annually (equivalent to more than $7 billion today) to upgrade the schools attended by children from low-income families. The program has continued to grow ever since, disposing of about $19 billion in 2010 (No Child Left Behind has also been part of Title I).

Supporters of Title I confidently expected to see progress, and so formal evaluation of Title I was built into the legislation from the beginning. Over the years, the evaluations became progressively more ambitious and more methodologically sophisticated. But while the evaluations have improved, the story they tell has not changed. Despite being conducted by people who wished the program well, no evaluation of Title I from the 1970s onward has found credible evidence of a significant positive impact on student achievement. If one steps back from the formal evaluations and looks at the NAEP test score gap between high-poverty schools (the ones that qualify for Title I support) and low-poverty schools, the implications are worse. A study by the Department of Education published in 2001 revealed that the gap grew rather than diminished from 1986—the earliest year such comparisons have been made—through 1999.
