Last week, Microsoft Chairman Bill Gates published an op-ed in the Washington Post, “How Teacher Development could Revolutionize our Schools,” proposing that American public schools should do a better job of evaluating the effectiveness of teachers, a goal with which none can disagree. But his specific prescriptions, and the urgency he attaches to them, are based on the misrepresentation of one fact, the misinterpretation of another and the demagogic presentation of a third. It is remarkable that someone associated with technology and progress should have such a careless disregard for accuracy when it comes to the education policy in which he is now so deeply involved.
Gates’ most important factual claim is that “over the past four decades, the per-student cost of running our K-12 schools has more than doubled, while our student achievement has remained virtually flat.” And, he adds, “spending has climbed, but our percentage of college graduates has dropped compared
with other countries.” Let’s examine these factual claims:
Bill Gates says: “Our student achievement has remained virtually flat”The only longitudinal measure of student achievement that is available to Bill Gates or anyone else is the National Assessment of Educational Progress (NAEP). NAEP provides trends for 4th, 8th, and 12th graders, disaggregated by race, ethnicity, and poverty, since about 1980 in basic skills in math and reading (called the “Long Term Trend NAEP”) and since about 1990 for 4th and 8th graders in slightly more sophisticated math and reading skills (called the “Main NAEP”).<*>
On these exams, American students have improved substantially, in some cases phenomenally. In general, the improvements have been greatest for African-American students, and among these, for the most disadvantaged. The improvements have been greatest for both black and white 4th and 8th graders in math. Improvements have been less great but still substantial for black 4th and 8th graders in reading and for black 12th graders in both math and reading. Improvements have been modest for whites in 12th grade math and at all three grade levels in reading.
The following table summarizes these results, for the earliest and most recent years for which disaggregated data were collected.

Bill Gates says: “The per-student cost of running our K-12 schools has more than doubled.”Here, Bill Gates is nominally correct, but misleading. When properly adjusted for inflation, K-12 per pupil spending has about doubled over the last four decades, but less than half of this new money has gone to regular education (including compensatory education for disadvantaged children, programs for English-language learners, integration programs like magnet schools, and special schools for dropout recovery and prevention). The biggest single recipient of new money has been special education for children with disabilities. Four decades ago, special education consumed less than 4% of all K-12 spending. It now consumes 21%.<‡>

Many young people can now function in society whereas, in the past, children with similar disabilities were institutionalized and discarded. But it is not reasonable to complain about the increase in spending on such children by insisting that it should have produced greater improvement in the achievement of regular children.

Bill Gates says: “Spending has climbed, but our percentage of college graduates has dropped compared with other countries.”This is the Bill Gates claim that can properly be called demagogic. It attempts to agitate readers by presenting a positive development in a negative light. A climb in spending should produce an increase in the percentage of college graduates. And it has. In the last four decades, the percentage of college graduates in the United States has nearly doubled. In 1970, 16% of young adults (ages 25 to 29) were college graduates. Today, it is 31%. The improvement has been across the board: the share of African-American young adults who are college graduates has gone from 10% to 19%; for whites it has gone from 17% to 37%. Somehow, Bill Gates saw fit to present this as an indictment.
