I came across an article that I had saved on the NAEP (pronounced “nape”) test results over the last 12 years and Bill Gates pronouncement that our school system is a failure based on his perception that students have not shown any academic gains over the last 40 years.

Au contraire Mr. Gates, not according to the NAEP test.

Mr. Richard Rothstein with the Economic Policy Institute states in a report last year titled Fact Challenged Policy:

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.

We can see that in 4th grade math, black students now have higher average achievement than white students had when the assessments began. Average black students’ gains have been a full standard deviation, a rate of progress that would be considered extraordinary in any area of social policy. The black-white score gap has narrowed some, but not very much, because white students have also shown improvement.

Bill Gates may think that these improvements are insufficient, and perhaps he is correct. But, as Daniel Patrick Moynihan reportedly quipped, “everyone is entitled to their own opinions, but not to their own facts.” No rational reading of these NAEP data can support Bill Gates’ claim that “student achievement has remained virtually flat” over the last four decades.[†] And, to repeat, no other longitudinal data are available that describe student achievement over time.

These facts also don’t support the story that the typical teacher of disadvantaged children is ineffective. Certainly, some teachers are ineffective, and schools should do a better job of removing them. But that should not, if facts are to be believed, be the main story.

Yet it seems to be. Secretary of Education Arne Duncan recently asserted that “many, if not most, teacher-training programs are mediocre.” This may be true, but how does he know? What is his evidence? It wouldn’t seem that mediocre teacher training programs could consistently be turning out teachers who have posted the kinds of gains we’ve seen on NAEP in the last generation and more.

Mr. Rothchild continues:

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%.[‡]

Detailed tables documenting these trends are available here.

American public education can boast of remarkable accomplishments in special education over this period. Many young people can now function in society whereas, in the past, children with similar disabilities were institutionalized and discarded.
