In my June 25 blog post, I reported that effective Florida teacher preparation programs received no better ratings by the National Council on Teacher Quality (NCTQ) than ineffective ones.

The National Council on Teacher Quality, in conjunction with U. S. News and World Report, has issued an ambitious report evaluating the quality of teacher preparation programs in schools of education across the United States. But its critics argue that the report fails to show that its measure of program quality is correlated with the classroom effectiveness of a school’s graduates. If the information available to us for a few teacher preparation schools in Florida is at all representative, the critics may have a point.

Last summer, we released the first experimental study of the effect of school vouchers on college enrollment. Our study, which is published in the current edition of Education Next, generated significant controversy.

If correct, a barn burner of a study has just been released by the once self-proclaimed Marxist, Martin Carnoy, and his good friend Richard Rothstein. If you take into account the extraordinary size of the proletariat in the United States, and the miniscule size of its bourgeois, U. S. students are doing almost as well in math and reading as students in other industrialized countries. Even the Koreans don’t do much better, they say.

Success Academy is a big-time success story, as Charles Sahm makes clear (“What Explains Success at Success Academy?” features, Summer 2015). But what are the general lessons to be learned from the many case studies of successful chartering? Does it take the exceptional leadership of Success Academies’ Eva Moskowitz? Are school uniforms and a “no excuses” ethos the decisive ingredients (KIPP schools)? Are longer school days and an extended school year critical? Is data-based instruction the solution (Achievement First)? How important is a demanding academic curriculum (BASIS schools)?

In an important new report, America Achieves tells us that middle-class students in the United States are trailing their peers abroad. U.S. students were significantly outperformed by peers in 24 countries in math, if one looks only at those who fall just above the median position on its index of social and educational “advantage.” Among those who fall just below the index median, U.S. students ranked 32nd.

Over the past two decades, gains of 1.6 percent of a standard deviation have been garnered annually by 4th- and 8th-grade students on the math, science, and reading tests administered by the National Assessment of Educational Progress (NAEP), known as the nation’s report card. An upward trajectory of 1.6 standard deviations cumulates over 20 years to 32 percent of a standard deviation, well over a year’s worth of learning.

We know a good teacher can increase the lifetime income of a classroom by over $250,000,” the president told the country in his State of the Union speech. His comment was based on a pioneering study by Chetty, Friedman, and Rockoff, published in this issue (see “Great Teaching,” Research), which for the first time combines tax data that reveal earnings at age 28 with information on student learning when that
person was in elementary school.
