Kentucky's Educational Progress Proclaimed in Yet Another Study

This from Education Next:
To find out whether the United States is narrowing the international education gap, we provide in this report estimates of learning gains over the period between 1995 and 2009 for 49 countries from most of the developed and some of the newly developing parts of the world. We also examine changes in student performance in 41 states within the United States, allowing us to compare these states with each other as well as with the 48 other countries...

Our findings come from assessments of performance in math, science, and reading of representative samples in particular political jurisdictions of students who at the time of testing were in 4th or 8th grade or were roughly ages 9‒10 or 14‒15. The political jurisdictions may be nations or states. The data come from one series of U.S. tests and three series of tests administered by international organizations. Using the equating method described in the methodology sidebar, it is possible to link states’ performance on the U.S. tests to countries’ performance on the international tests, because representative samples of U.S. students have taken all four series of tests...


In absolute terms, the performance of U.S. students in 4th and 8th grade on the NAEP in math, reading, and science improved noticeably between 1995 and 2009. Using information from all administrations of NAEP tests to students in all three subjects over this time period, we observe that student achievement in the United States is estimated to have increased by 1.6 percent of a standard deviation per year, on average. Over the 14 years, these gains equate to 22 percent of a standard deviation. When interpreted in years of schooling, these gains are notable. On most measures of student performance, student growth is typically about 1 full standard deviation on standardized tests between 4th and 8th grade, or about 25 percent of a standard deviation from one grade to the next. Taking that as the benchmark, we can say that the rate of gain over the 14 years has been just short of the equivalent of one additional year’s worth of learning among students in their middle years of schooling. Yet when compared to gains made by students in other countries, progress within the United States is middling, not stellar (see Figure 1 above)...

Which States Are the Big Gainers?

Progress was far from uniform across the United States. Indeed, the variation across states was about as large as the variation among the countries of the world. Maryland won the gold medal by having the steepest overall growth trend. Coming close behind, Florida won the silver medal and Delaware the bronze. The other seven states that rank among the top-10 improvers, all of which outpaced the United States as a whole, are Massachusetts, Louisiana, South Carolina, New Jersey, Kentucky, Arkansas, and Virginia. See Figure 2 for an ordering of the 41 states by rate of improvement....


Some regional concentration is evident within the United States. Five of the top-10 states were in the South, while no southern states were among the 18 with the slowest growth. The strong showing of the South may be related to energetic political efforts to enhance school quality in that region. During the 1990s, governors of several southern states—Tennessee, North Carolina, Florida, Texas, and Arkansas—provided much of the national leadership for the school accountability effort, as there was a widespread sentiment in the wake of the civil rights movement that steps had to be taken to equalize educational opportunity across racial groups. The results of our study suggest those efforts were at least partially successful.

Meanwhile, students in Wisconsin, Michigan, Minnesota, and Indiana were among those making the fewest average gains between 1992 and 2011. Once again, the larger political climate may have affected the progress on the ground...
