How far behind are students, and did poorer districts lose more?
Core argument: The authors calculate that the average U.S. student was half a year behind in math and a third of a year behind in reading.
According to our calculations, the average student was half a year behind in math and a third of a year behind in reading. In 2019, the typical student in the poorest 10 percent of districts scored one and a half years behind the national average for his or her year – and almost four years behind students in the richest 10 percent of districts – in both math and reading. By 2022, the typical student in the poorest districts had lost three-quarters of a year in math, more than double the decline of students in the richest districts. The declines in reading scores were half as large as in math and were similarly much larger in poor districts than rich districts. The pandemic left students in low-income and predominantly minority communities even further behind their peers in richer, whiter districts than they were.
