HARRISBURG, Pa. (AP) — As some children struggled to keep up with school in the early years of the COVID-19 pandemic, many states saw significant increases in the number of students held back to repeat grades. Twenty-four of the 28 states that provided data for the most recent academic year saw increases, according to an Associated Press analysis. Three states — South Carolina, West Virginia and Delaware — saw retention more than double. Experts have cautioned about risks to students’ social lives and academic futures, but many parents have asked for do-overs to help their children recover.
