Schools across America are racing to make up for lost classroom time, budgeting billions of dollars for tutoring, summer camps and longer school days. But figuring out which students need help has become its own challenge after the pandemic left holes in some students' learning records. New York City is adding three rounds of testing this year, hoping to pinpoint which students are behind and where. Similar tests are being used in Virginia's Fairfax County, which is allotting larger shares of funding to schools with lower scores. (AP Photo/J. Scott Applewhite, File)
