Attendance Works, a nonprofit that works to reduce chronic absence across the nation, said it will check the data and update the report. Fothergill said Attendance Works relied on school systems to deliver accurate information to the U. S. Department of Education’s Office of Civil Rights. Prince George’s County had not reported any chronic absences in a previous school year, so an increase in the state’s rate didn’t raise a red flag because data had been missing previously, Fothergill said.
