A school bulletin board posted before 2019 exams notes the limits of standardized testing. North Carolina recently got a federal waiver from some year-end testing requirements, but that doesn’t mean students can skip those exams. The federal waiver means North Carolina is not required to issue school letter grades, school report cards or low-performing school labels based on student test scores this year. But unlike last spring, when the exams themselves were canceled because of the pandemic, students will have to take state exams in May. And they’ll have to come to school to do that, even if they’ve been learning remotely all year. Accountability Director Tammy Howard told the state Board of Education on Wednesday it’s not practical to ensure testing security from students’ homes.
