Antwon Gibson’s public high school in Northeast Washington didn’t even attempt to teach his “independent living” class virtually this spring. The gregarious 18-year-old has an intellectual disability and reads and performs math below grade level. He’s been out of the classroom since schools closed in March and now requires more help from his family to break down multi-syllabic words.

Ayo Heinegg’s son, a rising sixth-grader in the District with dyslexia and attention-deficit/hyperactivity disorder, is typically a high-performing student. But he struggled to keep up with his coursework on multiple online platforms and lost his confidence in the classroom.

And in Loudoun County, 8-year-old Theo Duran, who is autistic, struggles more to walk up the stairs or hold a crayon to write — all tasks he was making progress on before the coronavirus pandemic hit and shut down his school.

Parents across the country who have students with special education needs say the stakes are high if schools do not reopen soon. They say their children are not just falling behind academically but are missing developmental milestones and losing key skills necessary for an independent life.
