Only 2.7% of U.S. K-12 students were enrolled in online-only schooling in 2020–21, yet districts still had to solve real access and learning issues as online instruction expanded. At the same time, the K-12 edtech market is projected to grow at a 23% CAGR through 2030 while 19% of households reported no computer access during COVID-era remote learning. The gap between adoption and access helps explain why outcomes, engagement, and teacher support varied so sharply.
