How bad was pandemic learning loss? We have an idea now

Kids in the US have had a couple of rough years at school because of the COVID-19 pandemic. One academic year was turned upside down as everyone scrambled to online learning on the fly. The next year was better, but you still had kids in and out of the classroom and there wasn't always consistency. And throughout it all, there has been a lot of concern for how much learning for kids was interrupted, and the impact that has. So is this something we can measure? The not-for-profit organization NWEA supports students and educators, and they've done some research into how far kids fell behind and if we are seeing them bounce back. We wanted to talk about this research, what it says and what it means so we caught up with Karyn Lewis, PhD, Director of the Center for School and Student Progress.
