President Biden's recent insistence that standardized testing should happen this year has been met with reluctance in many states. Harvard Professor Andrew Ho explains the importance of moving forward with standardized testing and what it can tell us about the impact of COVID on students. Ho is a psychometrician who studies educational assessments. He explains why we must consider this more an "educational census" rather than an "assessment" and how to achieve that. He also discusses how much we actually know about learning loss, and how testing may offer insight into targeting supports.
