ELI5: Explain Like I'm 5

Hanna curve

The Hanna Curve is a way to track student achievement over time. Every student's learning is tracked and compared to others in their grade. By doing this, teachers are able to see which students are doing well and which ones need some help to catch up. It helps teachers give better support to the students who need it most. It also can be used to measure progress towards educational goals, like reading levels or math scores.
