An Introduction to Item Analysis - Number Everywhere!

As educators, we spend a lot of time thinking about and writing assessments - But how do we know whether or not we’ve done a good job thinking about and creating the assessment? Item analysis is a powerful tool that can tell us a lot about how that item, we’ll use item and question interchangeably, is functioning.
