Concept inventory

A concept inventory is like a quiz. It is made up of questions about different concepts in the subject you are studying. For example, if you were studying math, the concept inventory might include questions about addition, subtraction, multiplication, and division. Answering these questions will tell your teacher how much you know about the subject. It will help them to know what to review with you and what topics to focus more on in the future.
