This quick guide to classroom assessment techniques (CATs), all forms of formative assessment, defines what CATs are, explains why you should use them, and provides a selection of useful examples.

Classroom Assessment Techniques (CATs) are generally simple, non-graded, anonymous, in-class activities designed to give you and your students useful feedback on the teaching-learning process as it is happening.

Examples of CATs include the following.

  • The Background Knowledge Probe is a short, simple questionnaire given to students at the start of a course, or before the introduction of a new unit, lesson or topic. It is designed to uncover students’ pre-conceptions.
  • The Minute Paper tests how students are gaining knowledge, or not. The instructor ends class by asking students to write a brief response to the following questions: “What was the most important thing you learned during this class?” and “What important question remains unanswered?”
  • The Muddiest Point is one of the simplest CATs to help assess where students are having difficulties. The technique consists of asking students to jot down a quick response to one question: “What was the muddiest point in [the lecture, discussion, homework assignment, film, etc.]?” The term “muddiest” means “most unclear” or “most confusing.”
