Instructional Quality Assessment (IQA)

The Instructional Quality Assessment (IQA) is a classroom observation instrument that rates the nature and quality of classroom instruction by considering students’ opportunities to engage in cognitively demanding mathematical work and discussions. The IQA uses the following elements to assess instruction: potential of the task, task implementation, rigor of the discussion, teacher’s questions, and accountable talk.
