Assessment & Measurement – Diagnostic

Diagnostic assessments capture students’ prior knowledge and misconceptions on a given topic in order to pinpoint their individual strengths and areas needing improvement before the course, unit, or learning activity begins. Also known as a “pre-assessment,” they can provide instructors with the information they can use to adjust the course or learning activity according to students’ prior knowledge. This type of assessment can also help instructors identify what content needs to be taught, mastered, or discussed within the course.
