What is a Diagnostic Assessment?

A diagnostic test in education is a sort of pre-evaluation that enables the instructor to learn the extent of the student's subject-matter knowledge. In other words, it is used to determine the extent of a student's knowledge and to identify any potential learning gaps. They occur at the start of a learning experience, such as the start of a unit, lesson quarter, or time period.

Diagnostic assessments are also considered “low-stake” as they are not graded and do not help in deciding if the student should move on to the next class. However, these assessments are helpful in knowing the strengths and weaknesses of the student regarding a specific field of study.

How does a diagnostic assessment work? For example, you have started a new mathematics topic on quadratic equations. In that case, you can conduct a simple test to understand how much information is already known to the student about that particular topic.

What are the Features of a Diagnostic Test in Education?

To call an assessment a “diagnostic test”, it must meet the following criteria:

  • A diagnostic evaluation is required to take place at the start of the new semester or lesson unit.

Informal Diagnostic assessments are employed when you swiftly need to measure students’ knowledge about the subject or topic. It is fast and brief in nature.

Examples of Diagnostic Assessments

  • Surveys and Questionnaires
  • Unit Pretest - Fill in the gap questions
  • Checklists
  • Curriculum-based Measurement
  • Impromptu Quiz - spontaneous quiz

Knowing a student's current level of knowledge allows you to adjust your teaching strategy to best meet their immediate needs. Let's examine some additional benefits of using diagnostic tests in the classroom.
