What is the primary purpose of diagnostic tests in education?

The primary purpose of diagnostic tests in education is to help identify specific problem areas. These tests are designed to assess a student's understanding and skills in various subjects, allowing educators to pinpoint where a student may be struggling or excelling. By identifying these specifics, teachers can tailor their instruction to meet the individual needs of each student, providing targeted support or enrichment.

For instance, if a diagnostic test reveals that a student has difficulty with fractions, the teacher can focus on that area in upcoming lessons. This personalized approach to teaching is critical in addressing the varied learning needs present in a classroom. Unlike summative assessments, which evaluate overall mastery of content, diagnostic tests serve as a tool for enhancement of learning by providing actionable insights into students' knowledge gaps.
