What is the primary function of diagnostic assessments?

The primary function of diagnostic assessments is to determine prior knowledge and skill levels. These assessments are specifically designed to identify what learners already know and what skills they have before beginning instruction or a new learning unit. By understanding a student's baseline knowledge, educators can tailor their instruction to better meet the needs of their students, ensuring that gaps in understanding are addressed and that teaching strategies are appropriately aligned with learner capabilities.

This formative approach is critical because it helps identify areas where students may need additional support or intervention early on. Such insights can guide lesson planning, resource selection, and overall instructional strategies, leading to more effective learning experiences. Diagnostic assessments inform educators about student readiness and help guide future instruction, making them fundamental in educational settings.
