What is diagnostic assessment?
Diagnostic assessment identifies prior knowledge, strengths and learning needs before instruction.
Core approach and practice
Conceptual framework Brief questions, concept maps, interviews or sample tasks may be used. The purpose is to reveal starting points and misconceptions rather than assign a grade. Implementation steps Each item should relate to upcoming objectives. Teachers plan review, support or extension from the results and examine error patterns, not just total scores.
Evaluation and practical cautions
Contribution to learning Diagnostics can prevent unnecessary repetition and help instruction begin at a suitable level. Learners should know the information guides support. Limits and sound use A diagnostic result is not a permanent ability label. Anxiety, language and instructions can affect performance, so major decisions should not rely on one measure.
