Concept:Diagnostic tests are designed to identify learning gaps and weaknesses in students so that teachers can plan specific remedial actions.
Explanation:Diagnostic tests are given after a course or unit to pinpoint persistent errors and learning difficulties.
They go beyond formative tests by finding the root causes of students' problems.
The main goal is to understand where each student is struggling and why.
This information helps the teacher to adjust the curriculum and provide targeted help.

Therefore, the purpose is to find out what students lack so that remedies can be planned effectively.
