If Ram is not able to understand certain concept in a particular subject and 1s continuously performing poorly in that subject. which evaluation test will have to be conducted to know the cause of his difficulties?

Correct option is B

Diagnostic Evaluation
If Ram is consistently struggling to grasp certain concepts in a particular subject and is performing poorly, a diagnostic evaluation is the appropriate test to identify the root cause of his difficulties. Unlike placement evaluation, which determines initial skill levels for appropriate class placement, or summative evaluation, which assesses overall learning at the end of a course, a diagnostic evaluation delves deep into the specific areas of weakness. It helps educators pinpoint precisely which concepts or skills Ram is struggling with, allowing them to tailor their support and interventions accordingly. This targeted approach is crucial for addressing his difficulties effectively and facilitating his learning progress.
