I believe you are misunderstanding the design and intent of the CPI. The CPI is intended to identify the significance of DIFFERENCES between and among processing areas for the individual being rated, NOT how low or high any specific score may be. A true learning disability involves significant discrepancies, not only between ability and achievement, but more importantly between different areas of information processing (which are really the basis of the learning disability). When a parent or teacher rates significant concerns across all processing areas, no 'specific' processing concerns can be identified on the CPI. This may suggest that the student has global processing issues which may be related to general cognitive delays or factors other than a learning disability. This also sometimes occurs when the person completing the rating is simply overly critical and fails to accurately identify areas of strength as well as weakness. If you have further questions or concerns, please contact me directly via email. Thanks.
