Cognitive Processing Inventory (CPI)


for the assessment of information processing skills,

evaluation of learning styles,


differential diagnosis of specific learning disabilities



Scott L. Crouse, Ph.D.


On this site you can learn about this new evaluation tool which has been developed to assist with the diagnosis and treatment of learning disabilities.

What is the CPI?

The CPI is a non-biased, standardized behavior rating scale which can be completed by parents, teachers and students to evaluate information processing characteristics as part of formal or informal learning style and/or learning disability assessment.

The CPI provides scores in the processing areas of:

• Auditory Processing

• Visual Processing

• Sequential/Rational Processing

• Conceptual/Holistic Processing

• Processing Speed

• Executive Functioning

Go here for information about these processing areas and how each relates to learning.


Here are some of the highlights of the CPI:

  • The CPI provides a meaningful evaluation of underlying information processing characteristics of individuals with and without learning disabilities.


  • The CPI can be used either as part of a formal assessment process or as a pre-referral 'screening' tool.


  • The CPI can be used as a 'learning style' assessment for all students and adults.


  • The CPI rating forms are now available in both English and Spanish. 


  • The CPI provides a convenient and reliable method of objectively rating the long-term knowledge that parents have about their own children's' learning or processing characteristics.


  • The processing model of the CPI is based upon the most compelling cognitive research related to neuropsychological development and education.


  • The CPI has been thoroughly tested and refined over the past 15 years with extensive data and factor analytic evaluation.


  • The CPI provides standardized scores which allow examiners to determine the statistical significance of any processing pattern which is found.


  • The CPI not only evaluates the underlying 'processing' cause of existing learning difficulties but is also able to predict future problem areas both within and outside of a school environment.


  • The CPI provides a 'practical' assessment of cognitive processing with clear and useful programming implications for educators.


  • The computer scoring program for the CPI is simple to use and provides multiple levels of interpretive guidance and support.


  • The CPI helps to identify 'risk factors' from a student's background which may point to the origin of their cognitive processing difficulties.


  • The CPI 'makes sense' to parents, educators, and students.


  • The on-line CPI provides parents educators, and individuals with a convenient and risk-free means of trying out this assessment tool.
