The CNNS is designed to assist clinicians and researchers in their interpretation of the tests included in its normative system. The Professional Manual provides age-based norms only, whereas the CNNS-SP provides norms based on eight different combinations of demographic and premorbid variables.

Features and benefits

• Raw scores are used to generate scaled scores, T scores, and percentiles for 73 measure and factor scores derived from 24 tests.
• Six summary or factor scores were constructed (Processing Speed, Attention/Working Memory, Verbal Learning and Memory, Visual Learning and Memory, Ideational Fluency, and Executive Functioning) from various measures within the tests.
• Twenty-two discrepancy scores are provided, along with significance tests and cumulative frequency analyses for the obtained differences to assess the examinee’s unique and relative strengths and weaknesses.
• A conormed approach provides you with greater confidence that differences in performance across cognitive domains reflect true cognitive strengths and weaknesses of your client.

Software provides essential information

• This unlimited-use software helps you easily convert scores for the tests normed by the CNNS. Although the Professional Manual provides age-based norms, the CNNS-SP takes it to the next level by providing norms based on eight different combinations of demographic variables and premorbid IQ.
• After you provide the client’s demographic and raw score information, the program automatically computes the selected demographically calibrated T scores and factor scores; it also classifies each score qualitatively (e.g., average, borderline, mildly abnormal).
