Dr. Jack A. Naglieri has created research-based assessments that offer fair and accurate measures of student ability. These tools help psychologists and educators make informed decisions and support every learner.
Authors: Jack A. Naglieri, Ph.D., Dina M. Brulles, Ph.D., and Kimberly Lansdowne, Ph.D.
The Naglieri General Ability Tests (NGAT) are three newly developed measures designed to identify gifted students fairly. Together, the Verbal (Naglieri & Brulles), Nonverbal (Naglieri), and Quantitative (Naglieri & Lansdowne) tests assess general ability using different content while reducing cultural and linguistic bias.
Naglieri Verbal (NV) measures general ability through picture-based items that require students to recognize and apply verbal concepts.
Naglieri Nonverbal (NN) measures general ability using matrix-based items that require analysis of shapes, sequences, and spatial relationships.
Naglieri Quantitative (NQ) measures general ability by examining numerical and symbolic relationships through basic math concepts.
All items were designed to minimize cultural influence, reduce the need for formal knowledge, and allow students to demonstrate reasoning skills regardless of the language they speak. The tests measure how well students think, not what they know.
Initial research (N = 8,410, grades K–12) shows minimal differences across gender, race/ethnicity, and parental education level, supporting the fairness and accuracy of these measures.

Designed to measure cognitive processing abilities that are important for a broad range of differential diagnoses and instructional planning, the Cognitive Assessment System, Second Edition (CAS2) is a norm-referenced measure based on the well-researched cognitive/neuropsychological theory called PASS (Planning, Attention, Simultaneous, and Successive). It provides practitioners with a valid and reliable tool to evaluate the strengths and weaknesses of children and adolescents in important areas of cognitive processing
Learn more about how the CAS-2 measures cognitive processes using the PASS theory framework.

The Cognitive Assessment System-Second Edition (CAS2) is a well-researched cognitive/neuropsychological theory called PASS (Planning, Attention, Simultaneous, and Successive). The CAS2 was designed to measure cognitive processing abilities important for broad range of differential diagnoses and instructional planning in individuals ages 5-0 through 18-11. CAS2 provides practitioners with a valid and reliable tool to evaluate children's strengths and weaknesses in important areas of cognitive processing.
The publisher of the CAS2 suite of measures of PASS theory provides virtual materials and watermarked copies of record forms for university training classes through our third party vendor, RedShelf. The materials are made available to the professors and students for the duration of the class. If interested please contact Terri Cooter using this email testquestion@proedinc.com to get set up.
The CAS2: Brief is a norm-referenced measure of cognitive ability based on the well-researched cognitive/neuropsychological theory called PASS (Planning, Attention, Simultaneous, and Successive). PASS abilities are evaluate using four subtests (Planned Codes, Simultaneous Matrices, Expressive Attention, and Successive Digits) which are combined to yield a Total Score. Each subtest yields a scaled score based on a mean of 10 and a standard deviation of 3. The sum of scaled scores can be converted a percentile rank and index score with a mean of 100 and a standard deviation of 15.
The CAS2: Rating Scale is a norm-referenced measure of behaviors related to cognitive/neuropsychological theory called PASS (Planning, Attention, Simultaneous, and Successive) completed by teachers. The rating scale provides scores for Planning, Attention, Simultaneous, and Successive scales as well as Total Score. Each PASS Scale as well as the CAS2 Full Scale yields a percentile rant and standard score with a mean of 100 and a standard deviation of 15.
The PC, Mac™, and iPad™ compatible CAS2 Online Scoring and Report System program is an efficient and easy way to obtain CAS2 scores and corresponding narrative.
