The CAS2 comprises the following:

Administration and Scoring Manual. This manual provides general information, specific instructions for administering and scoring the subtests, norms tables, and interpretive tables.

Interpretive and Technical Manual. This manual presents the information needed to use the test, including a discussion of PASS theory and explanations of the test’s organization and development, as well as information on standardization, norming, reliability, validity, and interpretation of the CAS2.

Stimulus Books 1, 2, and 3. The Stimulus Books include all the subtest stimuli used during administration of the test. They provide the stimulus items for the Matrices, Verbal-Spatial Relations, Figure Memory, and Expressive Attention subtests.

Student Response Booklet. The CAS2 includes two age-based Student Response Booklets, one for ages 5 through 7 and one for ages 8 through 18. The booklets are intended for paper-and-pencil responses for the Planned Number Matching, Planned Codes, Planned Connections, Number Detection, and Receptive Attention subtests.

Figure Memory Response Book. This response book is intended for the paper-and-pencil responses to the Figure Memory subtest.

Scoring Templates. A spiral-bound booklet with scoring templates offers examiners a convenient aid for ease and accuracy in scoring Response Book pages.

Examiner Record Form. This provides space for recording responses for each subtest, as well as a summary of the scoring and permanent documentation of test results.

Red pencil. A red pencil, for use in subtests requiring written responses, is included in each CAS2 complete test kit.

NEW! Optional Spanish Supplements Package. An optional add-on package includes (a) a three-hole-punched Spanish translation of Chapters 1 through 3 of the Administration and Scoring Manual for insertion into the English three-ring binder, (b) a Spanish Expressive Attention and Verbal-Spatial Relations Stimulus Book, and (c) a pack of 10 Spanish CAS2 Examiner Record Forms.

Extensive reliability and validity information is reported in the Interpretive and Technical Manual that accompanies the test. The 12-subtest Core Battery Full Scale reliability is .95 with the PASS Scale reliabilities ranging from .86 to .93. Internal consistency, test-retest, and scorer reliability studies were conducted. Types of validity reported include content description, criterion prediction, and construct identification. Validity with special populations, including persons with speech or language impairments, Learning Disabilities, gifted and talented designations, Attention Deficit/Hyperactivity Disorder, Anxiety Disorder, or Asperger’s Syndrome, is reported. Special attention was paid to making the CAS2 fair for minority groups. Validity evidence reported in the Interpretive and Technical Manual demonstrates the test’s value for assessment of diverse groups of children and adolescents.

The CAS2 was standardized using a group of 1,342 children and adolescents, closely representative of the population of the U.S. based on census data. The 12-subtest Core Battery Full Scale reliability is .95 with the PASS Scale reliabilities ranging from .86 to .93.
