[CM 0355]

Ages: 3 months through 3 years
Testing Time: 20 to 30 minutes
Administration: Individual

Cognitive Abilities Scale - Second Edition (CAS­-2) provides norm-referenced results useful in identifying children who have delays in cognitive development. A General Cognitive Quotient describes overall performance across all test items. A Nonvocal Cognitive Quotient describes children's ability excluding performance on vocal items. This quotient is used for infants, toddlers, and preschoolers who are shy, have unintelligible speech, or are unwilling or unable to vocalize or talk. Results from the CAS­2 provide detailed information for planning instructional programs. The CAS­2 is playful in nature, and the engaging toys enhance children's interest as well as the validity of the results. The CAS­2 is designed to ease administration and scoring for examiners and the kit is easy to transport. The inconsistent nature of infant and toddlers' responding is considered in the format of the test. Two forms are available in this revision: the Infant Form and the Preschool Form.

The Infant Form allows testing of children as young as 3 months. It consists of 79 items divided into 3 sections:

• Exploration of Objects
• Communication with Others
• Initiation and Imitation.

• Oral Language
• Reading
• Math
• Writing
