A carefully targeted measure of auditory perception, unconfounded by reasoning.

• Ages: 6-0 through 18-11
• Testing Time: 30 minutes

The DTAP is a battery of 5 item sets that measure different, but interrelated, aspects of auditory perception. It assess auditory perception without invoking higher order verbal reasoning or extensive memory capacity. It can be administered by psychologists, speech-language pathologists, general and special educators, neuropsychologists, and diagnosticians 

Items are presented from a CD, to standardize presentation of the language item sets, and to include non-language sounds. The DTAP uses a simple response format easily understood even by children in the primary grades. Using various language-related as well as non-language-related sounds, pairs of stimuli are presented, and examinees indicate whether the pairs are the same or different.

Five item sets

• Phonemes in Isolation
• Word Discrimination
• Rhyming Sounds
• Tonal Patterns
• Environmental Sounds

The item sets are divided into two auditory scales:

• Language Auditory Perception Index (LAPI)
• Nonlanguage Auditory Perception Index (NAPI)

The LAPI and the NAPI are combined to form the Composite Auditory Perception Index (CAPI), which is the best measure of auditory perception.

The DTAP Kit includes the Administration Audio CD, 25 each of the Student and Examiner Record Forms, and the Manual
