With the newly revised TAPS-3, two levels of this test are no longer needed. TAPS-3 measures auditory processing skills of children ages 4 through 18 years. Subtests are now sequenced in developmental order of tasks from easy to difficult. The content of some subtests has been revised and four new subtests have been added: Phonological Segmentation, Phonological Blending, Auditory Comprehension, and Auditory Reasoning (replaces Auditory Processing subtest from previous editions).

An optional Auditory Figure-Ground task on CD-ROM has been added as a supplemental subtest to flag attention problems and give feedback on auditory processing skills in "real-world" situations.

Individual subtest scores are combined to derive three Cluster Scores: Basic Auditory Skills (Word Discrimination, Phonological Segmentation, and Phonological Blending), Auditory Memory (Number Memory Forward, Number Memory Reversed, Word Memory, and Sentence Memory), and Auditory Cohesion (Auditory Comprehension and Auditory Reasoning).
