The TAPS-4 provides information about language processing and comprehension skills across three intersecting areas: phonological processing, auditory memory, and listening comprehension.

Features and benefits

  • Updates include new and revised subtests, fully updated normative data, and an expanded age range to 21 years.
  • An audio CD features audio administration for the subtests for which proper pronunciation of speech sounds is critical, allowing for more consistent and reliable administration of the phonological subtests.
  • Scaled scores are provided for subtests; standard scores are provided for cores and the overall score. Discrepancy scores allow comparison of performance across subtests.

Test structure

  • Includes 11 subtests that are organized into three indexes.
  • Responses to stimuli are recorded with a unique microswitch providing millisecond timing accuracy and is compared to both the normative sample as well as a group of individuals diagnosed with ADHD.
  • The Phonological Processing Index includes Word (Pair) Discrimination, Phonological Deletion, Phonological Blending, and Syllabic Blending subtests.
  • The Auditory Memory Index includes Number Memory Forward, Word Memory, Sentence Memory, and Number Memory Reversed subtests.
  • The Listening Comprehension Index includes Processing Oral Directions, Auditory Comprehension, and Auditory Figure-Ground subtests.

Technical information

  • The normative sample (N = 2,023) included individuals with specific language impairment, learning disability, auditory processing disorder, ADHD, and hearing impairment.
  • Reliability studies indicate internal consistency coefficients were .80 to .89 for the index scores and .93 for the TAPS-4 Overall score.
  • Validity measures include confirmatory factor analysis and matched-pairs factor analysis.
