TACL-4

Overview

Overview

The Test for Auditory Comprehension of Language-Fourth Edition (TACL-4) is a reliable and valid measure of a child's receptive spoken vocabulary, grammar, and syntax.

  • Measures children's ability to understand three language forms: Vocabulary, Grammatical Morphemes, and Elaborated Phrases and Sentences
  • All-new normative data were collected in 2012 and 2013 and were stratified by critical variables reported for the preschool and school-age population reported in the Statistical Abstract of the United States 2013 (ProQuest, LLC, 2012)
  • The age-range of the test was extended upward to include ages 10-0 through 12-11
  • Age-related entry points, basals, and ceilings ensure that testing time is kept to a minimum and children are only tested on the items that are optimal for their ability level
  • Floor effects and ceiling effects present in the subtests of the third edition were addressed by the addition of both easy and difficult items to the test
  • Each item on the test was re-evaluated using both conventional item analyses to choose "good" items, and the new differential analyses to find and eliminate potentially biased items
  • A major effort has been made to demonstrate conclusively that the fourth edition is both reliable and valid
  • A copy of the Critical Reviews and Research Findings for TACL: 1965-2013 is included with each test kit

Normative Data

Normative Data

Each item is composed of a word or sentence and a corresponding picture plate that has three full-color drawings. One of the three pictures for each item illustrates the meaning of the word, morpheme, or syntactic structure being tested. The other two pictures illustrate either two semantic or grammatical contrasts to the stimulus, or one contrast and one decoy. The examiner reads the stimulus aloud, and the subject is directed to point to the picture that he or she believes best represents the meaning of the word, phrase, or sentence spoken by the examiner. No oral response is required on the part of the subject.

Reliability and validity studies were conducted out with individuals with normal language abilities and individuals who had previously been diagnosed with learning disabilities, ADHD, deaf/hard of hearing, Articulation Disorder, Language Impairment, Autism Spectrum Disorder, Intellectual Disorders as well as those who have been identified as gifted and talented.

TACL-4 coefficients alpha range between .94 and .96 for the subtests and is .97 for the Receptive Language Index. Average correlations with popular criterion measures of receptive language ability range from .67 to .71. Studies of diagnostic accuracy as it relates to sensitivity (median = .77), specificity (median =.84), classification accuracy (median = .80), and receiver operating characteristic/area under the curve (median = .88) are reported.

The TACL-4 was co-normed with and is a companion to the Test of Expressive Language (TEXL; Carrow-Woolfolk & Allen, 2014). Because the tests are co-normed, TACL-4 results can be meaningfully compared to those of the TEXL. Norms for the TACL-4 are based on a nationally-representative sample of 1,142 children in the U.S. Percentile ranks, standard scores, and age equivalents are provided.
