Test for Auditory Comprehension of Language 4th edition (TACL-4)
Assess receptive spoken language with Elizabeth Carrow-Woolfolk's time honored standard!
Ages: 3-0 through 12-11
Testing Time: 20 to 30 minutes
The Test for Auditory Comprehension of Language–Fourth Edition (TACL-4) is the latest revision of this popular, individually-administered test. It is a reliable and valid measure of a child’s receptive spoken vocabulary, grammar, and syntax. The test measures children’s ability to understand three language forms:
The TACL-4 was co-normed with and is a companion to the Test of Expressive Language (TEXL; Carrow-Woolfolk & Allen, 2014). While the TACL-4 measures a child’s receptive language ability the TEXL measures a child’s expressive language ability. 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.

Description of TACL-4
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.
The TACL-4 test items are ordered according to difficulty within each of the three subtests. Entry points, basal and ceiling rules for scoring are provided for each subtest. The Examiner’s Manual includes a comprehensive discussion of the test's theoretical and research-based foundation, item development, standardization, administration and scoring procedures, norms tables, and guidelines for using and interpreting the test’s results. 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 disorder 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.
Complete TACL-4 Kit includes: Examiner’s Manual, Picture Book, and 25 Examiner Record Booklets, all in a sturdy storage box. (©2014)
