Third Edition
The Test for Auditory Comprehension of Language-Third Edition (TACL-3) is a popular, individually administered measure of receptive spoken vocabulary, grammar, and syntax. The test consists of 142 items divided into three subtests that assess a child's ability to understand the following categories of English language forms: Subtest 1 - Vocabulary: The literal and most common meanings of word classes such as nouns, verbs, adjectives, and adverbs, and of words that represent basic percepts and concepts. Subtest 2 - Grammatical Morphemes: The meaning of grammatical morphemes such as prepositions, noun number and case, verb number and tense, noun-verb agreement, derivational suffixes, and the meaning of pronouns, tested within the context of a simple sentence. Subtest 3 - Elaborated Phrases and Sentences: The understanding of syntactically based word relations and elaborated phrase and sentence constructions, including the modalities of single and combined constructions (interrogative sentences, negative sentences, active and passive voice, direct and indirect object), embedded sentences, and partially and completely conjoined sentences. The TACL-3 was normed on a standardization sample of 1,102 children. Percentile ranks, standard scores, and age equivalents are provided. New Features in the Third Edition
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-3 test items are ordered according to difficulty within each of the three subtests. Ceiling rules for scoring are provided for each section. 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 studies were carried out with individuals with normal language abilities and individuals who are language delayed, hearing impaired, aphasic, or mentally retarded. |
