The new Test of Expressive Language (TEXL) is a highly reliable and valid measure of a child's expressive spoken language ability. The test measures a child's ability to produce the following categories of English language forms:
The TEXL was co-normed with and is a companion to the Test for Auditory Comprehension of Language- Fourth Edition (TACL-4). Clinicians who have given both TACL-4 and TEXL to the same child can combine these scores to obtain a comprehensive measure of language ability across linguistic features (semantics, morphology, and syntax) as well as overall oral language ability using the reproducible TACL-4/TEXL Summary Form. This form is found in TACL-4 / TEXL Comprehensive Scoring Supplement. The TACL-4/TEXL Summary Form provides space to record TACL-4 and TEXL scores, calculate additional composite scores, conduct receptive-expressive discrepancy analyses, and profile these scores. These scores provide comprehensive information on oral language skills comparable to scores derived from the Test of Language Development- Primary, Fourth Edition (TOLD-P:4; Newcomer & Hammill, 2008), Test of Language Development- Intermediate, Fourth Edition (TOLD-I:4; Hammill & Newcomer, 2008), Oral and Written Language Scales, Second Edition (OWLS-II; Elizabeth Carrow-Woolfolk, 2011), Clinical Evaluation of Language Fundamentals, Fifth Edition (CELF-5; Semel, Wiig, & Secord, 2013), and the Comprehensive Assessment of Spoken Language (Carrow-Woolfolk, 2008).
Description of TEXL
Each item is composed of a word or sentence and a corresponding picture plate. The examiner reads the stimulus aloud and the subject is asked to answer a question, finish a sentence, or combine sentences based on the stimulus provided. The TEXL 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 or hard of hearing, articulation disorder, language impairment, Autism spectrum disorder, intellectual disorder as well as those who have been identified as gifted and talented.
TEXL coefficients alpha range between .93 and .95 for the subtests and is .97 for the Expressive Language Index. Average correlations with popular criterion measures of expressive language ability range from .72 to .86. Studies of diagnostic accuracy as it relates to sensitivity (median = .79), specificity (median =.91), classification accuracy (median = .86), and receiver operating characteristic/area under the curve (median = .95) are reported.
