The TELD-4 is a highly reliable and valid measure of spoken language in children ages 3 years 0 months through 7 years 11 months. Like the previous edition, the test yields Receptive Language and Expressive Language subtest index scores, as well as a Spoken Language index score. All users now have access to the new optional PC-, Mac-, Chromebook, and tablet-compatible TELD-4 Online Scoring and Report System via activation codes that are included in each package of TELD-4 Examiner Record Booklets.
TELD-4’s psychometric qualities:
Demographics: The TELD-4 was standardized on a representative sample of 1,074 children representing 32 states and 292 different zip codes.
Reliability: Extensive studies of test reliability (coefficient alpha, test-retest, immediate and delayed alternate forms, and interscorer) support the use of the TELD-4 with individual students. Average coefficient alphas for the full normative sample range from .95 to .97 for subtests and the composite.
Validity: Content-description validity was established through careful selection of items, controlled vocabulary, construct review by a panel of language experts, conventional item analysis, as well as analysis of the test floors, ceilings, and item gradients, and differential item functioning. Criterion prediction validity was established by (a) correlating TELD-4 standard scores with commercially available measures of reading ability (i.e., PLS-5, TACL-4, and TEXL), (b) comparing means and standard deviations between the TELD-4 and criterion tests, and (c) computing sensitivity, specificity, and ROC/AUC statistic.
Construct-identification validity was established by studying (a) the relationship of the TELD-4
standardized scores with age, academic achievement, and intelligence; (b) the ability of the test’s standard scores to differentiate groups with known language problems from those without such problems; and (c) the factorial fit of the subtests to the construct in the test model (i.e., spoken language)
