Measures a child's expressive spoken language ability
TEXL - Test of Expressive Language Manual

Overview

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: Vocabulary, Grammatical Morphemes, and Elaborated Phrases and Sentences

  • 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
  • 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
  • Each item on the test was evaluated using both conventional item analyses to choose "good" items, and the new differential analyses to find and eliminate potentially biased items Reliability coefficients were computer for subgroups of the normative sample as well as for the entire normative group
  • A major effort has been made to demonstrate conclusively that the test is both reliable and valid, including diagnostic accuracy analyses, particularly rigorous techniques involving the computation of the sensitivity index, specificity index, the receiver operating characteristic/area under curve (ROC/AUC)
