description
Description

    • Vocabulary
    • Grammatical morphemes
    • Elaborated Phrase
  • Each item consist of three color drawings
    • One picture illustrates the meaning of the word or phrase being tested
    • The other two pictures illustrate a semantic or grammatical contrast to the stimulus
    • Or in some cases, one picture illustrates a contrast to the stimulus and the other is a decoy
standardization
Standardization
  • Norms based on 1102 normal developing children , ages 3.0 to 9.11, from 24 states.
  • When standardizing this test the following were considered:
    • Geographic area
    • Age
    • Gender
    • Race
    • Ethnicity
    • Disability status
    • Education of Parents
reliability
Reliability
  • Validity and Reliability was based on the results from 991 normal developing children, 66 with speech and language disorders, and 33 with learning disabilities.
  • Test-retest reliability and Inter-scorer reliability was used on TACL-3 and for all three subtest.
validity
Validity

The TACL-3 has

  • Content-Description Validity
  • Construct-Identification Validity
administration
Administration
  • The examiner reads the stimulus out loud.
    • “Show me _____”
  • The subject is directed to point to which picture best represents the meaning.
  • No oral responses are required
  • Stimulus is given only once, except for children 5 years and younger.
    • FOR CHILDREN 5 AND UNDER: If child does not respond in 10 seconds, give the stimulus a second time.
administration continued
Administration continued
  • If subject does not correctly answer one of the three example items, then test should not be administered
  • Test begins after one example is answered correctly
  • Subtest should be administered in order
  • Always begin with the first item of each subtest and test until ceiling is achieved or final item is administered
  • Ceiling is achieved when child misses three items in succession

  • Examiner should consistently praise and encourage the examinee
  • Test administration takes 20-30 minutes
scoring
Scoring
  • Give a 1 for correct, 0 for incorrect
  • Record the raw score for each subtest on the score sheet.
  • Use appendix A to find the percentiles ranks and standard scores for each subtest.
  • Use appendix C to convert scores into age equivalences.
  • Use the sum of the standard scores from each subtest in appendix B to find the quotient score and overall percentile rank.
scoring continued
Scoring continued
  • Over all age equivalence can be calculated using the following formula

AE= (age in months) (TACL-3 quotient)
