l   Test-retest reliability and Inter-scorer
    reliability was used on TACL-3 and for all
    three subtest.
Validity
The TACL-3 has
l   Content-Description Validity
l   Construct-Identification Validity
Administration
l   The examiner reads the stimulus out loud.
    l    “Show me _____”
l   The subject is directed to point to which
    picture best represents the meaning.
l   No oral responses are required
l   Stimulus is given only once, except for
    children 5 years and younger.
    l   FOR CHILDREN 5 AND UNDER: If child does not
        respond in 10 seconds, give the stimulus a
        second time.

    three example items, then test should not be
    administered
l   Test begins after one example is answered
    correctly
l   Subtest should be administered in order
l   Always begin with the first item of each subtest
    and test until ceiling is achieved or final item is
    administered
l   Ceiling is achieved when child misses three
    items in succession
Administration continued

DEMONSTRATION
Scoring
l   Give a 1 for correct, 0 for incorrect
l   Record the raw score for each subtest on the
    score sheet.
l   Use appendix A to find the percentiles ranks
    and standard scores for each subtest.
l   Use appendix C to convert scores into age
    equivalences.
l   Use the sum of the standard scores from
    each subtest in appendix B to find the
    quotient score and overall percentile rank.
Scoring continued
l   Over all age equivalence can be calculated
    using the following formula

    AE= (age in months) (TACL-3 quotient)
                   100

l   The client will increase the use of adjectives
