Description:
The Peabody Picture Vocabulary Test - Third Edition (PPVT-III) updates the PPVT of 1959 and the PPVT-R of
1981, and like them is an individually administered, un-timed, norm-referenced, wide-range test with two parallel
forms. The 204 items on each form are grouped into 17 sets of 12 items of 4 black and white illustrations forming
a picture plate. The original PPVT used 300 stimulus words, 150 on each form of the test. In the development of
the PPVT-III item pool, national tryouts were used to eliminate stimulus words that were biased by gender, region,
race or ethnicity. The test has two parallel forms, requires no oral or written responses and no reading by the
examinee.
Scoring:
Rapid and objective scoring is done while the test in being administered. Raw scores are converted into
normative scores.
Reliability:
The alpha reliabilities for the 25 standardized age groups were between .92 and .98 with a median reliability of
.95 for both forms. The split-half reliabilities for the 25 age groups ranged from .86 to .97, with a median of .94 for
both forms. The altenate forms reliabilities range from .88 to .96 with a median correlation of .94.
Validity:
Correlations of the PPVT-III form A and B scores with scores of the WISC-III VIQ are .91 and .92; with the KAIT
Crystallized IQ, .87 and .91; and with the K-BIT Vocabulary score, .82 and .80. Slightly lower correlations with the
non-verbal scores were predicted; with the WISC-III PIQ .82 and .84; KAIT Fluid IQ, .76 and.85, and with the
K-BIT matrices score, .65 and .62. Full scale IQ on the WISC-III was .90 and .90, KAIT Composite IQ was .85
and .91, K-BIT composite, .78 and .76.
Norms:
The normative sample included 2725 persons. And while the original PPVT was standardized only on white
children from Tennessee, the normative sample of the PPVT-III was selected to match the data of the 1994 US
Census. The sample was stratified with each age group by gender, race/ethnicity, geographic region, and SES.
Only individuals who were determined to speak and understand English were included in the testing
Suggested use:
The PPVT-III is useful in testing preschool children for vocabulary acquisition as an indicator of linguistic and
cognitive development. When English is the language of home, school, and community, it can be used as a
screening device for verbal ability and for giftedness and for mental retardation. It is a useful test for people who
perform poorly on group tests, or for nonreaders and for those with written language problems. For individuals
with language impairment, it can provide a measure of linguistic potential, and it is useful for those who are
autistic, withdrawn, or have psychotic problems, as speech is not required. Individuals with cerebral palsy or with
visual-perceptual problems can also take this test.
