EOWPVT- Expressive One-Word Picture Vocabulary Test - 2000 Edition

The Expressive One-Word Picture Vocabulary Test (EOWPVT) is an individually administered, norm-referenced test that provides an assessment of an individual's English speaking vocabulary. It is standardized for use with individuals ages 2-0 through 18-11.

This edition of the EOWPVT includes national norms based on a representative sample of more than 2,000 individuals residing in the United States. The test has also been conormed with the Receptive One-Word Picture Vocabulary Test (ROWPVT) so that meaningful comparisons can be easily made between an individual's expressive and receptive language. Other notable changes to this edition include the addition and replacement of many test items as well as new administration procedures that permit the examiner to prompt or cue examinees so that they will attend to the relevant aspects of each illustration. Additionally, all illustrations have been newly rendered in full color with drawings that are easy to interpret and that better hold the examinees' interest.

Administration and Scoring
To administer the test, the examiner presents a series of illustrations depicting objects, actions, or concepts. The examinee is asked to name each illustration. The test begins at a point at which the examinee is expected to meet with success in naming each illustration. The examiner then presents items that become progressively more difficult. When the examinee is unable to correctly name a number of consecutive illustrations, testing is discontinued. Total time for administration and scoring is typically 15 to 20 minutes. Raw scores can be converted to standard scores, percentile ranks, and age equivalents.The components of the complete EOWPVT include the manual, a series of test plates bound in a spiral booklet with a fold-out easel, and a package of record forms.
