Overview of the Test: The Expressive Vocabulary Test, or EVT-2 is similar to the PPVT-4. Instead, the EVT-4 measures an individual’s expressive vocabulary and word retrieval abilities. The EVT-2 takes about 10-20 minutes, on average, to complete; however, the time for completion can vary from individual to individual. On each page, there is a color picture which coincides with a question. The individual administering the test asks a predetermined question to the individual taking the test. The individual taking the test can respond in multiple ways, whatever may be appropriate for the question given. There are 190 items in the EVT-2, and each page increases in difficulty, accordingly. Many different concepts are covered in the pages of the EVT-2, including various categories of vocabulary and different parts of speech. There are two forms of the EVT-2: Form A and Form B.
Purpose of the Test: The primary purpose of the EVT-2 is to measure an individual’s expressive vocabulary and word retrieval. The EVT-2 can also measure potential language impairments and an individual’s verbal language development over time.
Age Levels: The EVT-2 is designed for ages 2 years and 6 months up to 90 years

Psychometric Properties: The psychometric properties of the EVT-2 are the same as the PPVT-4. 5,500 individuals from age 2 years and 6 months to age 90+ were tested over a period of 5 years. Out of those tested, 3,500 of the scores were used to match the demographics of the US Census. The test has reliability in the .90s.
To whom this test is best suited for: This test can almost be used for everybody because of the wide variety of age level. This test can also be used for individuals with communication barriers because it does not require the test taker to read and write; however, it might be more difficult to test an individual who has limited verbal communication. As stated in the EVT-2 summary form, this test underwent extensive evaluation to make sure there is no bias toward a number of different demographics. Since this test requires an individual to respond to questions based on a picture, it is not suitable for those with complex vision impairments.
Reflection: In the future, I would use this test for individuals who are “more advanced” than the Peabody Picture Vocabulary Test. Since the prompts in Peabody Picture Vocabulary test are relatively simple, and individual who is excelling at the PPVT-4 can instead be assessed on their expressive vocabulary. The prompts in this test are more complex, and require the test taker to have more verbal communication skills, so I would use this test on students who meet that criteria.
