Valid And Reliable

The ROWPVT-4 is a valid and reliable instrument. The standardization sample includes more than 2,400 children and adults ages 2 years, 0 months to103 years from 26 states in the U.S. The standardization sample closely resembles the demographics of the U.S. population. It has a high degree of reliability for Internal Consistency, ranging from 0.94 to 0.98 for the various age groups, with a median of 0.97 across all ages. The test-retest correlation for raw scores is 0.97 and 0.91 for standard scores. The validity data support this test as an instrument for assessing vocabulary abilities across a wide range of ages.
