All-in-one expressive and receptive vocabulary test! Testing Time: 30 minutes (15 for each section) Research tells us that children with large, rich vocabularies have better verbal, reading, and writing skills. MAVA evaluates a child’s knowledge of basic (tier one), high frequency (tier two), and curriculum-based (tier three) words. This assessment includes, up-to-date word choices, full-color illustrations, and everything else you need to evaluate the listening and speaking vocabulary of children ages 3-0 to 12-11. Valid and Reliable The standardization samples for the MAVA included over 1,300 children for the receptive test and over 1,200 for the expressive test. Test-retest, inter-rater reliability, and concurrent validity are all very high and over .90. In comparing the tests of the MAVA to the Receptive One-Word Picture Vocabulary Test and the Expressive One-Word Picture Vocabulary Test, we found that the tests examine similar skills.
