The purpose of this work was to develop an articulation test which would be discriminating in the determination of velopharyngeal incompetency in young children. From 50 words containing the /p/ and /b/ sounds, normative data for children approximately 3 1/2 years of age were collected. From the responses of these children, 25 words were selected for a base test. Validity of the test is currently being determined.
