Why is it recommended to administer the Receptive Communication subtest prior to the Expressive Communication subtest?
Statistically, we did not find practice effects based on subtest order for any subtests. The number of items that can be scored through observation of the child also minimises the likelihood of practice effects with the Communication subtests. However, there are some reasons for recommending that Receptive Communication be administered prior to Expressive Communication. Some stimulus items are similar across content and repeated exposure to these pictures may make it easier for the child to recognise them in the Receptive Communication subtest. In addition, many young children must establish rapport with the examiner before expressing themselves vocally by naming objects or speaking to the examiner; the Receptive items can help familiarise the child with tasks and encourage vocalisations.
