Auditory Processing Disorder Assessment Suite (APD Suite)

The Sound Scouts APD Suite is a battery of tests designed to assess auditory processing abilities in children (and adults). A unique feature of the tests in the Suite is that they use the concept of differential testing to narrow down the range of deficits that could cause scores on a particular test to be deficient.

The differential testing method assists clinicians in determining when the difficulty a client experiences in understanding speech has been the consequence of some type of auditory processing deficit, versus when it is the consequence of a cognitive deficit or a language deficit. The tests were developed by Dr Sharon Cameron and Dr Harvey Dillon and the IP has been licensed from Macquarie University.

For a more detailed overview of the four tests in the suite, LiSN-S, LiSN-U, DDdT and DigiSpan, see the Background Information sections of each test below. A list of peer-reviewed research publications for each test, with links to abstracts and/or full texts, can be accessed for each one.
