The Clinical Assessment of Articulation and Phonology (CAAP-2)



This semester (Spring 2019) many of you are using the Clinical Assessment of Articulation and Phonology-2 to evaluate and get baseline information on your clients.

Some of the fun benefits of this particular test are the little figures that come as part of the test. For some of our younger students, they enjoy being able to manipulate the figures.

The test can be administered in about fifteen to twenty minutes. It is easy to interpret and to get both a standard score for sounds as well as a phonological inventory that will assist you in making a choice of clinical treatments. The test can be purchased through SuperDuper Publications.

One problem that I am seeing in reading the write-ups of the evaluations is that although there are two types of scores many of you are confusing the two measurements. To avoid confusion I have put a sample of what you might write for the write-up. Think about how this test gives you these very clear tables on the score form. We should use these then in our write-ups

Clinical Assessment of Articulation and Phonology (CAAP):  The CAAP is a norm-referenced instrument designed to assess English articulation and phonology in preschool and school-age children.  The CAAP provides two types of standard scores that measure articulation competence.  These are (1) a Consonant Inventory Score and (2) a School Age Sentence Score.

Age scores are the least reliable and therefore we don’t include them on our reports.

The Phonological Checklists provide two types of scores that measure the occurrence of phonological processes.  The first is a simple percentage of occurrence approach used for sampling phonological processes.  Measures greater than 40% are considered significant.  The second type is a standard scored based upon the responses to the Phonological Process Checklists. All standard scores have a mean of 100 and a standard deviation of 15.
