Clinical Assessment of Articulation and Phonology®-2

How is CAAP-2 different from the original CAAP?
  • The population sample reflects 2013 U.S. Census data and includes children with speech delays and differences (7%).
  • The upper age limit increased to 11 years; 11 months (from 8;11).
  • The stimulus picture for “computer” was updated.
  • New validity studies comparing CAAP-2 to GFTA-2 and KLPA-2 were conducted.
  • The Error Difference Score was removed.
What is the population sample size for the CAAP-2?    The sample included 1,486 children across the U.S. and resembles 2013 U.S. Census data.
Does the CAAP-2 have norm-referenced scores?   Yes. The CAAP-2 provides three standard scores to qualify children. The Articulation Section has word and sentence standard scores, and the Phonology section gives an overall standard score. You can convert all standard scores to percentile ranks and age equivalents.
How long does the CAAP-2 take to administer?   For a young child (2;6–4 years of age) the CAAP-2 takes about 15 minutes to complete. Older children can complete the Consonant Inventory in about 10 minutes, and the School-Age Sentences section in about 5 minutes.
How do I use the CAAP-2 Pals and the Introductory Story?    This component of the assessment is optional. The Pals can be helpful with young children who may be apprehensive or difficult to “warm-up” prior to testing. You may also use the CAAP-2 Pals during play to obtain a language sample following testing. If you are testing an older child (> 5 years of age), you may want to skip the Introductory Story altogether. There are directions in the manual for administering the CAAP-2 with or without the Introductory Story.
When do I use the Phonological Process Checklist I?   The CAAP-2 has a Consonant Singleton Summary table on p. 2 of the Articulation Response Form. The sounds on this summary include Stops, Glides, Fricatives, etc. When filling out this chart, you'll begin to see error patterns. This makes it very easy to decide whether or not to use the Phonological Process Checklist.
When do I use Checklist II?   Use Checklist in conjunction with the Phonological Process Probes found in the back of the easel. It is very helpful in assessing children with severe phonological disorders. Additionally, Checklist II is useful as a re-test for specific processes you are presently treating. For example, if you have identified Gliding and Fronting as active processes and are intervening using a cycles approach, you can go back and probe these processes without having to administer the entire assessment.
Does the CAAP-2 assess non-developmental phonological processes?    Yes. There are reproducible checklists for Backing, Initial Consonant Deletion, Stridency Deletion, and Consonant Harmony in the appendices of the CAAP-2 manual. These inventories do not have normative data but can identify active processes (>40%).
Did you compare the CAAP-2 to other articulation tests?   Concurrent validity studies comparing CAAP-2 to the GFTA-2 and the KLPA-2 were significant beyond p<.01 for all raw scores, standard scores, and percentile ranks.
