What population sample size?
Over 1700 students from the US and Canada in 32 states and three provinces participated in the standardization. The CAAP®
population sample closely resembles 2000 US census data in terms of race, gender, and age.
Does CAAP® have norm-referenced scores?
provides you with three standard scores to qualify children. The Articulation Section has a word and sentence standard score and the Phonology section also gives an overall standard score. All standard scores may be converted to percentile ranks and age equivalents.
How long does the CAAP® take to administer?
For a young child (2;5-4 years of age) the CAAP®
takes about 15 minutes to complete. Older children can complete the Consonant Inventory in about 10 minutes, and the sentence section in about 5 minutes.
How do I use the CAAP® Pals and the Introductory Story?
This component of the assessment is optional. It is helpful with young children who may be apprehensive or difficult to "warm-up" prior to testing. You may also use the CAAP®
pals in 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®
with or without the Introductory Story.
Why are there two summary tables on the Articulation Inventory?
The Consonant Singleton Summary on p. 3 of the Articulation Inventory is for the SLP to establish goals and decide whether or not to use the Phonological Process Checklist. The Consonant Singleton Index on p. 4 is a simplified version of the Summary on p. 3 and is easier for parents to understand. Simple explanations for filling out these charts are located in the manual.
How did you choose the words, sentences, and pictures for the CAAP®?
Prior to the standardization, there was a pilot study and a field study. In both studies, children identified over 100 words and imitated 25 sentences. From this larger sample, the words and sentences that best identified children with articulation errors were chosen through item analysis.
When do I use the Phonological Process Checklist I?
has a Consonant Summary table on p. 3 of the Articulation Inventory. The sounds on this summary are divided into Stops, Glides, Fricatives, etc. When you fill 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 I or II?
You use Checklist II in conjunction with the Phonological Process Probes found in the back of the easel. It is meant for children with severe phonological disorders. Additionally, you may use Checklist II as a re-test for specific processes that you are presently treating. For example, you may have identified Gliding and Fronting as active processes and are intervening using a cycles approach. You can simply go back and probe those specific processes without having to administer the entire assessment.
Did you compare the CAAP® to another articulation test?
Yes. The CAAP®
was compared to the Bankson-Bernthal Test of Phonology
(BBTOP) in a concurrent validity study on 49 children with phonological process disorders. Essentially, the CAAP®
identified the same processes as the BBTOP
Can I review the CAAP® test?
Yes. Have the supervisor of your district, school, or speech department fax your request on company/school letterhead (1-800-978-7379), and we will send you a review copy. You may also email the request to Customer Help at
or contact Customer Help at 1-800-277-8737.

May I purchase the Stimulus Easel separately?
No. At this point, you may purchase the record forms, manual, CAAP®
Pals separately, but not the easel.
