The Comprehensive Test of Phonological Processing - Second Edition (CTOPP-2) assesses phonological processing skills. It has been popular with professionals in psychology and education. The CTOPP-2 has four principal uses: (1) to identify individuals who are significantly below their peers in important phonological abilities, (2) to determine strengths and weaknesses among developed phonological processes, (3) to document individuals' progress in phonological processing as a consequence of special intervention programs, and (4) to serve as a measurement device in research studies investigating phonological processing.
For this second edition, all new normative data were collected in 2008 and 2009. The test was normed on 1,900 individuals ranging in age from 6 through 24 years. The demographic characteristics of the sample conform to those of the population reported in the Statistical Abstract of the United States, and are, therefore, representative of the U.S. population.
The floor effects present in the 5- and 6-year-old version of the first edition have been eliminated by the addition of easier items and the ceilings were extended by the addition of more difficult items. The results of the item additions were so successful that it now is appropriate to administer the CTOPP-2 to 4-year-olds. The lower version of the CTOPP-2 now covers the 4- to 6-year-old range. A new phonological awareness subtest called Phoneme Isolation was added. The model of phonological processing abilities was clarified. Confirmatory factor analyses were carried out and justified the presence of rapid naming subtests on a test of phonological processing. The model for 4- to 6-year-old range was revised by adding rapid naming of digits and letters to this version, and reporting scores on both symbolic and non-symbolic rapid naming at this level.
Offers Phonological Awareness Composite Score (PACS), as well as percentiles, standard scores, and age and grade equivalents.
Kit includes Examiner's Manual, 25 Examiner Record Booklets for Ages 4 to 6, 25 Examiner Record Booklets for Ages 7 to 24, Picture Book, and 2 CDs.
