Description: The Comprehensive Test of Phonological Processing (CTOPP) was published in 1999 to meet the need for an assessment of reading-related phonological processing skills. Since its initial publication, the CTOPP has been popular with professionals in psychology and education. It has been used in many studies of reading and phonological processing in both typical and clinical populations. The extent of its widespread adoption and usage is evident from the results of a recent search of the PsychInfo database for research studies using the terms Comprehensive Test of Phonological Processing or CTOPP. The query returned 4,287 results. Characteristics of the CTOPP-2 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. 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. CTOPP-2 Subtests: 1. Elision measures the ability to remove phonological segments from spoken words to form other words. 2. Blending Words measures the ability to synthesize sounds to form words. 3. Sound Matching measures the ability to select words with the same initial and final sounds. 4. Phoneme Isolation measures the ability to isolate individual sounds within words. 5. Blending Nonwords measures the ability to synthesize sounds to form nonwords. 6. Segmenting Nonwords measures the ability to segment nonwords into phonemes. 7. Memory for Digits measures the ability to repeat numbers accurately. 8. Nonword Repetition measures the ability to repeat nonwords accurately. 9. Rapid Digit Naming measures the ability to rapidly name numbers. 10. Rapid Letter Naming measures the ability to rapidly name letters. 11. Rapid Color Naming measures the ability to rapidly name colors. 12. Rapid Object Naming measures the ability to rapidly name objects. Please contact us for link to audio recording subtest.
