Ctopp-2: Comprehensive Test of Phonological Processes (The Comprehensive Test of Phonological Processing (CTOPP))

Ages: 4-0 through 24-11 Testing Time: 40 minutes Administration: Individual 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. COMPLETE CTOPP-2 KIT INCLUDES: Examiner's Manual, 25 Examiner Record Booklets for ages 4 through 6, 25 Examiner Record Booklets for ages 7 through 24, Picture Book, and 2 CDs, all in a sturdy storage box.
