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 clinicalpopulations. 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 PhonologicalProcessing or CTOPP. The query returned 4,287 results.
Characteristics of the CTOPP-2
Uses of the CTOPP-2
The CTOPP-2 has four principal uses:
CTOPP-2 Composites
The CTOPP-2 yields six types of normative scores:
Percentile ranks are easily understood by parents and others with whom the examiner might want to share the results. Subtest scaled scores have a mean of 10 and a standard deviation of 3. The composite score indexes have a mean of 100 and a standard deviation of 15. Age and grade equivalents show the relative standing of individuals' scores. A new Rasch-based developmental score is now available for the non-speeded subtests.
Statistical Characteristics
Reliability of the CTOPP-2 subtests and composites was demonstrated by average internal consistency coefficients presented for the subtests that exceed .80 for all except Nonword Repetition with an average alpha of .77. The average internal consistency coefficients for the composites were all .85 or higher, a highly desirable level for reliability.
Validity of the CTOPP-2 subtests and composites was demonstrated by correlations to measures directly related to the constructs measured by the CTOPP-2. The averaged coefficients for the subtests range from .49 (moderate) to .84 (very large); those for the composites range from .65 (large) to .76 (very large) in magnitude.
Complete 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 online access to supplemental material, in sturdy storage box.
