Comprehensive Test of Phonological Processing - Second Edition (CTOPP-2)

Age range: 4 through 24 years 11 months

Qualification level: B

Year: 2013

Administration time: 40 minutes

Administration type: Individual; Manual scoring

The Comprehensive Test of Phonological Processing (CTOPP) was published in 1999 and revised in 2013 to meet the need for an assessment of reading-related phonological processing skills.

Clinicians can use the CTOPP-2 to:

1. Identify individuals who are significantly below their peers in important phonological abilities,

2. Determine strengths and weaknesses among developed phonological processes,

3. Document individuals' progress in phonological processing as a consequence of special intervention programs, and

4. 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 Colour Naming measures the ability to rapidly name colours.

12. Rapid Object Naming measures the ability to rapidly name objects.
