Suitable for Access Arrangements and DSA Applications

The Comprehensive Test of Phonological Processing, Second Edition (CTOPP-2) is designed to assess phonological awareness, phonological memory and rapid naming.

The CTOPP-2 has four principal uses 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
  4. Serve as a measurement device in research studies investigating phonological processing.

Features of CTOPP-2

  • New normative data collected for individuals aged 6 years to 24 years.
  • A new subtest Phoneme Isolation now combines with Elision and Blending Words to make up the Phonological Awareness Composite from 7 years upwards.
  • Additional easier items have been added allowing the CTOPP-2 to be administered from 4 years of age. 

Scores Available

The CTOPP-2 yields six types of normative scores: age and grade equivalents, percentile ranks, subtest scaled scores, composite indexes, and developmental scores.
