CTOPP is suitable for Access Arrangements >

The Comprehensive Test of Phonological Processing (CTOPP) assesses phonological awareness, phonological memory and rapid naming. Individuals with deficits in one or more of these kinds of phonological processing abilities may have more difficulty learning to read than those who do not. The CTOPP was developed to aid in the identification of individuals from nursery through to college who may profit from instructional activities to enhance their phonological skills.

The CTOPP has four principle uses:

  • To identify individuals who are significantly below their peers in important phonological abilities
  • To determine strengths and weaknesses among developed phonological processes
  • To document an individual's progress in phonological processing as a consequence of special intervention programmes
  • To serve as a measurement device in research studies investigating phonological processing.

The CTOPP consists of 13 subtests:

  • Elision
  • Blending words
  • Sound matching
  • Memory for digits
  • Nonword repetition
  • Rapid colour naming
  • Rapid digit naming
  • Rapid letter naming
  • Rapid object naming
  • Blending nonwords
  • Phoneme reversal
  • Segmenting words
  • Segmenting nonwords
