A Standardized Assessment of Phonological Awareness, Phoneme-Grapheme Correspondence, and Phonemic Decoding Skills
Test results help educators focus on those aspects of oral language that may not be systematically targeted in classroom reading instruction.
Features and benefits
- Measures students' awareness of spoken syllables and phonemes.
- Assesses students' knowledge of sound/symbol correspondence in isolation and in practice.
- Includes a wide variety of tasks that correlate with success in early reading and spelling.
- Straightforward developmental format lets examiners tease out specific skills and plan effective interventions.
- The Examiner's Manual has been reorganized and rewritten to provide more detailed information about the administration, interpretation, and statistical characteristics of the test.

Test structure
- Includes six core subtests (Rhyming, Segmentation, Isolation, Deletion, Substitution, and Blending) and two supplemental subtests (Phoneme-Grapheme Correspondence and Phonemic Decoding).
- Each item was evaluated using both conventional item analysis and differential analysis.
- The Total Score is divided into a Phonological Awareness Index and a Phoneme-Grapheme Index.
Technical information
- New normative scores for the subtests were calculated in terms of scaled scores that have a mean of 10 and a standard deviation of 3.
- Subtests and composite scores were thoroughly examined for floor and ceiling effects.
- Criterion-prediction validity is evidenced by correlations with and comparison of mean and standard deviations of the CTOPP-2 Phonological Awareness Composite Score.
- Reliability and validity studies were conducted with individuals with typical language ability and those who had been previously diagnosed with a language impairment or received other special education services.
- Average coefficient alpha ranges between .83 and .92 for the subtests and is .96 for the Phonological Awareness Index and .97 for the Phoneme-Grapheme Index.
