Phoneme Deletion
This test measures phoneme awareness (that is, speech sound manipulation) skills, in particular analysis of nonwords differing in levels of phonological complexity. Targeted phonemes are initial consonants (onsets) and final consonants (codas).
Age range
Suitable for children in Year 1 who show mastery (> 80%) on the Phoneme Isolation test, and for children in the age range of 6 to 12 years (i.e., UK Years 2 to 6).
Scoring: accuracy, speed
Accuracy and speed are measured. Accuracy is the more meaningful measure on any part of the test (Onsets, Codas, Total) where children have not yet reached mastery (> 80%) in accuracy. The speed measure is most meaningful for children who have reached mastery level in accuracy.
Norms
Grade norms are currently available for Year 1 (accuracy) and Year 2 (accuracy and speed).
