The PTAP is an easy-to-administer articulation and phonology assessment or screening tool that takes only 2 to 8 minutes to administer. It helps a clinician make a differential diagnosis among articulation delay, phonological disorder, or a combination of the two. The PTAP assesses 23 phonemes and 7 phonological processes with 36 color photos (4 panels of 9 pictures each) that show real-life objects of basic vocabulary words. The protocol has all of the transcription and phonological analysis provided for each word, making the scoring quick and easy. An oral motor exam is also included.
Phonological processes assessed include:
- Cluster reduction
- Initial consonant deletion
- Weak consonant deletion
- Final consonant deletion
- Syllable reduction
Administration and Scoring
The PTAP is an individually administered, empirically based assessment that can be administered and scored in approximately 5 to 15 minutes. The child’s articulation errors are marked on the transcribed target words on the form. Any errors of phonological processes are recorded in the column of that phonological process on the protocol.
