Phonological Assessment and Treatment Targets (PATT) 2.0

PATT is a protocol originally developed in 2010 by Jessica Barlow, Jennifer Taps Richard and Holly Storkel for conducting a thorough assessment of a child’s speech in order to strategically select treatment targets based on the child’s presenting sound system, linguistic principles, and treatment efficacy research. PATT was revised for English and Spanish in 2024 to PATT Version 2.0 by Jessica Barlow, Jennifer Taps Richard, and Philip Combiths to simplify and update the protocol based on current research.

AutoPATT

An automated version of the PATT, known as AutoPATT, has been developed by Philip Combiths and Ray Amberg. This is a plug-in for Phon, free phonological analysis software, available for Windows and MacOS, created by Yvan Rose and Greg Hedlund.

Disclaimer: AutoPATT (and PATT) will select an ideal target that is predicted to lead to widespread gains in the child’s system, but it does not also include clinical judgment, for which there is no substitute. Consider these as tools for assisting — rather than dictating — target selection.

English and Spanish speech probes for eliciting samples to complete PATT are available here:

Many resources for phonological assessment, including additional single-word probes, are also available at Jennifer Taps Richard’s website, SLPath.com.
