Nancy Kaufman's K-SLP Method
Kaufman Speech to Language Protocol (K-SLP) is the #1 tool used to treat childhood apraxia of speech in the US. It is an evidenced-based evaluation and treatment method that shapes a child’s best approximation of words toward full adult forms, and then into functional, expressive, and social language. The method was created by Nancy R. Kaufman in 1979 and has continued to evolve in the years since, with therapy materials added to reach kids of all types and abilities.

We are so pleased with the progress our son has made. About a month ago, had maybe 25 words. Today, with the use of approximations, he's upwards of 75-100. He is so happy, and not nearly as frustrated, meaning he’s behaving much better.

Kaufman Speech to Language Protocol was created by Nancy Kaufman and is at the heart of speech and language programs used at Kaufman Children's Center to treat childhood apraxia of speech (CAS), other speech sound disorders, and expressive language challenges.
K-SLP focuses upon the child’s speech-motor skills, beginning by shaping the consonants, vowels, and syllable shapes/gestures that they are capable of producing. Treatment then moves toward higher levels of speech-motor coordination, giving them a functional avenue to become an effective vocal communicator.
KAUFMAN SPEECH TO LANGUAGE PROTOCOL...
- Is rooted in teaching strategies from applied behavior analysis and principles of motor learning.
- Corresponds with the most current research in CAS, neuroscience, sensory-motor development, and early language development.
- Includes techniques gleaned from what is known about acquired apraxia of speech.
- Implements phonological processes to simplify the motor planning of challenging words, shaping through successive approximations toward perfect articulation and age-appropriate expressive language.
