The Kaufman Speech to Language Protocol (K-SLP)

Developed by Nancy Kaufman, The Kaufman Speech to Language Protocol (K-SLP) is an evidenced-based assessment and treatment approach for children with Childhood Apraxia of Speech (CAS), speech sound disorders, and expressive language challenges. This approach simplifies the task of producing spoken language by teaching word approximations as a starting point using sounds the child is able to produce. From these word approximations, children become successful at conveying meaningful messages and they can then progress to producing whole words, phrases, and sentences.

Stages of Intervention may include:

  • Defining the desired behaviour 

  • Establishing Motivation

  • Modelling and Cueing

  • Implementing Errorless Teaching/Learning

  • Understanding Shaping

  • Mixing and Varying Tasks

  • Practicing the New Skill

  • Practicing in the Child's Natural Environment

This therapy can potentially be used to treat the following:


CAS is a motor speech disorder, probably of genetic origin, affecting the individual’s ability to voluntarily make the right movements during speech.
