The Kaufman Speech Praxis Test for Children was established through a grant from the former Research Institute of William Beaumont Hospital and published in 1995 through Wayne State University Press in Detroit, Michigan.

The KSPT is useful beyond establishing an initial diagnosis, as results can be used to measure and quantify gains in speech-motor proficiency. Also, test sections can assist in developing goals for IEPs and measuring progress. 

• Identifies where the child's speech system is breaking down and points to a specific course of treatment.
• Norm-referenced and standardized items that provide a raw score, standard score, and a percentile ranking.
• Provides normative information for the "normal" pediatric speaking population and the "disordered" population.
• Results assist in planning treatment, developing goals for IEPs, and measuring progress.
• Breakdowns in KSPT match the levels of treatment in the K-SLP Treatment Kits, allowing for a seamless transition to therapy.

No test actually informs us as to a specific diagnosis. Tests are a way to take data on the behaviors that are desired to evaluate. It is the role of the speech-language pathologist to then interpret the data and know the characteristics of CAS to then make a firm diagnosis.
