KSPT – Kaufman Speech Praxis Test for Children

This is not a comprehensive guide. Please refer to the manual when administering, scoring, and converting scores for this test and all other assessments. We hope this guide is a helpful tool for writing reports or refreshing your memory when choosing an appropriate test for a client.


The Kaufman Speech Praxis Test for Children (KSPT) is a standardized norm-referenced test that assists in the identification and treatment of CAS. It is normed for children ages 2;0 to 5;11. The KSPT has normative information related to populations of children with and without CAS. The assessment helps identify where the breakdown is in the speech system. The KSPT measures the child’s imitative response to the clinician and points to systematic course of treatment. The stimuli include syllables and words consisting of real and made up words. It is helpful in tracking the progress of motor-speech proficiency (Kaufman, 1995). No materials are needed besides the protocol.

Scoring & Subtests

The KSPT is standardized and provides a raw score, standard score, and percentile rank for each section of the test. The first section tests oral movement. Commands include protrude tongue, spread lips, pucker, and more. The second section includes pure vowels, diphthongs, simple consonants, reduplicated syllables, and several more tasks. The third section includes more complex tasks similar to those in the second section. The ability to do these tasks on command suggest that the motor center in the brain can communicate with the muscles involved in a smooth, coordinated fashion. Inability to do the tasks on command, suggests that there may be a breakdown in the motor pathways.

To score, mark the appropriate box if the child is unable to execute, gropes, has reduced range of motion, or is unable to isolate the single movement. If the child does the task with no problems, no score is given. The raw score is calculated by taking the total number in the section (e.g., section one has 11 tasks) and subtract the number of total errors. For example, there are 11 questions and the child misses 3, the raw score is 8.

Section 1: Oral Movement Level

There are 11 questions in this section. The child is asked to execute oral movements on command or by imitation. Tasks include: open mouth, protrude tongue, alternate tongue lateralization, spread lips, pucker lips, and others.

Section 2: Simple Phonemic/Syllabic Level

There are 10 sub-sections. Examples are below each sub-section.

A. Pure Vowels (V)

/a/ as in father; /i/ as in eat; /u/ as in boot

B. Vowel to Vowel (VV) – Diphthongs

/ou/ as in boat; /au/ as in out

C. Simple COnsonants (C)

/m/; /t/; /p/

D. Reduplicated Syllables (CVCV)

/mama/ (mama); /bubu/ (boo boo)

E. Consonant to Vowel (CV)

/du/ (do); /pe/ (pay); /mi/ (me)

F. VCV Movement

/apo/; /umə/

G. Repetitive Consonants with Vowel change (CV1CV2)

/mami/ (mommy);  /pʌpi/ (puppy)

H. Monosyllabics with Assimilation (CVC)

pop; mom; bib; tot

I. Simple Consonant Synthesis

/m/ – man – home; /p/ – pin – hop; /n/ – nap- bun

J. Bisyllabics with consonant and vowel change (C1V1C2V2)

happy, bunny, tuna

Section 3: Complex Phonemic/Syllabic Level

This section has 6 sub-sections. There are examples of each task below each sub-section.

A. COmplex Consonant Synthesis

/k/ – cup – book; /g/ – game – big; /f/ – fine – wolf

B. Blend Synthesis

/s/ blends: swing, smell, stop; /r/ blends: green, truck, frog; /l/ blends: black, clean, flag

C. C(F)VC(B)/C(B)VC(F) Synthesis

Front-to-back: duck, take; Back-to-front: cat, kid

D. Complex Bisyllabics (CVCVC)

wagon, chicken, zipper

E. Polysyllabic Synthesis (CVCVCV)

banana, umbrella, television, pʌtʌkʌ x3

F. Length and Complexity

win/window/windowsill; bar/barber/barbershop; soup/super/superman

WHEW! That’s a thorough test! There aren’t a ton of CAS assessments out there, but I really like this one. It doesn’t take very long to administer and gives some great information. Plus you can use it to track progress.
