Apraxia

Apraxia: Speech and Language Assessment

Childhood Apraxia of Speech, often called CAS, is a motor speech disorder that affects a child’s ability to plan and coordinate the precise movements needed for speech. A child with CAS may know what they want to say, but have difficulty producing sounds, syllables, or words clearly and consistently. This is different from a child simply “not wanting” to speak or having a general speech delay.

A speech and language assessment can help identify whether a child’s communication difficulties may be related to Childhood Apraxia of Speech, another speech sound disorder, a language delay, autism-related communication differences, selective mutism, or a combination of factors. Because speech and language development is complex, a thorough assessment is an important first step in understanding the child’s strengths, needs, and appropriate next steps for support.

What Is Included in a Speech and Language Assessment?

Speech and language assessments are completed by Speech-Language Pathologists, also known as SLPs. An SLP may use a combination of formal and informal tools to understand how a child communicates across different areas, including speech sound production, expressive language, receptive language, social communication, and overall communication skills.

Assessment may include:

• Reviewing parent or caregiver concerns and developmental history
• Observing the child’s communication during play or conversation
• Evaluating how the child understands words, questions, and instructions
• Assessing how the child uses words, phrases, sentences, gestures, or other communication methods
• Looking at speech clarity, sound errors, syllable patterns, and consistency of speech production
• Completing an oral mechanism examination to observe the structures and movements used for speech
• Using standardized speech or language tools when appropriate
• Gathering information from parents, teachers, or other professionals involved in the child’s care

For children with suspected Childhood Apraxia of Speech, the SLP may pay close attention to how the child plans and sequences speech movements. Some children may produce a word correctly one time but have difficulty producing it again. Others may show increased difficulty as words become longer or more complex.

Understanding Related Communication Concerns

Apraxia is not the same as autism, non-speaking autism, or selective mutism. However, these concerns can sometimes overlap, and a careful assessment can help clarify what may be contributing to a child’s communication profile.

Autism Spectrum Disorder is a neurodevelopmental diagnosis that may involve differences in social communication, play, flexibility, sensory processing, and patterns of behaviour or interests. Some autistic children use limited spoken language or communicate in other ways, such as gestures, visual supports, or augmentative and alternative communication.

Selective mutism is typically understood as an anxiety-related condition where a child may speak comfortably in some settings, such as at home, but have significant difficulty speaking in other settings, such as school or community environments.

A speech and language assessment does not replace every type of diagnostic evaluation, but it can provide valuable information about the child’s communication abilities and whether additional referral or collaboration may be helpful.

Diagnosis and Recommendations

In some cases, a Speech-Language Pathologist may be able to identify Childhood Apraxia of Speech during the initial assessment. In other cases, especially with very young children or children who use few spoken words, diagnosis may require ongoing observation or a period of therapy.

After the assessment, families typically receive a summary of findings and recommendations. These may include speech therapy, language therapy, home practice strategies, visual supports, school-based recommendations, or consideration of augmentative and alternative communication when appropriate.

Progress for children with motor speech difficulties can take time. Therapy often requires consistency, repetition, and collaboration between the child, family, therapist, and other care providers. The goal is to build a supportive plan that respects the child’s abilities while helping them develop clearer and more effective communication.

If you have concerns about your child’s speech, language development, or possible Childhood Apraxia of Speech, contact the clinic to ask about speech and language assessment, therapy options, and current service availability.
