IS YOUR CHILD’S SPEECH ON TRACK?
A Parent's Guide to Early Language Assessment
As parents and caregivers, you’re always watching for signs that your child is growing and thriving. When it comes to communication, it’s natural to wonder, “Is my child on track?” At Brooklyn Letters, we believe that empowering you with knowledge is the first step toward building a strong foundation for your child’s success on their unique communication journey. Developing strong communication skills lays the groundwork not only for academic achievement but also for their confidence, social interactions, and emotional regulation.
This guide will walk you through what an early language assessment is, how a speech pathologist evaluates children, the role of play in understanding communication, and when you should consider professional early intervention.
Understanding Early Intervention: The Role of Speech Pathology for Your Child
An early language assessment is a comprehensive, play-based evaluation conducted by a licensed speech therapist (also known as a speech-language pathologist or SLP). This is a crucial first step in speech pathology and language pathology. It is not a test your child can fail, but rather a structured process designed to understand your child’s unique communication skills profile—strengths, areas for growth, and next steps for support, such as speech therapy or language therapy. This process is vital for identifying any developmental delays early on.
How Speech Pathology Experts Assess Communication in Children
A speech pathologist uses a combination of tools to assess speech and language in kids, including:
- Standardized Tests: These are norm-referenced assessments that compare your child’s performance to large groups of same-age peers. While useful for generating scores and identifying significant speech and language delays, standardized tests have limitations. They may not fully capture how a child communicates in everyday situations, particularly for very young toddlers or those from diverse backgrounds.
- Informal/Non-Standardized Measures: These provide equally valuable information about a child’s speech and language skills. Through observations, language sampling, and parent interviews, SLPs can compare your child’s skills to developmental data. This research-based data shows the typical ages at which most children achieve language development milestones. This naturalistic approach often reveals a more accurate picture of how your child truly communicates, helping to diagnose potential speech and language disorders. You can review some of the literacy milestones by age.
The Power of Play in Speech Development for Kids
Play is one of the richest windows into a child’s communication abilities, especially in early childhood. SLPs often reference frameworks like Weatherby’s play scale, which track how children use toys and objects in increasingly symbolic ways. For many kids, including those with autism or other developmental challenges, play-based therapy sessions are the most effective approach.
- Early play (sensorimotor): Mouthing, banging, or exploring objects.
- Functional play: Using objects for their intended purpose (e.g., rolling a toy car).
- Symbolic play: Pretending (e.g., feeding a doll, using a block as a “phone”).
Symbolic play is closely tied to the development of language skills. If a child can use an object to represent something else, they are developing the mental skills needed for language. During a play-based assessment for pediatric speech therapy, SLPs also observe vocabulary, grammar, nonverbal communication (eye contact, gestures), and pragmatic skills (turn-taking, having a conversation) in a natural setting.
Why Language Comes Before Speech
It’s important for parents to know that language development drives speech development. In other words, the more advanced a child’s understanding and use of language, the more sophisticated their speech and phonology will become.
- If a child has a language delay (for example, expressive language delay), they often also show delays in speech sound development.
- Parents may notice that their child “can’t say certain sounds” or “isn’t enunciating clearly,” but in many cases, the underlying issue is that the child’s language system itself is delayed. When vocabulary and sentence skills grow, sound development typically advances as well.
This is why skilled SLPs always evaluate language first, before focusing narrowly on speech.
Why Language Skills are the Foundation for Pediatric Speech
It’s important for parents to know that language development drives speech development. The more advanced a child’s understanding and use of language, the more sophisticated their articulation and phonology will become.
If a child has a language delay (for example, expressive language delay), they often also show delays in speech sound development. Parents may notice that their child “can’t say certain sounds,” but in many cases, the underlying issue is that the child’s language system itself is delayed. When vocabulary and sentence skills grow, sound development and clarity typically advance as well. This is why skilled SLPs in pediatric speech always evaluate language first.
Key Areas in a Speech and Language Assessment for Children
A comprehensive assessment looks at multiple areas:
- Receptive Language: This covers your child’s receptive language skills—how well they understand directions, questions, and words.
- Expressive Language: How your child communicates using gestures, words, and sentences (including Mean Length of Utterance [MLU], a measure of sentence complexity). You can find more data on expressive language and vocabulary charts here.
- Pragmatic Language: How your child uses language socially—eye contact, turn-taking, asking questions. Issues with fluency, such as stuttering, may also be noted here. You can learn more about general pragmatic milestones here.
- Speech Production/Phonology: How clearly your child produces sounds (speech intelligibility) and whether they have patterns of errors, known as speech sound disorders, that are age-appropriate. For a comprehensive overview, see our page on speech sounds.
Early Childhood Speech Development: Milestones and Tips for Parents
Here are a few reference points for early communication growth. Engaging in simple language activities at home can make a big difference.
- Vocabulary Growth: ~50 words by 18 months; two-word phrases by 24 months.
- Speech Intelligibility: ~50% understood by age 2, ~75% by age 3, ~90% by age 4. You can see a visual chart of these benchmarks here.
- Phonological Processes: Errors like “wabbit” for rabbit should resolve by ages 5–6; simpler errors, like leaving off final consonants (“ca” for cat), should resolve by age 3. You can see a chart with the typical ages of elimination for these processes.
(See this chart outlining when specific consonant sounds are typically acquired.)
Identifying a Potential Speech Delay: When to Seek Speech Therapy
Every child develops at their own pace, but consider an evaluation for a potential speech delay or other speech disorders if you notice these red flags. Strong parental involvement is key to early identification.
- No babbling by 9 months.
- No words by 15–18 months.
- No two-word combinations by age 2.
- Less than 50 spontaneous words/approximations by 24 months.
- Difficulty following simple directions.
- Persistent speech errors beyond expected ages.
- Ongoing frustration during communication.
After the Assessment: Navigating Therapy and Early Intervention
If the assessment indicates that your child would benefit from support, the SLP will recommend a plan that may include therapy. This plan will outline specific therapy goals and strategies. Family involvement is crucial for success, as progress made in therapy is best reinforced at home. This collaborative approach is also a cornerstone of special education programs, ensuring that individuals with disabilities receive comprehensive support. Following the evaluation, your family will have clear next steps and valuable tips for parents to help your child thrive.
