When Should a Child See a Speech Therapist?

Common reasons families seek a speech evaluation

Concerns that often prompt a referral to a speech-language pathologist include: a child who is significantly behind milestone ranges for words, phrases, or sentences; speech that strangers cannot understand at an age when clarity is typically expected; a child who seems to struggle to follow directions or understand what is said to them; stuttering that has persisted or worsened; a voice that sounds consistently hoarse or unusual; and difficulty with the social aspects of communication — like taking turns in conversation, staying on topic, or reading social cues. Any one of these is a reasonable reason to seek an evaluation.

The American Academy of Pediatrics recommends that clinicians perform language surveillance at every well-child visit and refer for speech-language evaluation when concerns arise 1Ref 1American Speech-Language-Hearing Association (2024).Spoken Language Disorders — Practice Portal.SLP scope of practice for language disorders; evaluation process (structured tasks, caregiver interview); play-based therapy for young children; parent coaching as core component.

Age-based language milestones

The AAP provides the following age-based language benchmarks for when concerns should prompt evaluation 2Ref 2American Academy of Pediatrics / HealthyChildren.org (2023).Language Delays in Toddlers: Information for Parents.AAP age-based language milestones (1 word by 12 months, 2-word phrases by 24 months, 50-word vocabulary by 24 months) and red flags that warrant referral:

• By 1 year: Should say at least one word; respond to their name; babble with intonation
• By 16 months: Should say at least one word beyond 'mama' and 'dada'
• By 24 months: Should say approximately 50 words and use two-word phrases ('Daddy go')
• Any age: Loss of previously acquired language skills warrants prompt evaluation

A practical benchmark for speech clarity: by age 2, a familiar caregiver understands most of what a child says; by age 3, a stranger should understand roughly half to three-quarters; by age 4, speech should be mostly clear to anyone 2Ref 2American Academy of Pediatrics / HealthyChildren.org (2023).Language Delays in Toddlers: Information for Parents.AAP age-based language milestones (1 word by 12 months, 2-word phrases by 24 months, 50-word vocabulary by 24 months) and red flags that warrant referral.

How to get an evaluation

There are several pathways. The most common for young children is a referral from the pediatrician at a well-child visit — parents can bring up concerns at any visit, not just scheduled ones. Children under age 3 in the United States may qualify for free evaluation and services through their state's Early Intervention program under Part C of IDEA, which does not require a physician referral — parents can contact the program directly 3Ref 3American Academy of Pediatrics / HealthyChildren.org (2023).What Is Early Intervention?.Free evaluation and services for children under 3 through IDEA Part C; parent-initiated referral accepted; speech therapy among services provided. Children 3 and older may qualify for services through the public school district. Families may also go directly to a private SLP practice.

A hearing test (audiogram) is often recommended before or alongside a speech evaluation, since hearing loss can cause or worsen speech and language delays.

What an evaluation looks like

An SLP evaluation is not a pass/fail test. It typically involves structured play, picture naming, following directions of increasing complexity, and informal observation of how a child communicates. The SLP also gathers a detailed history from caregivers — when concerns started, the child's health history, languages spoken at home, and any relevant family history. Depending on the child's age and concerns, the evaluation may focus on speech sounds, language comprehension and expression, fluency, voice, or social communication. Results are shared with families and, if therapy is recommended, a plan is discussed 1Ref 1American Speech-Language-Hearing Association (2024).Spoken Language Disorders — Practice Portal.SLP scope of practice for language disorders; evaluation process (structured tasks, caregiver interview); play-based therapy for young children; parent coaching as core component.

What speech therapy actually involves

For young children, therapy is almost always play-based and child-led — activities that target communication goals within games, books, or everyday routines. Frequency varies based on the nature and severity of the concern; some children benefit from brief, targeted courses of treatment, while others need longer-term support. Parent coaching is often a core part of therapy, particularly for toddlers, so that strategies learned in sessions carry over into daily life at home 1Ref 1American Speech-Language-Hearing Association (2024).Spoken Language Disorders — Practice Portal.SLP scope of practice for language disorders; evaluation process (structured tasks, caregiver interview); play-based therapy for young children; parent coaching as core component. Progress is monitored regularly and goals are updated as a child grows.
