When to See a Speech-Language Pathologist: A Parent's Guide

From 12 months to 3 years, these are the developmental signs that tell you it's time to contact a speech-language pathologist.

Written by The Praxis Path Editorial TeamLast verified Editorially reviewed

Cross-checked against the current ETS Praxis 5331 Speech-Language Pathology Test at a Glance and ASHA CCC-SLP standards.

Quick answer

Parents should see a speech-language pathologist if their child is not meeting speech and language milestones, is not understood by family or peers, or shows signs like stuttering, hoarseness, feeding difficulties, or social withdrawal. Early evaluations can be done through early intervention, schools, or private practices.

  • By 18 months, children should use at least 20 words
  • By 2 years, children should combine two words and use 50+ words
  • School districts evaluate children 3 and up for free
  • Early intervention programs serve children under 3

It is normal for children to develop at different rates, but some signs suggest a speech or language delay that would benefit from a professional evaluation. If you are worried, the safest path is to talk to your pediatrician or contact a speech-language pathologist directly.

By age: signs that warrant an SLP evaluation

12 months

  • Not babbling or using many sounds
  • Not responding to their name consistently
  • Not making eye contact or using gestures like pointing or waving

18 months

  • Fewer than 20 words
  • Not pointing to show you things
  • Losing words or sounds they previously used

2 years

  • Fewer than 50 words
  • Not combining two words together
  • Not understood by caregivers most of the time

3 years

  • Speech mostly unintelligible to strangers
  • Not using three-word sentences
  • Difficulty following simple directions

Other reasons to see an SLP

Speech and language delays are not the only reasons families seek help. You may also want an evaluation if your child:

  • Stutters or repeats sounds frequently
  • Has a hoarse, raspy, or unusually quiet voice
  • Has difficulty swallowing or eating safely
  • Is socially withdrawn or has trouble interacting with peers
  • Has a diagnosed condition such as autism, cleft palate, or hearing loss
  • Is falling behind in reading or writing

Do you need a referral?

In many states, you can call a speech-language pathologist or an early intervention program directly without a referral. Private practices often accept self-referrals. School districts evaluate children ages 3 and up for free through special education services.

What happens at the first appointment?

  1. Case history: The SLP asks about birth history, milestones, medical concerns, and family concerns.
  2. Play-based observation: For young children, evaluation often looks like play while the SLP listens and notes communication.
  3. Standardized testing: For older children, the SLP may use formal tests to compare skills to same-age peers.
  4. Recommendations: The SLP explains whether therapy is needed, how often, and what goals to target first.

Bottom line

If you are worried, trust your instinct. An evaluation does not commit you to therapy, and early help makes the biggest difference. Most children who receive early intervention make meaningful gains.

Frequently asked questions

How do I know if my child needs speech therapy?
If your child is missing milestones, hard to understand, frustrated with communication, or showing signs like stuttering or hoarseness, an evaluation is appropriate.
Do I need a doctor's referral to see an SLP?
Not always. Many states allow direct access to a speech-language pathologist, and school districts provide evaluations without a referral.
At what age should a child see a speech therapist?
Children can be evaluated as early as 12 months if there are concerns. Early intervention is especially effective before age 3.
What happens at a first speech therapy evaluation?
The SLP gathers history, observes play and communication, and may use standardized tests to compare your child's skills to age norms.
