When to Seek a Speech-Language Evaluation

An age-by-age guide to communication milestones and red flags, plus how to request an evaluation and what your rights are.

Age-by-Age Guide

Every child develops at their own pace, but there are general benchmarks that help us know when a child may benefit from evaluation. Here is a quick guide to what most children are doing at each age. Remember, these are averages — some variation is normal.

By 12 months: babbling with consonants (ba, da, ma), responding to name, waving/pointing
By 18 months: at least 5-20 words, following simple directions, pointing to show you things
By 24 months: 50+ words, starting to combine two words, following two-step directions
By 36 months: 200+ words, using 3-word sentences, understood by familiar people 75% of time
By 48 months: telling simple stories, asking questions, understood by strangers most of the time
By 60 months: using complex sentences, engaging in conversations, understood by everyone

Red Flags at Any Age

While some variation in development is normal, certain signs suggest you should not wait to seek an evaluation. These red flags warrant prompt assessment regardless of your child's age.

Loss of words, babbling, or social skills at any age (regression)
No pointing or gesturing by 12 months
No words by 16 months
No response to their name (consistently)
Lack of eye contact or social engagement
Not interested in other children by age 2-3
Significant frustration due to not being understood

Important

If your child has lost any skills they previously had — words, gestures, or social skills — seek evaluation immediately. Regression always warrants prompt assessment.

How to Request an Evaluation

You have the right to request a free evaluation through your public school system or Early Intervention program at any time. You do not need a doctor's referral. You can also self-refer to a private SLP. Here is how to access each option.

Birth to 3: Contact your state's Early Intervention program (free, federally mandated)
Ages 3-5: Contact your local school district for a free developmental evaluation
Private SLP: Search ASHA ProFind (asha.org) or ask your pediatrician for referrals
You can request an evaluation in writing to create a paper trail
The school district must respond to your request within a set timeframe (typically 60 days)

Tip

Put your request in writing. A simple email or letter saying 'I am requesting a speech-language evaluation for my child due to concerns about [specific concern]' creates a record and starts the clock.

What to Expect at an Evaluation

A speech-language evaluation typically takes 45 minutes to 2 hours. The SLP will play with your child, ask you questions, and use formal and informal assessments. The goal is to understand your child's current communication abilities and determine whether they need services.

Parent interview: your concerns, developmental history, daily communication
Hearing screening to rule out hearing loss
Standardized testing: formal assessments of receptive and expressive language
Play-based observation: how your child communicates naturally
Oral-motor examination: how the mouth muscles work for speech
A written report with results, diagnosis, and recommendations

Your Rights as a Parent

Parents have strong legal rights when it comes to accessing evaluations and services for their children. Whether through Early Intervention or the school system, these services are guaranteed by federal law (IDEA — Individuals with Disabilities Education Act).

You have the right to a free evaluation through the public system
You can request an evaluation at any time — you do not need a doctor's referral
The school cannot refuse to evaluate if you make a formal request
You have the right to an Independent Educational Evaluation (IEE) if you disagree with results
You have the right to participate in all decisions about your child's services
Services through Early Intervention and schools are provided at no cost to families

Early Intervention vs. School Services

The system changes when your child turns 3. Before age 3, services are provided through Early Intervention (Part C of IDEA). After age 3, services transition to the school district (Part B of IDEA). The transition can feel overwhelming, but understanding the process helps.

Early Intervention (birth-3): services are provided in your home or natural environment
School services (3-5): services may be in a classroom, preschool, or therapy room
The transition from EI to school typically begins at age 2.5 with a transition meeting
Your child must re-qualify for school services — EI eligibility does not automatically transfer
You can pursue both public and private services simultaneously
If your child doesn't qualify for school services, you can appeal or seek private therapy

Note

Don't wait until age 3 for the transition. Start the conversation with your EI coordinator at age 2.5 to ensure a smooth handoff to the school system.
