Key Takeaways
- Developmental screenings are brief assessments used to identify children who may need further evaluation for developmental delays.
- Screenings are recommended at 9, 18, and 30 months (or 24 and 36 months) during well-child visits.
- Early intervention services (Part C of IDEA) are available in every state for children birth to age 3 with developmental delays.
- You do not need a doctor's referral to request an early intervention evaluation — parents can refer their own child.
- Early intervention is most effective when started early, during the period of greatest brain plasticity.
Understanding Developmental Screenings
Developmental screenings are standardized tools used to identify children who may have developmental delays. Unlike developmental surveillance, which is the ongoing monitoring of development during every healthcare visit, screenings are structured assessments that provide a snapshot of your child's skills compared to age-expected milestones.
The American Academy of Pediatrics recommends developmental screening at 9, 18, and 30 months, with autism-specific screening at 18 and 24 months. Many pediatricians also screen at other ages as needed. Screening tools are designed to be quick to administer, typically taking 10-20 minutes, and rely on a combination of parent report and direct observation.
Common screening tools include the Ages and Stages Questionnaires (ASQ), which covers communication, gross motor, fine motor, problem-solving, and personal-social skills; the Modified Checklist for Autism in Toddlers (M-CHAT), which screens specifically for autism spectrum disorder; and the Parents' Evaluation of Developmental Status (PEDS), which focuses on parent concerns.
A screening result that indicates potential concern is not a diagnosis. It means your child's development in one or more areas looks different from most children their age and warrants a comprehensive evaluation. Many children who screen positive ultimately do not have a developmental disorder after full evaluation. The screening is simply a flag to look more closely.
If your pediatrician does not offer regular developmental screenings, or if you are concerned about a specific area your pediatrician has not addressed, you can request a screening. You can also complete screening tools independently through your state's early intervention program or online through reputable sources. Trust your instincts — if you are worried, ask for screening.
Every child develops differently, and these general parenting guidelines should be discussed with your healthcare provider for personalized advice.
Early Intervention: What It Is and How It Works
Early intervention is a system of services for infants and toddlers (birth to age 3) who have developmental delays or disabilities. Established under Part C of the Individuals with Disabilities Education Act, early intervention is designed to support children during the critical early years when brain development is most rapid and intervention is most effective.
Accessing early intervention starts with a referral. You can refer your own child by contacting your state's early intervention program. Some states call it Early Steps, Early On, or another name, but every state has one. You do not need a doctor's referral, though pediatricians are a common referral source. The referral triggers a timeline: the program must evaluate your child within 45 days of referral.
The evaluation is conducted by a team of professionals who assess your child across developmental domains: cognitive, physical (including vision and hearing), communication, social-emotional, and adaptive (self-help skills). The evaluation includes parent interview, direct observation, and standardized assessment tools. You are an essential part of this process.
If your child qualifies for services, the team develops an Individualized Family Service Plan (IFSP). This document outlines your child's current developmental levels, goals for the next 6-12 months, and the specific services that will be provided to help meet those goals. Services are provided in your child's natural environment — typically your home or daycare — and are integrated into daily routines.
Early intervention services are typically free or provided on a sliding fee scale. Services may include speech therapy, occupational therapy, physical therapy, developmental therapy, and family training and support. The frequency of services depends on your child's needs, ranging from weekly to monthly sessions. The goal is to support your family in helping your child develop effectively.
Transitioning from Early Intervention to Preschool Services
At age 3, children transition from the early intervention system (Part C) to the preschool special education system (Part B, Section 619). This transition is a significant change in how services are delivered and funded. The early intervention team must begin transition planning at least 90 days before your child's third birthday.
The transition involves a new evaluation to determine eligibility for preschool services under the school-based special education framework. Eligibility criteria are different from early intervention — your child must meet specific criteria for a disability category to qualify. Some children who qualified for early intervention do not qualify for preschool services, while others do.
If your child qualifies for preschool special education, an Individualized Education Program (IEP) is developed. Unlike the IFSP, which focuses on family goals, the IEP focuses on educational goals and is implemented in a school setting. Services may be provided in a specialized preschool classroom, an inclusive classroom with typically developing peers, or through therapy sessions.
If your child does not qualify for preschool special education but still needs support, other options exist. Private therapy through insurance, community programs, and continued support from early intervention through a transition plan can bridge the gap. Your early intervention coordinator and pediatrician can help you explore options specific to your child's needs and your location.
Advocating for your child through this transition is important. You know your child best and are their most important advocate. Keep records of all evaluations, services, and communications. If you disagree with eligibility decisions, you have procedural safeguards including mediation and due process hearings. Many parents find support through local parent training and information centers.
Trust your instincts as a parent. You know your child better than anyone else. When something does not feel right, speak up and ask questions.
Frequently Asked Questions
What if my pediatrician says wait and see but I am still worried?
You always have the right to seek a second opinion or refer your child for early intervention evaluation independently. Wait and see is appropriate for some mild variations in development, but if your parent gut is telling you something is wrong, trust it. Early intervention never hurts — services support development even for children who are not significantly delayed.
Will early intervention services label my child?
Early intervention focuses on supporting development, not labeling children. The diagnosis or delay category used to qualify for services is an administrative requirement, not an identity. Many families find that the support their child receives far outweighs any concern about labels. The goal is to give your child the best possible start.
How much does early intervention cost?
Early intervention services are typically free or provided on a sliding scale based on family income. Under Part C of IDEA, services cannot be denied due to inability to pay. Some states charge fees for certain services, but evaluation and case management are always free. Your early intervention coordinator will explain any costs before services begin.
What if my child is over 3 and has never had early intervention?
If your child is 3 or older and you have concerns, contact your local public school district and request a special education evaluation. School districts are responsible for identifying and evaluating children with disabilities from age 3 through 21. You do not need a doctor's referral. Put your request in writing to start the evaluation timeline.
Conclusion
Developmental screenings and early intervention are powerful tools for supporting children's development. They exist because we know that early support makes a meaningful difference in outcomes. If you have concerns about your child's development, do not wait. Trust your instincts, seek screening, and access the services available. Early action is an act of love and advocacy for your child.
