Waiting for an Autism Diagnosis: What You Can Start Now

What is already available to you before the report arrives, who to call first, and what is worth writing down in the meantime.

Key Takeaways

• You do not need an autism diagnosis, or even a doctor’s referral, to request a free developmental evaluation.
• In Georgia, a child under three can qualify for early intervention on a confirmed developmental delay alone.
• The waiting period is the cheapest time to gather information, and the information you gather shortens everything that comes after.
• What you write down now is more useful to a clinician than what you remember later.
• An autism diagnosis changes which doors open, not whether your child needs support.

The referral email came through with no date on it. Someone will be in touch, it said, and you read it twice looking for a number, a month, anything. That was in April. You have since called twice, been told the list is long, and been left holding a worry that has nowhere to go, along with a quiet suspicion that everyone else knows something you have not been told.

A diagnostic evaluation is the appointment where a qualified clinician observes your child, gathers your account of their development, and decides whether what you have both described meets the criteria for autism.

Why the Wait Is So Long

The queue is not a sign that your concern was dismissed. Diagnostic evaluations take a long appointment with a specialist, and the number of families asking has risen faster than the number of people qualified to do the assessment. Georgia is not unusual in this, and neither are you for being in the line.

About 1 in 31 children has been identified with autism, according to CDC autism data. That number is context rather than a warning: it is roughly how many families are moving through the same system you are, which is most of the reason the appointment is not next week.

It also means the thing you are waiting on is a piece of paper, not permission. If you want to check what you have been noticing against something more structured, we have written about what you may be noticing at different ages.

Who You Are Actually Calling

For a child under three, the call goes to your state’s early intervention system. For a child three or older, it goes to your local public school district, which has its own obligation to evaluate. Neither route asks you to produce an autism diagnosis at the door, and neither charges you for the evaluation itself. 

Important to note: a school district autism eligibility does not work for insurance. If you want ABA covered by insurance, it has to be an evaluation by a doctor. 

What both routes assess is function rather than label: what your child can do, what they are finding hard, and where the gap between those two things sits. That is also the ground of what ABA therapy covers, if the ABA term has been used at you without much explanation attached.

The Georgia Route If Your Child Is Under Three

Georgia’s early intervention program is called Babies Can’t Wait, and it exists because federal law requires every state to run one for children under three. It coordinates services such as speech, occupational, and developmental therapy, and it is the door most families in your position should be knocking on while the diagnostic appointment sits in the future.

The eligibility point is the one worth knowing. A child can qualify on a confirmed developmental delay without a formal autism diagnosis, which means the wait-list you are on is not blocking this. We have set out how Babies Can’t Wait works in more detail, including what the intake looks like and how it sits alongside private therapy.

If your child turns three during the wait, the handover to the school district is worth preparing for rather than discovering. The two systems have different paperwork and different timelines, and families who know that in advance lose less time in the gap.

What to Write Down While You Wait

You will be asked, at the evaluation, to describe development that happened months or years ago, under fluorescent lighting, with your child climbing on the furniture. Almost nobody performs well at that. The version of you sitting at home tonight is a far better witness than the version of you in that room.

Write down what you actually see, with dates, in whatever form you will keep up. When your child first used a word and whether it stuck. What they do when the routine changes. How they respond when you say their name from across the room. What sets off the hardest ten minutes of your day, and what reliably settles it. Specifics beat impressions, and a phone note beats a good intention.

Video helps more than parents expect, because a clinician sees in forty seconds of footage what takes you a paragraph to describe. Keep the ordinary moments rather than the worst ones. When the appointment does arrive, our note on what to bring to the evaluation covers how to organize any of this.

What ABA Can and Cannot Do Before an Autism Diagnosis

Being straight about this matters more than being useful to ourselves. Haim ABA does not diagnose autism. We are an applied behavior analysis provider, meaning we teach skills in small steps, study what is happening around a behavior in order to change it, and measure progress with data. The diagnosing is done elsewhere, by a clinician qualified to do it.

What that means practically is that a formal ABA program usually needs the diagnosis, because that is what insurance authorization is built on. What does not need to wait is the conversation. An evaluation, a phone call about what you are seeing, or a parent training conversation can happen while the diagnostic appointment is still ahead of you, and any of those can tell you whether you are in the right building at all.

Haim ABA’s clinic is at 2450 Atlanta Hwy in Cumming, Georgia, and the team also works with families in their homes, in their children’s schools, and in the community across the surrounding counties.

What Changes on the Day the Autism Diagnosis Report Arrives

Less than you might think, and more than you might hope. The report does not tell you anything about your child that you did not already partly know. What it does is unlock things: insurance authorization, school eligibility categories, and access to programs that are written around a named condition rather than a described difficulty.

It is also worth deciding in advance what you want from the appointment beyond the yes or no. A useful evaluation names what your child finds hard and what would help, in language a school and a therapy team can both act on. Asking for that explicitly tends to produce a more useful document than waiting to see what arrives.

One distinction is worth carrying into that appointment, because the two words get used interchangeably and mean different things:

A screening: is a short check that flags whether a fuller look is warranted, and it can happen any time a concern comes up, from you or from a pediatrician. 

An evaluation: is the long appointment that produces the report. Being told your child was screened is not the same as being told they were evaluated, and if you are unsure which happened, that is a fair question to ask outright.

Then the practical layer starts, and it is mostly administrative. Insurance authorization, waiting periods, and what a plan actually covers are laid out in coverage in Georgia.

The sequence from a first phone call through to a first session is worth reading before you make it, so that nothing in the process arrives as a surprise. We have set out how intake actually runs, including where the waits sit.

Questions Georgia Parents Often Ask About Waiting for a Diagnosis

Will insurance pay for ABA therapy before we have an autism diagnosis?

Usually not for a full ABA program, because authorization is generally built on a diagnosis. Free developmental evaluations through early intervention or your school district are a separate route and do not depend on insurance at all. It is worth calling your plan and asking what it covers pre-diagnosis, because the answers vary more than people expect.

Does Haim ABA serve families in Alpharetta and north Fulton County?

Yes. Our clinic is in Cumming, and the team also works with children at home, at school, and in the community across the surrounding counties. Which arrangement fits is worked out with you rather than decided by distance.

My child is 18 months. Is anyone going to take me seriously yet?

Yes, and 18 months is well inside the range where early intervention takes referrals. You do not need to justify the concern or wait until it is more obvious, and the people who run the free evaluation are used to hearing from parents this early.

Can the first ABA sessions happen at home while we sort the rest out?

In-home ABA therapy is one of the settings available, and for a young child it is often where the useful teaching happens anyway. What the mix looks like depends on the child and on what the plan is trying to teach, so it is worth raising as a preference rather than assuming either way.

Should we pay for ABA therapy privately to skip the wait-list?

Some families do, and it can shorten the wait considerably. Before spending, check that the private evaluator is qualified to produce a report your insurance and your school district will both accept, because a report that one of them rejects costs you the money and the time. Ask that question in writing before you book.
