The Questions I Ask in an ADHD Evaluation
When someone comes to me wondering whether they have ADHD, the evaluation is rarely about whether they can concentrate today. Almost no one can, all the time. What I am actually trying to answer is a more layered set of questions: did this begin in childhood, is it genuinely impairing your life now, and is there something else that explains it better? The rating scales help, but they are the floor, not the ceiling. The questions that do the real work are the ones that sit around the scales — and those are the ones I want to walk through here.
I share this not as a script to self-diagnose from, but because I think people deserve to understand what a careful evaluation looks like, and why being asked about your fourth-grade report card or your relationship with your manager is not a detour. It is the evaluation.
Did it start before age 12?
ADHD is a neurodevelopmental condition, which means it doesn't arrive in adulthood out of nowhere — several symptoms are present before age 12, even when no one named them at the time. So the first thing I work to establish is the childhood footprint. The trouble is that most adults can't hand me a report card or put a parent on the phone, so I reconstruct it through proxies that are concrete enough to actually remember.
I ask whether they ever failed a subject or were held back a grade level before age 12. I ask whether they met their developmental milestones on time. I ask whether they carried any psychiatric diagnosis as a child. And I ask about the patterns underneath the grades — were they the child who couldn't sit still, who lost things constantly, who was bright but never finished anything, who heard "not living up to potential" year after year?
To structure that retrospective look, I use the Wender Utah Rating Scale (WURS), a validated instrument designed specifically to capture childhood ADHD symptoms as an adult recalls them. It doesn't replace the conversation, but it gives the childhood history a measurable spine when the usual collateral simply isn't available.
What has the pattern of your adult life actually looked like?
A single hard season doesn't make a diagnosis. ADHD leaves a trail, so I look at the shape of the adult history rather than the snapshot in front of me.
I ask whether they hold a degree — not because a degree rules ADHD in or out, but because the story of how they got it, or didn't, is informative. Did they finish, and at what cost? I ask whether they've moved through multiple jobs in a short span, which is one of the more revealing real-world signals — a churn of starts and exits often says more about sustained functioning than any self-report item. The point isn't any single answer; it's whether a longstanding, repeating pattern emerges or whether the difficulty is new and circumstantial.
How much is this actually costing you?
Impairment is the word that separates a personality trait from a disorder. Plenty of people are distractible and perfectly fine. The diagnostic question is whether the inattention is genuinely degrading your work, your relationships, your finances, your driving, your sense of yourself. To measure that with some rigor rather than relying on impression, I use the Weiss Functional Impairment Rating Scale (WFIRS), which maps impairment across the domains of daily life rather than just counting symptoms.
What I'm listening for is the difference between ordinary modern busyness and real functional cost — the unpaid bills not from lack of money but from never opening the envelope, the projects abandoned at ninety percent, the relationships strained by forgotten commitments, the long-running private belief that one is simply lazy or broken. When impairment shows up consistently across several domains and across time, that carries real diagnostic weight.
What else could this be?
This is the part of the evaluation I consider non-negotiable, and it's the bridge to a piece I've written separately on the times the ADHD label didn't fit. Before I would ever commit to a diagnosis or a stimulant, I screen for what else could be producing the very same inattention.
So I ask about what's going on in the wider life — a recent loss of a job or a family member, work stress, relationship or personal upheaval — and I screen deliberately for depression, anxiety, and mood elevation or mania, because each of those can imitate ADHD convincingly. Untreated depression fragments concentration. Anxiety pulls attention toward what it's bracing against. A bipolar pattern can look like distractibility and impulsivity if you only catch it on a single day.
How I ask these matters as much as what I ask. I word them to be non-judgmental, never doubting the person's account, and never leading. Someone who already feels they've had to fight to be taken seriously will close down the moment an evaluation feels like cross-examination — and a leading question contaminates the very history I'm trying to read cleanly. The goal is to make it safe to tell me the real story, because the real story is the diagnostic information.
The questions people don't expect
Some of the most useful questions I ask have nothing to do with attention on their face. I ask where someone lives, who they live with, and what their role is in the family. I ask about their relationship with their manager or supervisor. I ask what kind of work they do and whether they're actually happy in it.
I ask these because what arrives labeled as a focus problem is, often enough, a mismatch between a person and their environment rather than a deficit inside them. A capable person in the wrong role, under a manager who undermines them, in a home situation that drains every reserve, will struggle to concentrate — and that struggle is real, but it isn't ADHD, and a stimulant won't fix a job that's the wrong fit. Asking about the context is how I tell a disorder apart from a life that has become unworkable. Sometimes the most helpful thing I can offer isn't a prescription; it's the recognition that the problem is situational and solvable.
Why the whole picture matters
Each of these questions exists to answer one of the three that frame the entire evaluation: did it start in childhood, is it truly impairing, and is it better explained by something else. A rating scale can suggest ADHD. Only the full picture — the childhood footprint, the lifelong pattern, the functional cost, the ruled-out look-alikes, and the honest look at someone's circumstances — can responsibly confirm it. That thoroughness isn't bureaucracy. It's the difference between a label that fits and one that simply got applied.
Quick answer: how an adult ADHD evaluation works
A careful adult ADHD evaluation answers three questions: did the symptoms start in childhood (established through proxies like failing a subject or being held back before age 12, developmental milestones, and the Wender Utah Rating Scale when records aren't available), are they truly impairing daily life now (measured across domains with the Weiss Functional Impairment Rating Scale, not just a symptom count), and is something else a better explanation (screening for recent loss, work and relationship stress, depression, anxiety, and mania, asked in a non-judgmental, non-leading way). Context questions — living situation, family role, relationship with a manager, job fit — help separate a true disorder from a person-environment mismatch that imitates it.

Frequently asked questions
What happens in an adult ADHD evaluation?
A thorough evaluation looks at three things: whether the symptoms began in childhood, how much they impair daily functioning now, and whether another condition better explains them. It combines a careful history with validated tools — a retrospective childhood-symptom scale such as the Wender Utah Rating Scale and a functional-impairment measure such as the Weiss Functional Impairment Rating Scale — rather than relying on a single questionnaire or a current-symptom checklist alone.
How do you prove ADHD started in childhood if there are no records?
Most adults can't produce report cards or a parent to interview, so childhood onset is reconstructed through concrete proxies: failing subjects or being held back before age 12, whether developmental milestones were met on time, any psychiatric diagnosis in childhood, and recurring patterns the person recalls from school and home. The Wender Utah Rating Scale is a validated way to capture those retrospective childhood symptoms when collateral isn't available.
Why does childhood history matter for an adult ADHD diagnosis?
ADHD is a neurodevelopmental condition, so its symptoms are present from early life, with several appearing before age 12. An attention problem that genuinely begins for the first time in adulthood, with no childhood footprint at all, usually points to something else — mood, sleep, a medical change, or stress. That's why the childhood history isn't a formality; it's central to the diagnosis.
How do you rule out anxiety, depression, or bipolar disorder before diagnosing ADHD?
Before committing to a diagnosis or a stimulant, the evaluation screens for what else could produce the same inattention — recent loss, work or relationship stress, depression, anxiety, and mood elevation or mania. These questions are asked in a non-judgmental, non-leading way so the person's own history comes through clearly. If a mood, anxiety, sleep, or substance issue is actually driving the focus problem, naming and treating that first is what helps.
If you've wondered about ADHD and want an evaluation that looks at the whole picture — not just a checklist — that's exactly the kind of careful look we offer.
