You've just finished the six ASRS questions and you're looking at a number: 4 out of 6. Or 2. Or 6. And the obvious next question is — what does that actually mean?
The ASRS-v1.1 Part A is the World Health Organization's six-question adult ADHD screener, and its score is one of the most misread numbers in mental-health self-assessment. People treat it like a percentage ("4 out of 6 is 67%, so… mostly ADHD?"), or compare it to point totals from unrelated quizzes, or assume a 6 means severe and a 4 means mild. None of that is how it works. This article explains what the number is, what each score from 0 to 6 signals, and what a sensible next step looks like at every level. If you haven't taken the screener yet, take it first — it's six questions, about two minutes — and read this with your result in hand.
First: your score is a count, not a total
Most quizzes add up points. The ASRS doesn't. Each of the six questions is checked against its own threshold, and your score is simply how many questions crossed their threshold — the number of "shaded responses," from 0 to 6.
The thresholds are not the same for every question. On the version of the instrument this site implements:
- Questions 1–3 (finishing the final details of a project, getting organized for a demanding task, remembering appointments and obligations): answering Sometimes, Often, or Very Often counts as a shaded response.
- Questions 4–6 (delaying tasks that require a lot of thought, fidgeting or squirming when seated, feeling "driven by a motor"): only Often or Very Often counts. A "Sometimes" here counts for nothing.
The name comes from the original paper form, where the answer boxes that count are literally shaded gray. Why the uneven thresholds? Because the questions differ in how ordinary an occasional "yes" is — nearly every adult sometimes procrastinates on hard tasks, so that answer carries no signal, while even a "Sometimes" on chronically missed appointments turned out to predict real cases. Each threshold was set empirically, based on what actually discriminated adults with ADHD from adults without it in the validation research. (The full story of who built the instrument and how it was validated is in our ASRS-v1.1 explainer.)
Two practical consequences before we get to the score bands:
A 4 is not "worse" than a 3 by one unit of severity. The score counts how many symptom areas cleared their bar, not how intense anything is. Someone with three areas rated "Very Often" scores lower than someone with four areas rated exactly at threshold.
You can't compare it to other tests' numbers. A "14 out of 24" on some other ADHD quiz and a "4 out of 6" on the ASRS are not on the same scale, or any shared scale at all.
The score bands, one by one
The instrument itself draws one line: four or more shaded responses is a positive screen. In the published research, adults at 4+ had symptom patterns highly consistent with adult ADHD and were flagged for full evaluation. Our screener additionally breaks the below-threshold range into graded bands — 0–1, 2, and 3 — because "negative" covers a lot of ground and a single label wouldn't help you decide what to do. Here's how to read each result.
0–1 shaded responses: very few indicators
Almost nothing crossed a threshold. Everyone loses focus, fidgets, and forgets things occasionally — the screener is built to ignore that ordinary background noise, and your answers stayed within it.
What this doesn't rule out: a bad fit between your real difficulties and these particular six behaviors. If you're genuinely struggling — at work, in relationships, with daily follow-through — a low ASRS score doesn't mean nothing's wrong; it means this particular pattern isn't lighting up. Sleep problems, anxiety, depression, and chronic stress all impair attention and are worth exploring with a doctor in their own right. And if you're not sure what adult ADHD even looks like beyond stereotypes, start with what adult ADHD actually is.
2 shaded responses: some indicators
A couple of areas cleared their bar — noticeable, but well below the screening threshold. This is common territory for busy, overloaded, or under-slept adults, and by itself it isn't a signal that warrants an ADHD evaluation.
A reasonable move at this level: watch and re-check. Keep loose notes for a couple of weeks on where follow-through, organization, or restlessness actually cost you something. If your circumstances change — or the problems feel lifelong rather than situational — retake the screener; it reflects the past six months, so it can legitimately shift.
3 shaded responses: one below the line
Three is the awkward score: one shaded response short of a positive screen. Formally, it's negative. Practically, it deserves more attention than the number suggests, for one specific reason — the screener's known weakness runs in this direction.
The ASRS's accuracy profile is lopsided by design. In a large follow-up validation (Kessler et al., 2007), its specificity was extremely high — above 99% — but its sensitivity was moderate, catching roughly two-thirds of true cases at the standard threshold. Translated: the screener almost never flags people who don't have the pattern, and pays for that by missing a fraction of people who do. Adults with heavy coping systems, and many women whose symptoms skew inattentive and internal, are overrepresented among those misses — a pattern covered in more depth in ADHD in women.
So a 3 with real-life impairment — chronic job difficulties, relationship friction over reliability, a lifelong sense of running harder than everyone else to stay level — is still worth raising with a professional. The cut-point is a screening convention, not a verdict about you.
4–6 shaded responses: positive screen
Four or more shaded responses is the published threshold: your answers match the pattern that, in validation research, was highly consistent with adult ADHD.
Here's the part worth absorbing if you scored "4 out of 6" and are tempted to shrug it off: because the screener's specificity is above 99%, false alarms are rare. This isn't an online quiz being generous to keep you engaged. Very few adults without ADHD-consistent symptoms cross this threshold. A positive screen is a genuinely informative result — informative enough that the appropriate response is a professional conversation, not another dozen internet tests hoping for a different answer.
And within the band, resist over-reading the differences: a 6 is not "severe ADHD" and a 4 is not "mild ADHD." The ASRS doesn't measure severity, and it doesn't diagnose anything. All scores in this band carry the same recommendation — a full evaluation.
A positive screen is not a diagnosis
This distinction is load-bearing, so let's be concrete about it.
A screener detects a pattern. A diagnosis identifies a cause — and several conditions can produce ASRS-elevating symptoms without being ADHD: anxiety disorders, depression, sleep apnea and chronic sleep deprivation, thyroid problems, even a sufficiently chaotic season of life. A diagnostic evaluation also requires things no six-question form can see: evidence that symptoms go back to childhood, impairment across multiple settings, and a clinician's differential judgment across those look-alikes. What that evaluation involves — who can do it, what they ask, what rating scales and history-taking look like — is laid out in how ADHD is diagnosed.
The practical next step after a positive screen is simpler than people expect: bring the result to a primary-care doctor or a mental-health professional and say, "I screened positive on the ASRS-v1.1 and I'd like a proper evaluation." A specific, evidence-based opening like that gets a far better response than "I think I might have ADHD" — it tells the clinician exactly which door to open.
Things that can skew your score
Before treating any single result as fixed, remember what the instrument is: self-report, over a six-month window. A few honest caveats:
- An unusual six months moves the number. A brutal work stretch, a new baby, grief, or a major move can inflate scores; an unusually structured, low-demand period can deflate them.
- Sleep debt mimics ADHD. Chronic short sleep impairs exactly the functions the ASRS asks about. If your sleep is wrecked, that's worth fixing or evaluating in parallel.
- Self-perception varies. Some people underrate lifelong symptoms because they've never known anything else; others overrate temporary ones under stress.
None of this makes the screener unreliable — it makes it a snapshot. If your result surprised you in either direction, retaking it after a more typical stretch, and answering with a specific recent month in mind, is a fair check.
The bottom line
Your ASRS score is a count of how many of six symptom areas crossed their evidence-based thresholds. 0–1 means the pattern isn't showing; 2 means a few threads worth loosely watching; 3 means formally negative but worth a professional conversation if you're genuinely impaired; 4–6 means a positive screen that deserves a real evaluation — and, thanks to the screener's very high specificity, one you should take seriously.
What the number is not: a severity rating, a percentage, or a diagnosis. It's a well-validated answer to one narrow question — "is this pattern worth a professional's time?" — and at 4+, the answer is yes.
