The ASQ — the Ages and Stages Questionnaire — is a screening tool, not a test.
A parent fills in a short questionnaire about how their child communicates, moves, solves problems and gets along with others, and a professional scores it and flags what may need a closer look.
The tool's developmental screener, the ASQ-3, covers ages 1 through 66 months.
Here is how the tool works and where you fit in as the teacher.
What is the ASQ-3?
The ASQ-3 is the Ages and Stages Questionnaire's developmental screener, a screening tool the publisher describes as parent-completed: a parent answers questions about what their child does, and a professional scores the answers.
It covers ages 1 through 66 months across five areas — communication, gross motor, fine motor, problem solving and personal-social.
Those five areas map onto what you already watch for in a classroom.
They run from how a child speaks and understands, to how they climb, hold a crayon, work out a puzzle and get along with the child next to them.
A screener is not the same instrument as the observational assessment a program can run alongside it.
Teaching Strategies describes GOLD, for example, as an online observational assessment for children from birth through third grade, rated against research-based objectives — in practice, the teacher scores from what they have observed and documented, not from a family's form.
The ASQ-3 works the other way around: the questionnaire travels home with a family, and you score what comes back.
Where does a teacher come across it?
In a program's screening policy, in job postings that name it, and in the day a director hands you a stack of forms to get back from families.
Screening sits on the assessment side of the classroom job — the daycare teacher career guide covers where it fits in the role overall.
Who completes the ASQ?
The design splits the work in two.
The parent completes the questionnaire — the publisher pegs it at 10 to 15 minutes — answering questions about what their child does.
A professional then scores it, which takes 2 to 3 minutes.
In a childcare program that professional may be a teacher, and the rest of the job is logistics: getting the right questionnaire to the right family, encouraging them to complete it, scoring what comes back, and passing the result through the program's screening process.
That logistics list is the real work.
The questionnaire only produces a score if a family fills it in, so the teacher-side skills are chasing the right form, making the questions feel answerable rather than like a test, and turning scores around while the result is still useful.
Head Start puts a clock on all of it.
Under the current Head Start Program Performance Standards, a program must complete or obtain a developmental screening within 45 calendar days of when a child first attends — 30 days for programs operating 90 days or less — using research-based standardized tools (45 CFR 1302.33, administered by the Office of Head Start).
That rule belongs to Head Start programs; it does not transfer to private centers, where state licensing rules are the ones to check.

ASQ-3 age intervals
The questionnaire comes in age intervals: the span from 1 to 66 months is divided into separate questionnaires, and the publisher's kit listing includes 21 of them.
Which one applies follows the child's age in months — the same age you already track on your roster and in enrollment paperwork.
For a teacher, the practical consequence is that screening is age-driven: a child's date of birth decides which questionnaire the family gets, and a room with a wide age spread means several intervals in circulation at once.
It also means the structure is one you learn once.
The questions change with each interval, but the parent-completes, professional-scores design holds across the whole 1-to-66-month range.
One detail our research notes do not pin down is the exact month each interval starts and stops.
If your program uses ASQ-3, ask your director how the program decides which interval applies to each child.
Scoring the ASQ-3 and what happens next
Scoring is quick — the publisher gives professionals 2 to 3 minutes — and the output is a result read against cutoffs.
The result the publisher highlights is the monitoring zone: results that fall near the cutoff land there, which the publisher describes as a way to make it easier to keep track of children at risk.
On the classroom floor, that band reads as a list of children to keep observing — not a decision to make on the spot.
What happens after a score is your program's call, not the form's.
A screening result is a flag for a closer look — it starts a process, it does not end one.
The product page we read describes the monitoring zone, but our research did not capture — and did not verify — the cutoff scores behind it.
The questions worth asking your director early:
- Which developmental screener the program uses, and whether it pairs a social-emotional screener with it.
- What happens after a result lands near or below the cutoff, and who owns the next step.
- Who talks with the family, and when.
- How the program decides which interval each child gets, and where it keeps its scoring materials, so you are not guessing at score bands.
None of those answers change what the ASQ-3 is — they decide what you do the day a questionnaire comes back scored.
Getting them in your first week is the difference between screening as a task you own and a task that owns you.
ASQ:SE-2: the social-emotional companion
The ASQ family has a second screener: ASQ:SE-2 screens social-emotional skills, covering ages 1 through 72 months across 9 questionnaires, per the publisher.
It is designed to be used alongside the ASQ-3 or another general developmental screener — not instead of one.
The split is worth understanding before an interview or a screening week.
The ASQ-3 touches personal-social development among its five areas; ASQ:SE-2 focuses on that social-emotional side.
A program that runs both ends up with two results per child: the broad developmental screen and the focused social-emotional one.
If a posting or an interview names one and not the other, that is a fair question to ask: which screeners the classrooms run, and who scores them.
