Understanding the ASQ Questionnaire Versions
The Ages and Stages Questionnaire (ASQ) is a family of developmental screening tools designed to identify children who may need further evaluation. Different versions are used for different age groups to ensure accurate assessment of developmental milestones.
ASQ-3™ Questionnaires
The ASQ-3 is the third edition of the original ASQ and includes 19 different questionnaires for ages 1 month to 66 months (5.5 years). Each questionnaire targets a specific age range:
| ASQ-3 Version | Age Range | Key Features |
|---|---|---|
| 2 Month | 1-4 months | Focus on early reflexes, vision, and social engagement |
| 4 Month | 3-6 months | Motor control, eye tracking, communication beginning |
| 6 Month | 5-8 months | Sitting balance, reaching, babbling |
| 9 Month | 8-11 months | Crawling preparation, pincer grasp, understanding words |
| 12 Month | 11-15 months | Walking, first words, object exploration |
| 18 Month | 16-21 months | Running, pointing, vocabulary growth |
| 24 Month | 22-30 months | Sentence formation, play skills, independence |
| 30 Month | 28-36 months | Complex sentences, social play, problem-solving |
| 36 Month | 34-42 months | Following directions, peer interaction, literacy skills |
| 42 Month | 40-48 months | Complex play, cooperation, fine motor control |
| 48 Month | 46-54 months | Advanced social skills, academic readiness |
| 54 Month | 52-66 months | School readiness, complex communication, independence |
ASQ:SE-2™ (Social-Emotional)
The ASQ:SE-2 is a companion tool that screens for social-emotional and behavioral concerns. It's available for:
- 3 Month version: Ages 2-21 months
- 6 Month version: Ages 3-36 months
- 12 Month version: Ages 3-36 months
- 24 Month version: Ages 24-60 months
- 36 Month version: Ages 24-60 months
Why Age-Specific Questionnaires Matter
Using the correct ASQ version is crucial because:
- Developmental Appropriateness: Each version asks about skills typical for that age.
- Accuracy: Age-specific questions increase the reliability of screening results.
- Early Detection: Identifying delays early allows for timely intervention.
- Reduced False Positives: Using the wrong version can lead to unnecessary referrals.
- Normative Comparison: Results are compared to children in the same age range.
How to Use This Calculator

Step 3: If using a specific date, enter that date in the second field.
Step 4: Click "Find ASQ Version" to see the recommended questionnaire.
Step 5: Review the age range and key developmental areas for that version.
When to Screen Using ASQ
- Routine Well-Child Visits: Pediatricians often use ASQ at regular check-ups.
- Parental Concerns: When parents notice developmental delays.
- Risk Factors: For children with prematurity, low birth weight, or family history of delays.
- Early Intervention Programs: To identify children who need services.
- School Readiness: Before kindergarten entry for children ages 3+.
- Follow-up Screening: To monitor progress over time.
Important Limitations
The ASQ is a screening tool, not a diagnostic test. It helps identify children who may benefit from a full developmental evaluation. If the ASQ suggests concerns:
- Schedule a comprehensive developmental evaluation with a specialist.
- Consider factors like prematurity, bilingual exposure, and environmental influences.
- Always consult with your child's pediatrician or early intervention program.
- Remember that many children catch up with support and intervention.

Frequently Asked Questions
1. What if my child's age falls between two ASQ versions?
ASQ versions overlap by about 2 months. For example, both the 18-month and 24-month versions can be used for a 20-month-old. Consult with your pediatrician to determine which version is most appropriate, or you can administer both if needed.
2. Can I use an ASQ version for a child outside the recommended age range?
It's not recommended. Using a version outside the recommended age range may result in inaccurate screening. Always use the version designed for the child's age.
3. What if the ASQ screening suggests a delay?
An ASQ screening is just the first step. If concerns are raised, the next step is a comprehensive developmental evaluation by a specialist. Many children with initial concerns go on to develop typically with appropriate support.
4. Should I adjust the age for premature babies?
Yes! Premature babies should have their age adjusted until about age 2 years. For example, a baby born 3 months early at 12 months chronologically has an adjusted age of 9 months. Use the adjusted age to select the appropriate ASQ version.
5. How often should a child be screened with ASQ?
The American Academy of Pediatrics recommends developmental screening at well-child visits, typically at ages 9, 18, 24, 30, and 48 months. More frequent screening may be recommended for at-risk children.
6. Can parents administer the ASQ at home?
Yes! The ASQ is designed for parent/caregiver completion. Parents answer questions about their child's behavior and abilities in familiar, everyday situations. However, professional interpretation is recommended for accurate results.
7. Is the ASQ available in multiple languages?
Yes, the ASQ has been translated into many languages. Check with your healthcare provider or early intervention program for language availability in your area.
8. What are the 5 developmental domains assessed by ASQ?
The ASQ assesses: (1) Communication, (2) Gross Motor, (3) Fine Motor, (4) Problem-Solving, and (5) Personal-Social skills.
9. Is this calculator accurate for all children?
This calculator provides a general guideline based on chronological age. For premature babies, adjusted age should be used. Always consult with a pediatrician or early intervention specialist for individualized recommendations.
10. Where can I get the actual ASQ questionnaires?
ASQ questionnaires are available through the publisher, Paul H. Brookes Publishing Co. They can be obtained through pediatric offices, early intervention programs, schools, and online retailers. Your healthcare provider can provide guidance on obtaining the appropriate version.
