How to Measure a Child’s IQ

The following are commonly used methods for assessing children’s intelligence: 1. **Screening tests**: - The Bayley Infant Neurodevelopmental Screener is suitable for infants aged 3–24 months. - The Preschool Children’s Ability Screening Test (50-item version) is appropriate for children aged 4–7 years and primarily evaluates intellectual level, serving as a reference for school enrollment. 2. **Diagnostic assessments**: - The Bayley Scales of Infant Development are applicable to infants and toddlers aged 2–30 months. - The Gesell Developmental Schedules are suitable for infants and toddlers aged 1–36 months. - The Wechsler Intelligence Scale for Children is divided into two age-based versions: one for preschoolers and another for children aged 6–16 years. 3. **Home-based self-assessment tools**: - The Neurobehavioral Developmental Assessment Checklist for Children Aged 0–6 Years evaluates five domains: gross motor skills, fine motor skills, adaptive behavior, language, and social-emotional behavior. Intelligence assessment using this tool should be conducted under the guidance of a healthcare professional.
