Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Reference typical developmental milestone acquisition age ranges across gross motor, fine motor, language, social-emotional, and cognitive domains for children 0–5 years per CDC 2022 milestones

Each component has a specific meaning:

  • Gross motor — The gross motor recorded for the scenario being assessed.
  • Fine motor — The fine motor recorded for the scenario being assessed.
  • Language — The language recorded for the scenario being assessed.
  • Social-emotional — The social-emotional recorded for the scenario being assessed.
  • Cognitive domains — The cognitive domains recorded for the scenario being assessed.

Note: Interpret the developmental milestones result against the thresholds and context described above.

How to Use

Enter the gross motor, fine motor, language, social-emotional, cognitive domains for the scenario you are assessing. Reference typical developmental milestone acquisition age ranges across gross motor, fine motor, language, social-emotional, and cognitive domains for children 0–5 years per CDC 2022 milestones. Use the developmental milestones result to inform your calculation.
