The IAP Growth Chart 2015 screen displays the Indian Academy of Pediatrics' revised growth charts for children aged 5–18 years inside an embedded interactive chart view. It is intended as the Indian-population-specific complement to the WHO standards used for children under 5, and the embedded chart itself notes that children under 5 should use the WHO standards instead. The chart is rendered from a bundled HTML asset with its own percentile plotting and citation.
5–18 years, per the app's chart subtitle and the embedded chart's own validation message.
The app's embedded chart explicitly states to use WHO standards for children under 5 years.
