Students in grades K to 5 who are overweight or obese, according to their height and weight, as reported by a parent or guardian

This indicator is calculated by dividing the number of respondents who "have a BMI higher than an age/gender specific cutoff" by the number of respondents who "provided the height and weight of their child". The BMI is obtained by dividing the weight in kilograms by the height in square metres. Conversions are applied to obtain the correct unit of measure from the following questions: How much does your child weigh without their shoes on? And how tall is your child without their shoes on?

Due to the very low response rate for the 2025-2026 parent questionnaire, survey results may not be representative of the overall student and parent population. Therefore, results should not be used for planning or comparing to previous editions of the survey. Some schools will not receive their K to 5 results due to the extremely low number of parents who responded.
