Body Mass Index (BMI) Measurement in Schools - Safeguard 3
Safeguard 3. Ensure that the setting for data collection is private.
Height and weight measurements must not be conducted within sight or hearing distance of other students. The trained staff member conducting the measurement can be the only person to see the results and can not announce them out loud.1 To maintain anonymity when collecting data for surveillance purposes, school staff can remove identifying information, including the student’s name, from the data collection form as soon as record keeping is complete and prior to calculating BMI and aggregating and analyzing the data.2
