Children's BMI Tool for Schools

The Children's BMI Tool for Schools is an Excel spreadsheet intended for use by school, child care, and other professionals who want to compute Body Mass Index (BMI)-for-age for a group of up to 2000 children, for example a school class room or grade.

This calculator computes BMI and BMI percentiles for individual children in a group using height and weight measurements, sex, date of birth, and date of measurement information that you enter, or import from a spreadsheet or data file. It provides a group summary of children's BMI-for-age categories and graphs for Prevalence of Overweight and Obesity, and Prevalence of Overweight and Obesity by Sex.

This calculator is an Excel spreadsheet that can be downloaded onto your computer. To allow all of the features of this calculator to work, please click "Enable Macros" if prompted when you open the application. The spreadsheet has 3 worksheets entitled "INSTRUCTIONS", "MEASUREMENTS", and "GROUP SUMMARY". You can view each of these using the tabs at the bottom of the window.

Note: The English version was updated on April 2, 2009, to fix a decimal entry problem.
