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.
We also have information on the following:
- About BMI for Adults: Information about BMI and interpreting this number for adults
- About BMI for Children and Teens: Information about BMI and interpreting the BMI percentile for children and teens
Note that the information about children and teens is written primarily for parents, but it may also be of interest to others, such as healthcare providers and the general public.
