Steps to plot and interpret BMI-for-age
The six steps outlined here to plot and interpret BMI-for-age are similar to those used for a general growth assessment.

An instruction sheet on the Use and Interpretation of the WHO and CDC Growth Charts For Children from Birth to 20 Years in the United States Cdc-pdf[PDF-206KB] contains detailed instructions for the above steps.
