There are multiple grading scales for rating the severity of acne vulgaris.  Three techniques include the Leeds acne grading technique, which counts and categorizes lesions into inflammatory and non-inflammatory (ranges from 0 to 10.0), Cook's acne grading scale, which uses photographs to rate severity from 0 to 8 (0 being the mildest or least severe and 8 being the most severe), and the Pillsbury scale, which classifies the severity of the acne from 1 (least severe) to 4 (most severe).
