These standards have been made on 265 nursery school children from 2 to 5 years of age. Twenty-nine tables are given of the standing height, weight, weight-height index, stem length, recumbent length, stem-stature index, mental level by the Stanford Revision Test, Merrill-Palmer scale and the Goodenough drawing test, Monroe scale, activity, food intake, lunch time, sleep and cause of absence. The percentage method is used in the tables, which may not be clear at first glance. A method of consolidating these data for individual children, called a biogram, is given.
