Many factors contribute to the development of his school efficiency. Often only by considering a factor in reference to a large number of children can it be determined whether it is favorable or unfavorable to a child’s school advancement. In the report of last year we were enabled to say that the evolutionary ideal child stood somewhere above the average in each measurement, and later to demonstrate that the more advanced pupils stood higher in the physical measurements than the back- ward ones. By taking the average number of school grades made by the several percentile groups of a given age we are enabled to compare the school efficiency of these groups. In order to present this matter on a broad basis, and to reduce it to a form sufficiently condensed to show at once the relation of school standing to physical condition abstractly, and dissociated from age and sex, we have proceeded as follows:](https://iiif.wellcomecollection.org/image/b22467506_0038.jp2/full/800%2C/0/default.jpg)
