Meeting-report account of Woolley and Fischer's comparative study using percentile standing of working versus school children aged 14 and 15. The report notes "the school group stood above the working group in all tests, physical as well as intellectual."

"The percentile method of locating the standing of children was used to very excellent advantage by Helen Thompson Woolley and Charlotte Rust Fischer in their study of the "Comparative Rank in Mental and Physical Tests of 14 and 15 year-old Working Children with 14 and 15 year-old School Children." The most striking of the results shown was that the school group stood above the working group in all tests, physical as well as intellectual."
